[mighty frigate]

I'm not an expert at bundling python app, so maybe I'm missing something here. Maybe I got something really wrong when doing my tests

[light vault]

Yikes @mighty frigate

[mighty frigate]

what's your point ?

[swift storm]

wtf, ultimaker cura is completely written in python (with PyQt), thats very cool

3d printing software

even the 3d render is done in python, didnt know it was capable of that

[sleek hollow]

No, it has to occur during a callback of some sort. All GUI functionality will occur in function calls once the window is shown

[swift storm]

^ either delay your .get() in a thread or do it on a callback

[sleek hollow]

Thread would really be overkill. It just needs to be tied to some sort of gui event like a button click

[swift storm]

i agree

its an option tho :d

[languid cipher]

oh okay. I have one more question

nevermind, sorry I fixed it

[inland wedge]

they are probably calling opengl functions from python

[hot solstice]

someone here uses python Flet or Flutter?

[swift storm]

Is QtQuick available for PyQt? Or do I have to stay at QtDesigner

Yes, ultimaker Cura is a good example of this

[swift storm]

Also this is bullshit

I have a 'compiled' (pyinstaller) customtkinter interface for controlling a robot. I can tell you that it does not get cached

He's also non-specific about what is being cached but whaterver

Also, if you really were to distribute your python application commercially/prevent people stealing your code (which is easy with PyInstaller). I recommend Nuitka. Nuitka compiles python code to C and applies compile-time optimizations (its great). Because it compiles to C first and then produces a binary executable from this C code, its basically irreversible to your Python code

only works with CPython interpreter though, not PyPy etc

[light vault]

I've not used Cura. Will like to try

[light vault]

Not sure why the interpreter is needed for this considering you're not running python code

Except it's converting to bytecode and interpreting first before converting the bytecode to C, but that seems weird

[swift storm]

it needs the cpython internals

the specifics i dont know

its just made for cpython's C API is my guess, though dont quote me on that

[swift storm]

download any 3d printable .stl file online and download ultimaker cura

it performs well once the app actually runs, but the loading indeed takes quite long

[light vault]

This assumes usage of compiled langs prevents reverse engineering

If it's about compilation to native machine code, there's Cython for that

That just adds an extra layer of abstraction

• if you don't want a potential reverse engineering, just give your users web apps

Currently, I'm only concerned about the perf for Python-based gui apps

I'm still building with PyGObject so I'm yet to have a solid verdict

[light vault]

I was trying to install it on my windows 8 vm

Will see how that goes

[light vault]

• I'd prefer the Cython project to the Nuitka (still don't know what this is) project really

Nuitka seems to be transpiling before compiling.

[swift storm]

why'd u use win 8 as a vm

[swift storm]

? Cython and Nuitka are unrelated lol

[light vault]

I know they are

[swift storm]

well yes they are to some extend

does cython also allow python to be a binary executable

[light vault]

It's just a vm I use for random stuff

[swift storm]

without actually shipping the interpreter along with it

[light vault]

It compiles Python

basically

[light vault]

There's no interpreter

It doesn't use CPython

[swift storm]

?

pyinstaller ships the interpreter with it

thats what pyinstaller does

[light vault]

Yep. But that's not generating a binary though

[swift storm]

and wraps this in a standalone executable

[light vault]

It's just an executable

[swift storm]

no, its a binary executable that has the interpeter inside of it

just like nuitka (idk about cython)

except nuitka compiles to C and doesnt include a interpreter

[light vault]

binary executable === executable containing machine code

[swift storm]

first

[swift storm]

you dont understand what im saying

its still the interpreter thats executing and interpreting the python code

[light vault]

Exactly. So it's not a binary executable

It didn't generate any machine code

But it's an executable

I'm just being pedantic for sure

[swift storm]

bro what

it is a binary executable?

a .exe = a binary executable

thats literally what a exe is

how they bundle the python interpreter in there along with your packages and python files, i dont know

but yes nuitka:
transpiles python into c
and then compiles this as if it was jsut a c program

[light vault]

this isn't always the case as we've seen with pyinstaller

[swift storm]

show

[light vault]

I've explained before

[swift storm]

a .exe is literally encoded binary

idk what youre saying thats literally what a .exe is

if you have any .exe ever, its a binary executable

enough 'binary executable' because this is just a pointless discussion

[light vault]

In the case of pyinstaller, it's NOT machine code

[swift storm]

if you dont want your python executable to be reverse engineered, not be large in size (due to pyinstaller shipping the interpreter) and be fast, then use Nuitka

[swift storm]

😭

[light vault]

It's just embedded CPython and byte code

[swift storm]

a .exe is fucking machine code what are you talking about LOL < im wrong here

[light vault]

Prove to me then

Not the same for pyinstaller

How is the machine code generated?

[swift storm]

how the fuck do i gotta know that

do i look like the creator of pyinstaller

[light vault]

Yet you claim I'm wrong?

It's simple. Python is an interpreted language

The Pyinstaller executable still uses the interpreter

It is NOT compiled, like Cython

So while it's an executable, it's not binary in the trad sense

[swift storm]

yes i think youre right

Cython doesnt do the C to executable for u tho

right

[light vault]

Na

It compiles python directly to machine code

So I think the compiled/interpreted dichotomy is just funny

Java is both compiled and interpreted

[swift storm]

? i think this is incorrect

is this an option

because the standard is that you can compile your .py into C code

[light vault]

Yes, I think that's what it does actually

generates C code first

[swift storm]

oh well whatever

imo, Nuitka is one of the good ways to create python exe's and actually make it ready for distribution

[light vault]

If the compilation is the problem, then Cython does same job then

[swift storm]

i mean, nuitka already does the C to exeuctable compiling

Cython doesnt, you need a seperate thing for that. Tho it doesnt really matter

[light vault]

yeah right

With nuitka, you don't use static typing?

[swift storm]

no i dont think so

i dont know cython too well but

cython does really put an emphasis on typing everything right

wouldnt be an issue for me, i type hint everything xd but still

does seem like nuitka also benefits from type hinting

[light vault]

static typing is optional in cython

The nuitka project is really different from Cython in that it creates standalone binary executables.

Cython doesn't do that. It just creates shared object files you can import

[swift storm]

can you elaborate on shared object files

[light vault]

Those are python extension modules (.so on UNIX-like systems and .pyd on Windows)

Basically, Cython "transpiles" (not sure why they say compile) Python to C

And then the C compiler is used to generate the .so file

The file can be imported in Python/CPython code like a regular python module

Still maintaining the Python API

So with Cython, you still kinda rely on CPython

Nuitka is different

Of course, Nuitka relies on CPython too but it's embedded in the executable and which is not really interpreted

[mighty frigate]

yes, and afaik QtQuick and QtDesigner aren't related in the way you imply

you can use QtQuick without QtDesigner

regardless of the stack you're using I mean

[hot solstice]

the old discussion that nuitka is better than cython, eeww

[mighty frigate]

if you have constructive criticism, it would be better than random useless edgy comment

[hot solstice]

now you're critic about being kind? man, just do whatever you want

[mighty frigate]

it's not really about being kind or not, it's about learning stuff. I think we're all here to learn and/or share. If you explain your point of view I could have learn something.

[swift storm]

They have different purposes lol

Nuitka is for the sake of a (distributable) executable, cython is for the sake of transpiling and optimizing to C code and back

The <@&831776746206265384> have been alerted for review.

[light vault]

There was never a conflation on my part though

I also think comparing them is a category error

Cython doesn't completely replace CPython.

For a full app, you still need CPython, even with optimised Cython code

[swift storm]

Doesnt cpython support cython in their own to byte code compiler

Or that done after?

I dont know cython’s role in cpython

[light vault]

Cython's role ends at transpiling to C IMO

[swift storm]

👍

[light vault]

The C compiler is responsible for generating the shared object or dynamically linked library which the CPython code calls

To use the .so or .pyd file, you use the ctypes module I guess

For those who already know C/C++, I don't think you need Cython

[somber hemlock]

You do not need ctypes for pyd

The import machinery supports it

[light vault]

You're right

I forgot

I don't use Windows :)

[somber hemlock]

Combined with a .pyi alongside it is how most libs are working

[grand sequoia]

nuitka can be used to make code more efficient, just like mypyc or cython

[swift storm]

id prefer cython for that tho

cython seems to do a better job at that

than nuitka

[grand sequoia]

in my experience, nuitka produces faster code than mypyc and cython (if you give cython pure python code)
of course, if you write in cython lang, it will produce faster code

[light vault]

How is nuitka able to produce fast code w/out static typing?

[grand sequoia]

magic of nuitka

they can do a lot of cool tricks, check out their docs

[teal drum]

how do you download a specific package to a different version of python

[light vault]

You can use virtual environments?

I have this code to open up a popup dialog when the button is pressed. It does that, but when I close the dialog, the program freezes for several seconds, and then the main widget closes. There is no error message. What is causing this and how do I fix it?

from PyQt6 import QtCore, QtWidgets, QtGui
from PyQt6.QtWidgets import QDialog, QMessageBox
import sys

class MyWidget(QtWidgets.QWidget):
    
    def __init__(self):
        super().__init__()

        self.setWindowTitle("window")
        self.Button = QtWidgets.QPushButton("button")
        self.layout = QtWidgets.QVBoxLayout(self)
        self.layout.addWidget(self.Button)
        self.Button.clicked.connect(self.ButtonClicked)

    def ButtonClicked(self):
        dlg = QMessageBox.critical(self,'Error','message')
        dlg.exec()
            
if __name__ == "__main__":
    app = QtWidgets.QApplication([])
    widget = MyWidget()
    widget.show()
    sys.exit(app.exec())

[swift storm]

is it not good practice to subclass QApplication btw? just asking

recently transitioned from tkinter to pyside/qt

[azure talon]

Anyone good at tkinter? TL:DR I have the screen update when an event happens and doesn't really need to any other time. But sometimes a label or frame will just disappear and not come back for sever updates or if i resize the screen. Any idea how to fix this? doing a self.root.update() with or without an after only causes flickering.

[sleek hollow]

QMessageBox.critical handles the exec. It returns the button that was clicked, which means you don't need dlg.exec() on the next one

[celest osprey]

That fixed it, thank you!

[wary birch]

Does anyone know how i can rebind a scrollbar in tkinter?

i followed a tutorial which shows me how to make a scrollbar using canvas so i made one but now i want to update the contents of the frame in the canvas to contain variable amount of things but the scrollbar does not update to that

#create scrollscreen
scrollScreen = Frame(homeScreen,width=420,height=360,bg="black", bd=5)
scrollScreen.pack_propagate(False)
scrollScreen.grid(row=1, column=3, sticky='news',rowspan=10,padx=20)
#create feed canvas
feedcanvas = Canvas(scrollScreen,background='black')
feedcanvas.pack_propagate(False)
feedcanvas.pack(side=LEFT,fill=BOTH,expand=1)
#create feed
feed = Frame(feedcanvas,background='black')
#add feed to feed canvas window
feedcanvas.create_window((0,0),window=feed,anchor='nw')

def updateScrollBarFeed(event):
    feedcanvas.configure(scrollregion = feedcanvas.bbox("all"))


feedscrollbar = ttk.Scrollbar(scrollScreen,orient=VERTICAL,command=feedcanvas.yview)
feedscrollbar.pack(side=RIGHT,fill=Y)
feedcanvas.configure(yscrollcommand=feedscrollbar.set)
feedcanvas.bind('<Configure>',updateScrollBarFeed)

[azure talon]

If your screen is rebuilding or auto updating regularly, you'll need to call / create an update function. You can make it specific to the scroll screen if you want. Then when adding something new, it'll show.

[terse pine]

So I'm fighting with tkinter and its docs. All I'm trying to do is grab the first display line in the box that I create, but it's not really working out. This is the section I was trying to understand in the docs about indices and such: https://tkdocs.com/tutorial/text.html#modifying
So at first I was trying to use that n.end: index, which should be the end of the nth line, but further down I saw something more interesting

Line numbers in indices are interpreted as logical lines, i.e., each line ends only at the "\n." With long lines and wrapping enabled, one logical line may represent multiple display lines. If you'd like to move up or down a single line on the display, you can specify this as, e.g., "1.0 + 2 display lines".

So then I try something like
mytextbox.get('1.0', '1.0 + 1 display lines")
and that... gets me the first character and nothing else? Any idea what I'm doing wrong here?

[royal cape]

it seems to only work correctly once the UI is actually rendering, otherwise it gives that dubious output ```py
from tkinter import Text, Tk
from tkinter.ttk import Button, Frame

app = Tk()
app.grid_rowconfigure(0, weight=1)
app.grid_columnconfigure(0, weight=1)

frame = Frame(app, padding=10)
frame.grid_rowconfigure(0, weight=1)
frame.grid_columnconfigure(0, weight=1)
frame.grid(sticky="nesw")

message = ", ".join(map(str, range(100)))
text = Text(frame, width=40, height=10)
text.insert("1.0", message)
text.grid(row=0, sticky="nesw")

def callback():
print(text.count("1.0", "end", "displaylines"))
print(text.get("1.0", "1.0 + 2 display lines"))

button = Button(frame, text="Count", command=callback)
button.grid(row=1)

app.mainloop()```

[placid nebula]

Hi, i need example of easy solution how to pass data from one tkinter window to another. Anyone is able to show some code?

[sleek hollow]

It depends what you mean? The window itself doesn't store the data. The code responsible for displaying the window is where the data is held

[placid nebula]

From entry to treeview, but the object is not important, more important is how to do it. Since i create new windows with variable which i declare function in another file. I need to pass data from one opened window to another.

[sleek hollow]

What widget are you using for your extra windows?

[placid nebula]

Tk

[sleek hollow]

Then you won't be able to. You shouldn't/can't have more than one Tk at a time

Tk is your event process and main window

if you want additional windows in a single UI program, you should be using tk.Toplevel

are you using classes in your UI?

[placid nebula]

No, just functions.

Each window is in function, which are imported

[sleek hollow]

That's going to be an issue then

Use tk.Toplevel

[placid nebula]

Ill try it later at home, ill come back if there's still issue. Thanks for now

[sleek hollow]

I'll share a basic toplevel example, 1 sec

import tkinter as tk

class MainWindow(tk.Tk):

    def __init__(self):
        super().__init__()
        self.entry = tk.Entry(self)
        self.entry.pack()

        tk.Button(self, text='Press Me', command=self.update_popup).pack()

        self.popup = tk.Toplevel(self)
        self.popup_text = tk.Label(self.popup)
        self.popup_text.pack()

    def update_popup(self):
        self.popup_text['text'] = self.entry.get()


root = MainWindow()
root.mainloop()

this creates two windows. If you type something into the main window and press the button, it updates a label in the other window

[azure talon]

My tkinter window has an issue with displaying everything.
every time I run the window update not all frames are visable anymore. If i resize the window in any way, it all gets fixed till the next update.
Anyone know how to fix this? I'm sure it's cause I have too many frames.. not sure how to reduce that and still work the same way.

Or if anyone can look at what I'm working on and suggest a better option for the ui

[clever palm]

is class-based tkinter the only way to go? im not used to OOP and much prefer manipulating functions and such,

is there a genuine major advantage to using class-based tkinter?

[sleek hollow]

class based GUI in general is very nice. I also think GUI is a nice approachable way to actually understanding OOP and becoming more comfortable with it. Subclassing widgets to create new widgets with custom functionality is very powerful

for example I created a custom class that creates this widget. Now I can reuse this in any project going forward. Useful for image or text offsetting

[clever palm]

what about for entire pages though

i understand subclassing to make individual widgets but

[sleek hollow]

it's still very handy to be able to use attributes to manage the state of your UI more easily

but also, if you're at the point where you want to use classes for GUI, I think you're ready to move on from tkinter to something better

[sleek hollow]

Feel free to paste the code here to share. You're much more likely to get help if you share your code upfront

[azure talon]

thank you, i'll do that.

[terse pine]

that is so weird, I thought it might've been some race condition or something? But even after using sleep(5) before calling print(text.get("1.0", "1.0 + 2 display lines")) it still only prints a single character, but I made a button like you did, and it seems to work fine. Dunno why it messes up if I just call it directly

I'm not going to want to tie it to a button... so I wonder if I can figure out what's going on. I'm basically making a very basic typing test, and one text box will be just to show the text the user needs to type. Playing with functions to see how I'll match everything in the first line, so I can delete it and add new words to the bottom as they finish the words in the first line.

[azure talon]

I think it's too long, comes up as message text when I try to paste it. Is that acceptible?

[sleek hollow]

You can use our pasting service here

!paste

TL:DR I'm creating an outdoor bowling scoring system.
Can't get the screen to show everything all the time, some frames go missing at full screen after and update.
Code here:
https://paste.pythondiscord.com/GIWA

[azure talon]

Thank you very much.

[sleek hollow]

hmmm yeah I see it happening on my end too, but I'm really not sure

I've never built a tkinter gui with this many widgets on screen at once

I use pyqt for larger UI

[azure talon]

I'm bad at qt, I am trying pyside 6, but haven't used it before. I know it's using the QT, just haven't done QT in a long time.

[sleek hollow]

Either way, I would really recommend separating the bowling logic from the UI logic

and I would also recommend creating subclasses for reusable UI elements like your frames

[azure talon]

Other then better code writing, i'm still amature writer, but do you think that might or could help as well. separate the script action into small processing chunks?
And do you mean something like a main window class, game window class, action class type deal?

[sleek hollow]

every frame behaves the same way, yes? It's a box that can display 3 bowl values, and a total?

or 2 values?

I don't know lawn bowling at all

[azure talon]

with symbols and F foul.
It's 5-pin bowling but outside so the frame rules stay the same

[sleek hollow]

but either way, every frame is identical information (maybe with an exception of final frame?). You can create a separate class (inherit from tk.Frame) that displays this information. Then you can create instances of this custom frame class and update the values as required

you can have another subclass for BowlersFrames or something like that

that's a bowler, and all the frames that this bowler will bowl

then another class called BowlingMain or something that holds all of the bowlers, and can contain the additional information you have at the bottom

then you can have a separate class responsible for the actual gameplay. It keeps track of who's turn it is, what they bowled, etc. Ideally it would work just the same if it was a text based CLI game

and then you can connect all the outputs of the gameplay into the GUI

it's definitely not an easy task though, at least not for something this large

[azure talon]

My first goal in writing this was to create as few break points or points of failure as possible. My first attempt was 3 times as large. 😄
after this i need it to send the info back and forth between two lanes as player swap lanes based on the number of frames bowled. but will have to grab the score from the other lane and send it here.
So it's going to get bigger.

[sleek hollow]

that's a big reason why subclassing will help. You can simply write methods for these subclasses that make it easy to get/set their values

[azure talon]

like the scoring stuff will be on a "server" deal and the lane sends over the pin information then send back the results to update the display with.

I hear you and love the feed back. I appreciate it.

[sleek hollow]

Is this for mock data or this going to be really used for bowling?

[azure talon]

going to be used. My friend owns an alley and wants to promote bowling more by doing events during teh down time (summer time)

[sleek hollow]

I would highly highly recommend switching to pyside then. It has way better integration with async serverside/db functions

it will also look nicer too 🙂

[azure talon]

But i hate learning! Mwahahaha. So I might be on the right track with that, good to know.

[sleek hollow]

Just need the right teacher, haha

[azure talon]

Yea not good at self learning, i'm not my best teacher

😄

[terse pine]

this is very strange indeed, even the count() method doesn't work right if set to automatically run. If I just put text.count('1.0', 'end','displaylines') after creation and inserting words into the the text box "text" I get (364,), even though there are only 10 display lines. If I once again put it in its own function and have a button call the function, I get 10 like I should 🤔

[sleek hollow]

is it counting the lines or the characters?

[terse pine]

now if I keep it a separate function, but have it automatically call that function without using a button, I get another number altogether, 340 lmao

it's the exact same code, just whether I'm directly calling it or putting it into a function

but it should be display lines

both get() and text() and working as I would expect when I use a button to trigger them, so I'm assuming I'm, in general, using them correctly, just something more specific to calling them maybe too soon after initializing the text box? I don't really get it.

I tried putting sleep() but a part of me wants to think that wouldn't matter, I guess the program just stops for 5 seconds, so while it seems like I gave it 5 seconds before processing the next thing, perhaps because the program is frozen for that time, it still technically is happening an instant later in terms of processing

[sleek hollow]

@terse pine Can you explain what exactly you're trying to achieve? Remove the first line from a text box and add another line to the bottom?

[terse pine]

That's the end goal, right now I'm just trying to understand how these functions work. Basically the end function is it should compare what you're typing in textbox2, with the text already in textbox1, and as you finish the first line, all the text "move up one" to reveal another line, I could also try to make it auto scroll as well, but I'm also strugglign with the see() command, and not really sure how to get it to work with "display lines"

this very second I'm trying to figure out why I can't get these functions to give me the correct values when they're not called by a button

and now weirdness I'm getting even with a button press. I decided to try and get it to print one display line at a time, it prints the correct number of total display lines (they go past the set dimensions of the box) but the for loop only returns the first display line and a bunch of blank lines 🤔

    def gettext(self):
        print(self.T2.count('1.0', 'end','displaylines')[0])
        for i in range(1,self.T2.count('1.0', 'end','displaylines')[0]):
            print(self.T2.get(f'{i}.0', f'{i}.0 + 1 display lines'))```

oh nevermind, I get what I did wrong with this latest function, '2.0' doesn't actually mean anything since that is "newline" separated lines, which I only have 1 line, I need to work out the logic some other way so it goes by display lines only

[sleek hollow]

@terse pine Here's some small sample code that cycles the lines

from string import ascii_lowercase as letters
import random
import tkinter as tk

current_spot = 5

def cycle_line():
    global current_spot
    text_box.insert(tk.END, lines[current_spot] + '\n')
    current_spot += 1
    text_box.delete('1.0', '2.0')


lines = [letters[0:i] for i in range(1, 27)]

root = tk.Tk()

text_box = tk.Text()
text_box.pack()

tk.Button(text='Test', command=cycle_line).pack()

for line in lines[:current_spot]:
    text_box.insert(tk.END, line + '\n')

root.mainloop()

it deletes line 1, and adds a new line to the end

click the Test button at the bottom to try it out

[terse pine]

where does 27 come from?

[sleek hollow]

that was just to create my example data, it's not really important for the overall logic

but 27 because range stops 1 before so I get 1-26, but I'm slicing [0:i] which also stops one before, so we're getting [0:26], which is all the letters of the alphabet

I probably could have written it nicer, but it was just to generate sample data so it wasn't important

[azure talon]

Could I do something like this:

I'm sure I'm doing something wrong but testing for now.

class Widget(QWidget):
    def __init__(self):
        super().__init__()
        
        grid_layout = QHBoxLayout()
        
        for i in range(10):
            
            frame_layout = QGridLayout()
            
            foul_frame = QPushButton("1")
            ball1 = QPushButton("X")
            ball2 = QPushButton("/")
            ball3 = QPushButton("R")

Yes, I think I got it but have to shrink it a bit.

You're still trying to cram all the functionality into a single widget

One sec

[azure talon]

This is where my amature is still showing. 😉

[sleek hollow]

Can you show me an image of a bowling frame for 5 pin?

[azure talon]

one sec

[sleek hollow]

is this correct?

[azure talon]

There's a 4th space at the top left for Indicators like crossing the foul line and such

MAX is FFF would be in there

Some alleys use dots instead but same function

[sleek hollow]

ok, so 4 across the top then

[azure talon]

yes

ok here's an example of a single frame

[azure talon]

just an fyi I do function before looks. but if you think it should be written different i'm all eyes.
I'm not sure how to call the right widget just yet. In tk I know how to index through it, just sure about this yet though.

[sleek hollow]

but now you can instantiate the BowlingFrame 10 times to create a bowler's frames

it's very basic for now

but each of these boxes can be populated with values

this isn't super optimized either though since I just wanted to get an example up and running

[azure talon]

first i get things to work before worring about other stuff really.

[sleek hollow]

this is without any sort of styling, but it works

[azure talon]

looks good. just thinking.

You don't have to write it but thinking.
So I can add a name box before, cycle it 10 times then a total box after.
PySide is differnt way of thinking for sure.

[sleek hollow]

yup, exactly

if you store those 10 "BowlingFrames" in a list, and you write a method that lets you fetch the value, then that makes it very easy to get the total

loop through all your BowlingFrames, call the get_value method, store results

[solid frigate]

why not call it that?

ping me btw

Is this on a Windows tablet? @solid frigate

Calling it that is effectively adding those to every BoxLayout, you'll want to name/create your own.

That kv loaded multiple times would be something to look at too, is your main.py as shown? Or are you loading it too

[solid frigate]

whaaaat

its on a windows laptop

the first code is in main.py and the secound is in neuralrandom.kv

there is no other code parts

[azure talon]

Thanks for your time today. One more thing.
In tk there's a hiarchy of putting things into place. Make a frame put a button ro funtion into said frame.
For PySide, is there a link to something that would explaine it better? Everything I see shows how to make each thing but nothing structured. I might be bad at google. lol

Does running that have the same issue?

[sleek hollow]

There's one additional thing to keep track of, and that's layouts

widgets (like buttons, sliders, labels) can be added directly to other widgets/parents (and this is similar to how tkinter does place), or you can create a layout that sits inside a window or another layout. Some widgets also act as containers like a Frame would in tkinter. QWidget, QFrame, QGroupbox, and there's a few others. These can have layouts set to them

[azure talon]

ok, I thought as much. shouldn't be to hard to figure out then.

[sleek hollow]

This site is probably the best free resource you'll find

[azure talon]

wonderful

one look already seeing the answers. Thanks again

[solid frigate]

apperntly the issue is with the library

its not fit for the newer version of python i have😅

[tribal path]

Which version? Or is it some Spyder quirk

@solid frigate kivy's latest release was with 3.12 support so shouldn't be that

[solid frigate]

u set the version in the code

i got it 1.9

and i got latest version of phthon

ill debug it tmrw

[tribal path]

If you were using a 1.x yea would move to a newer version -
the kivy require is a minimum check (and really of much use anymore)

[solid frigate]

its cuz its not always compatible with older phones

[empty aspen]

Are you still working on this? I have to say, @sleek hollow is basically saying exactly what I was thinking in regard to separation of concern and writing custom tkinter widgets that are subclasses of the already available widgets, but I'll expand a little on their point. @sleek hollow Can feel free to correct me if I am wrong here on anything as I am self taught and sometimes have little things I have missed but here is my two cents.

So in tkinter, just as there is an Entry(), or a Button() widget, there could be a BowlingScoreCard() widget that has whatever abilities you give it, for example:

score_card = BowlingScoreCard(['Bruse', 'kyle' ,'Alex', 'Steve'], <anything else you need to pass>)
score_card.update(player1, next_frame, some_bowling_thing)
score_card.next_turn(....)
#Or something relevant lol I don't know much about bowling but you get the idea I'm sure.

That way your custom widget is designed to do exactly what you need for your specific purpose and you have fine control over every aspect including adding numbers/symbols to the screen at the correct players frame, updating colors (you inherit the parent widgets method so if you use Frame() for example you can do everything a Frame() object can do plus any other abilities you add. Then you simply create an instance of the BowlingScoreCard() (or whatever it actually is lol) for each game.

This also allows you to write all the logic with no coupling to the UI as the GUI just displays data how you tell it, and the logic module handles creating that data. This will make everything a million times easier for you to work with. Let me know if you want some examples.

[azure talon]

Thank you. So cleaning up the code is great and all but the issue is the display not showing everything with each click of the button.
I'm sure that the code can be a lot cleaner though. 😄

[empty aspen]

I don't mean just cleaning it up, I mean refactoring it to use subclasses. That alone could solve the problem of the display becasue it prevents things from covering each other thus uninentionally hiding things. If that makes sense lol

[azure talon]

oh, it does a little. I'm still not good at working with classes.

[empty aspen]

Yeah this is the perfect way to learn. Tkinter is meant to be used with classes in my opion. It seems complicated but it is not and it is very worth it and also sometimes just needs to be explained the right way for the specific person learning them.

[azure talon]

For sure. I like TK. I tried learning QT today and it hurts my brain. lol

[empty aspen]

Lol yeah I prefer tk for sure.. Here I found you a quick example

[sleek hollow]

Yeah, you're absolutely right about how/why you would subclass a widget. tk.Frame is great for organizing a smaller reusable collection of widgets. That being said, there's no way to be sure what's causing the frames to pop in and out of visibility without some serious refactoring and testing

which is why I still say if you're going to take the time to refactor, you might as well use that opportunity to switch to PyQt

[azure talon]

my prob with PyQt is moving data around isn't the same and hard for me to grasp.
We can take this aside if you want to see what I've done with PySide6?

[sleek hollow]

Sure. I'd say to take it slow in the beginning if you aren't already

[azure talon]

I'm trying to put out the demo this weekend of something to look at and what not.

Just some knowledge I just don't have.
Say I build out the same screen by making a class for each frame and iterate it 10 times. How do I update the right frame info when updating the screen. I'm sure it's an easy thing, just don't know. Like do I have to point to a class[i] then the dict ect. Doesn't feel right. ect. To new at it.

[empty aspen]

Ok I need to ask a question.. is frame also a bowling term? lol

[azure talon]

oh sorry. lol yes.

[empty aspen]

haha ok I was having a hard time figuring out what was being represented there lol

[azure talon]

each round of turns payed by each bowler is called a frame, or bowled frame

[empty aspen]

man.. it had to be the same name as a widget lol

[azure talon]

lol i think I names more of widgets well enough thus far. lol

although a name like frame_labels.... not exactly genius

[empty aspen]

lol naming is the worst in GUIs. How are we allowed to show code here? Can we show screen recording of GUIs or is that not allowed? Sorry i have not used discord much

[azure talon]

back tick*3 at before and after your code if it's not too long.

[sleek hollow]

You're absolutely right with this. You can store your bowling frame widgets in a list and access them with [i]

so if I created a bowling frame widget, I could write a method for adding the latest bowl

if I had a variable that kept track of the overall current frame, then I could just feed that information into my bowling frame list

this is pseudocode, but it would look something like this

self.bowling_frames[self.current_frame].bowl(5)

it could even go a step further with keeping track of the player too

[azure talon]

So I already have them as they are in a list. When I call the class to populate so have to call the class when updating or within the class update a main frame class dict?

[sleek hollow]

self.bowling_frames[self.current_bowler][self.current_frame].bowl(5)

[azure talon]

my code already does that

I'm sure i'm not understanding working with classes in the setup part.

[sleek hollow]

it depends how granular you get with your classes. I think the important bits are

A single frame of bowling (contains numbers, fouls, totals)
10 frames of bowling for a single bowler (10 instances of your bowling frames)
An entire game board (10 frames created per bowler)

You can handle all the actual gameplay value updating from the overall game board class (or you could create one more class that acts as a "manager")

not quite the same setup, but here's an example of one of my UI that I use for exporting animation data

This is defined with one class

called a Clip

[azure talon]

this same is 4 bowlers but can be up to 12 average 6 bowlers

[sleek hollow]

This is my ClipManager class. It's responsible for keeping track of how many clips I have, and it can fetch all the data from them

[empty aspen]

how much functionality do each one of these litte sub frame have? Like the are dynamically updated right?

[azure talon]

they are

@sleek hollow you are awesome. 😄 I bow to you and @empty aspen knowledge.

[sleek hollow]

Definitely don't hardcode it to a specific number of bowlers. If it works for 2 bowlers, it should theoretically work for 100 bowlers

[azure talon]

I'm not hard coding to any number. I import the number and names.

[sleek hollow]

QScrollArea widget will be useful if there's many bowlers and you don't have space to display them all at once

[sleek hollow]

That's what I use here

[azure talon]

yea, that's a later thing as for now it'll only be 6 bowlers till I get all functions working.

I have a scroll function on the main screen that sets everything up.

[sleek hollow]

you should write all your bowling logic "in a vacuum". Then it's up to the UI to know what to do with that information

like calculating a frame of bowling. You should have a function that can take in values, and calculate the score

it doesn't matter if you use a UI or not, it should take in values, and return a score

[azure talon]

I don't know if you seen the full code or not.

[sleek hollow]

then it's up to the UI to feed it the values, then take the output of that function and display it

[azure talon]

I do have an update function

[sleek hollow]

but from what you shared last time, it was very directly connected to your UI

you need to write the bowling logic separate from the UI

[azure talon]

right. I understand what you are saying

run it in it's own class.

[sleek hollow]

just take a moment to think about all bowling logic that you'll need

think about inputs and outputs

I find it really helps to write "stub" functions as little placeholders

[azure talon]

should I move them to a separate py and import it or same but separate by class?

[sleek hollow]

up to you

theoretically the bowling logic should be so airtight that you could create a separate bowling program using that same class

like if you wanted a CLI version of it

keep it as decoupled as possible

[azure talon]

ok

[worthy lotus]

how do i make python apps with interfaces

i want to make an adventure game but idk how

like ik how to make one that can be used via terminal

[empty aspen]

Thats what I was going to say. I write a class so it just creates data and then I can pass it to either a cli or a GUI and it works the same.

[lament yacht]

Does anyone here use PySimpleGui? If so does anyone have a good tutorial on how to use it with OOP?

[empty aspen]

This is what I learned tkinter with years ago.. it took me a while to undertsand this but once I did it helped a lot.. this example is a bit old and its from John Greyson's book Python and Tkinter Programming (but updated for python 3). Its just a learning script but it shows the power of what @sleek hollow and I are talking about as far as subclassing. The separation of concerns could be better but it's not the point of the example.

https://paste.pythondiscord.com/D3XA

[sleek hollow]

A lot of the power of these classes also comes from writing methods to interact with the data within that class

[empty aspen]

yes

[sleek hollow]

so a bowling frame class makes sense to have methods like "bowl()" and "get_total()"

[azure talon]

I think this is all great but I still missing the OG understanding.
Like the main screen should be the top frame and the bottom 2 frames.
Then I build a game class to put into the middle as that can change.
How do I put that into that middle frame.
Do I create a master frame in the class then, I guess add that frame into the main screen frame? or not do that?
I get classing out functions.

[empty aspen]

honestly if it were me, I would write the entire program with no GUI. Once I had a program that could produce the data I needed, I would start to create a custom widget for those little sub squares that are dynamically updated. I would write them to be ready to handle displaying the data they are passed. Then I would create a dashboard style layout with frames. I would pack the instances of my custom widget into the dashboard sections. See how I create my frames (using a custom Dashboard class I wrote), that allows me to just pack the custom Tree viewer I wrote? I wrote them completely separately, but they just plug in to each other.

[azure talon]

It works with no gui. lol

[empty aspen]

so then can you get all the non GUI code in to a separate file?

[azure talon]

I mean it's 25 lines but yea. It normally is as all that data comes in externally.

I only put it in this file cause the GUI was messing up.

[empty aspen]

oh the non GUI code is only 25 lines?

[azure talon]

Not sure if you saw the code or not.
lines 320 to 523 come in as a data point conisting of 4 dict's.
Not large though.
Then line 525 to 562 is the update I have to update the gui. The gui is 300 lines.

so normally 320 - 523 are not there.

Keep in mind I have them in their own class and not each def as a class.

[empty aspen]

Ok. I did see the code and i have it open here but I looked at it from a "why are the frames jumping" perspective as I realized I don't know anything about bowling lol

[azure talon]

lol Well if there's a bowling center any where near you, you should try it, it's fun.
There's 2 types, 5-pin and 10-pin. If I was coding 10-pin, I would be done forever ago.

[empty aspen]

lol I haven't done it since I was a kid. I started seeing things like turkey and I was like.. hmm yeah I know nothing lol

[azure talon]

do you watch or play any sports?

[empty aspen]

I do jiu-jitsu and watch football

[azure talon]

lol well I'll make it super simple as I can.
Each ball is a down and each frame is a qtr. (american football)
Each bowler gets up to 3 balls to knock them all down.
if all in 1 - strike
if all with 2 - spare
ball 3 is ball 3.
If you get a strike the next 2 balls count to that frame score. so gotta look back.
if spare next ball counts to that frame.
After each blower gets a turn a new frame starts.
Then add skip functions and incase someone is late or in the bathroom. Reset in case the pins don't setup correctly.

hitting throw ball buton simulates the ball crossing the ball senor and hitting or missing the pins.

[empty aspen]

ohh ok i see

ok so these functiions are your non gui functions

[azure talon]

Yea

so normally they come in like this:

[empty aspen]

I was seeing frame and not realizng that lol

[azure talon]

data[bowler#,frame#,Ball][ball value 0,0,0][symbol 0,0,0,0] the forth is tracking if a ball is thrown as you can't skip after the first ball.

This goes into the update at the bottom and updates the ui up top.

[empty aspen]

ok and tell me again the main use for this?

like tracking actual games, right?

[azure talon]

Yes.
Trying to get more people to play bowing. So setting up lawn bowling at events and bowling at events indoors where people can just come play and find enjoyment in the game to come out the bowling centers near by.

[empty aspen]

ohh cool

[azure talon]

So I already build the physical bowling setup to detect pin drop and return the balls. just need to get the screen to work.
there's a laptop setup to enter names and what not, send it to the lane where there's monitors of different size, doing this on the cheap.

[empty aspen]

its cool tho haha

[azure talon]

I think the frames are resizing, if I can get them to stay in place one in place. That would be the real goal.

frame frames. lol

[empty aspen]

yes.. which is why you need a custom widget

[azure talon]

aka don't resize once there.

[empty aspen]

so notice how the buttons on the calculator dont do that?

[azure talon]

well I wanted to do a set size but on differn't screens it looks really messed up.

[empty aspen]

they are each containerized on their own frame

and likely group onto another frame all together

[azure talon]

right and I thought I kind of set it up like that as it builds the name frame then the game frame then total and set weights to each in the grid setup.

[empty aspen]

yeah I see what you are saying

[azure talon]

so I'm just not kowledgable enough for sure.

[empty aspen]

I tend to use pack() and let them expand

sometimes certain apps are design to not be resized also

[azure talon]

So I tried packing everything. It was a mess. grid in the pack got the results so much easier for the most part. 😄

[empty aspen]

yeah haha you have to manage that or it will yell at you lol

[azure talon]

well it looks great. till it fails. :S

[empty aspen]

ok so those little sub squares are "bowling_frames" and they are tracking the results of each "ball" of each turn of each player.. yeah?

[azure talon]

Yes.
top left to track going over the foul line with a max output FFF.
then ball 1, 2, 3

[empty aspen]

oh so that is why there are 4 on top, and the one on bottom?

[azure talon]

yup

the bottom is the earned total plus preivous frames completed.

[empty aspen]

so one thing with the alignment to not change is that the text can't cause the parent widget (where you packed your label) to change size

[azure talon]

ok

Not sure if you saw my message, but we can take this to a vid call if you like. Might be faster. :S

[empty aspen]

I did not. I actually have to run to pick up my daughter now, but I will look at this more when i am back

[azure talon]

hit me up with an @ when you'd like to chat more.
same goes with @sleek hollow

[empty aspen]

for sure ttys

[azure talon]

be safe

[sharp nest]

Does someone know a good module for prompting in python? I'm currently using InquirerPy and I love it, the only thing is that it taskes really long to detect keyboard presses while in a prompt. See some testcode below:

# import libraries
from InquirerPy import inquirer

# create basic prompt
prompt_answer = inquirer.text(
    message="test", default="", mandatory=True,
)

# define function to handle escape key
@prompt_answer.register_kb("escape")
def _handle_escape(event):
    print("escape pressed")
    event.app.exit(result="escape pressed")


prompt_answer.execute()

InquirerPy is based on PyInquirer, but this module is a bit dated and doesn't even work on python 3.11, which in turn is based on prompt_tools. Can somebody help fixing this slow keybroard press detection or do I have to use another module instead of InquirerPy. If so, which one do you recommend?
P.S. I don't really want to a GUI, just a little bit more shiny than plaintext in the python console.
Thanks in advance

[dire barn]

How exactly do you define "shiny", i.e. what is input() missing?

[sharp nest]

https://inquirerpy.readthedocs.io/en/latest/pages/prompts/list.html If you look at the top of this site, you can see an example of a select menu. This is something you can't do really easily with input() I thing. With this module you can also prompt a check list etc.

[dire barn]

Right, but you are talking about text input, are you not?

[sharp nest]

@dire barn text input but also menus where you can select what you want to do

[sharp nest]

This is an example of a menu using PyInquirer

[sharp nest]

# import libraries
from InquirerPy import inquirer
from InquirerPy.base.control import Choice
import time
import keyboard
from threading import Thread


def detect_key_press():
    global start_time
    while not keyboard.is_pressed('escape'):
        pass
    start_time = time.time()


# create basic prompt
prompt_answer = inquirer.select(
    message="select an action",
    choices=[
        Choice("add", "Add"),
        Choice("remove", "Remove"),
        Choice("edit", "Edit"),
        Choice("print", "Print"),
        Choice("settings", "Settings"),
        Choice("help", "Help"),
        Choice("quit", "Quit"),
    ],
)


# define function to handle escape key
@prompt_answer.register_kb("escape")
def _handle_escape(event):
    # print how long it took to detect the escape key
    global start_time
    print(f"escape key detected after {time.time() - start_time} seconds")
    print("escape pressed")
    event.app.exit(result="escape pressed")


start_time = 0
thread = Thread(target=detect_key_press)
thread.start()

prompt_answer.execute()

Using the code above I time how long it takes to detect the escape key and on average it was like 1.5 seconds. Is there maybe a way I can use PyInquirer and threading in combination with each other? The thing is that I still want to use event.app.exit(result="escape pressed") and that it won't work without the decorator.

[sharp nest]

I did some more testing and the problem only occurs when using escape. There are maybe some other keys but I didn't find any

[dire barn]

This is because of how special keys work in a terminal. If the library for example wants to react to arrow keys, those are given to the program as a sequence of several keys, starting with "escape". To know whether you meant to press escape, or something else follows to mean a special key, the library has to wait for a bit. But 1½ seconds seems excessive. Maybe this timeout is configurable?

Looks like InquirerPy uses prompt-toolkit, which has a ttimeoutlen option

[lament yacht]

so I need help using tkinter with custom tkinter, I am trying to center these grid like view, but to no avail, its impossible for me.

class Section(tk.Frame):
    def __init__(self, master=None, title="", **kwargs):
        super().__init__(master, bd=2, relief=tk.GROOVE, **kwargs)
        self.title = title
        self.info_var = tk.StringVar(value=f"{title}: No data")

        title_label = tk.Label(self, text=title, font=('Helvetica', 14, 'bold'), justify='center', pady=10)
        title_label.grid(row=0, column=0, columnspan=2)  # Place the title label in the first row, spanning both columns

        info_label = tk.Label(self, textvariable=self.info_var, justify='left', padx=10, pady=10)
        info_label.grid(row=1, column=0, columnspan=2)  # Place the info label in the second row, spanning both columns

        # Configure rows and columns to expand and fill available space
        self.grid_rowconfigure(0, weight=1)
        self.grid_rowconfigure(1, weight=1)
        self.grid_columnconfigure(0, weight=1)
        self.grid_columnconfigure(1, weight=1)

    def update_info(self, new_info):
        self.info_var.set(new_info)

    def handle_event(self):
        # Add your event handling logic here
        pass

class Dashboard(tk.Frame):
    def __init__(self, master=None, sections=[], **kwargs):
        super().__init__(master, **kwargs)
        self.sections = sections
        self.exit_event = threading.Event()

        # Arrange sections in a 2x2 grid
        for i, section in enumerate(self.sections):
            row = i // 2
            col = i % 2
            section.grid(row=row + 2, column=col, padx=10, pady=10, sticky="nsew")  # Make the sections expand and fill their cells

        exit_button = tk.Button(self, text='Exit', command=self.exit)
        exit_button.grid(row=4, column=0, columnspan=2, pady=10, sticky="nsew")  # Make the button expand and fill its cell

        for i in range(5):
            self.grid_rowconfigure(i, weight=1)
            self.grid_columnconfigure(i, weight=1)

    def exit(self):
        self.exit_event.set()
        self.master.destroy()

class MyAppGrid(CTk):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        on_duty_section = OnDutySection(self)
        apparatus_section = ApparatusSection(self)
        incidents_section = IncidentsSection(self)
        responders_section = RespondersSection(self)
        self.sections = [on_duty_section, apparatus_section, incidents_section, responders_section]
        self.geometry('600x400')

        dashboard = Dashboard(self, sections=[on_duty_section, apparatus_section, incidents_section, responders_section])
        threading.Thread(target=self.event_loop, daemon=True).start()

    def event_loop(self):
        while True:
            for section in self.sections:
                asyncio.run_coroutine_threadsafe(self.fetch_data(section), self.event_loop)
                section.handle_event()  # Simulate handling section-specific events
                time.sleep(1)  # Simulate fetching data every second

    async def fetch_data(self, section):
        # Simulate fetching data asynchronously (replace with actual logic)
        await asyncio.sleep(1)
        new_info = f"{section.title}: Updated data at {time.strftime('%H:%M:%S')}"
        section.update_info(new_info)

So I omitted some codes since I don't think they're relevant

[azure talon]

@sleek hollow & @empty aspen I figured it out. in the label creation, width = value. it sets the number of expected charictors. This prevented the resizing to occure.

some flashing occurs but it's very minimal/

[azure talon]

@sleek hollow & @empty aspen Still would love some help with the code cleanup ideas. 😄

[sharp nest]

Thank you I'm going to look it up

[sharp nest]

I found this in application.py in prompt_toolkit. Could it be that both these timeouts are added?

[sleek lion]

Anyone here knows why PySimpleGUI does not let you check a window size and position before closing it?

        while True:
            event, values = self.window.read()
            if event == PySimpleGUI.WIN_CLOSED:
                print(self.window.size)
                self.save_window_config()  # Store the window size to the config file
                break
            elif event == 'Add Note':
                self.add_note()
        # Close the window after saving the configuration
        self.window.close()

This print never works, the error is:

[lament yacht]

My own opinion: but I obv cant answer this, since im a beginner in making UIs, i think using customtkinter is better

[dire barn]

The way I understand it that should only be the case if you have a mapping for "escape", but also one for "escape, followed by the letter g" or something like that

[sharp nest]

Yes I think that too. Not using escape as exit key then

[sleek lion]

I've always used PySide which to be honest is a lot superior, but for the funsies of learning I tried to create an app with PySimpleGUI and I'm quite disappointed haha

[split marsh]

Can someone help me with this thing? pip install pyside6 but the pyside6-uic is not working.

[misty canopy]

probably WIN_CLOSED is emitted when a window gets closed, at which point it's too late to request its size and stuff.

[sleek lion]

that's my guess, so I've checked in the documentation and there is a flag to enable events on attempted closing of the windows, which triggers the saving but now it do not close the window as it overrides the closing, we have to implement our own closing. What a mess for a "simple" library hahaha

[azure talon]

@sleek hollow & @empty aspen
So I tried making them classes and now I've got a new list of visual issues. 😄 Mostly a sizing issue:

Anyone else can see what I'm missing:
https://paste.pythondiscord.com/QEJA

Got this:

Should be this:

I've also made a few changes to my test code for the og display function here:
https://paste.pythondiscord.com/KQIA

[sleek lion]

I ended up doing the same program twitce, with pysimpleguy and with pyside6, all it took has been around 5 hours. But I am going to stick with the pyside6 version, it's a lot more stable and with less weird errors. In case anyone wonders how both frameworks adapt to a dynamic layout, both files are in: https://paste.pythondiscord.com/TPTA
I am sure it can be improved a lot, after all I am just experimenting and having fun with it.

[bright spade]

Hi ! did anyone have some competences with PyQt5 ?

[azure talon]

Not a good one. 😄

[sleek lion]

I used to... 5 years ago

what do u need?

[bright spade]

I just have a layout with one column and I have no idea how I can put two columns next to each other 😅

It's like this for the moment I want to double the number of column but I can't do it lol

Would you like to take a look at my code?

[sleek lion]

something like this?

[bright spade]

more like that

[sleek lion]

I am going to assume you are using a QtWidgets.QVBoxLayout for that one? you would have to use a Grid Layout

[bright spade]

in width

I use a layout actually x)

[sleek lion]

not sure I understand what's the issue then

if you are using a grid, adding a new column is trivial

[bright spade]

yes I know it's easy but I just can't find the trick 🤣

[sleek lion]

the tricky part comes if you allow the window to be resizable and adapt the content to the new size of the window xd

Well, layout.addWidget(widget/button/element/whatever, row, col, 1, 1)

that's how you control in which column you set the element up

[bright spade]

So I don't need this ?

self.right_column_layout.addLayout(self.fuel_row) self.right_column_layout.addLayout(self.tyre_row) self.right_column_layout.addLayout(self.first_row) self.right_column_layout.addLayout(self.second_row) self.right_column_layout.addLayout(self.third_row)

[sleek lion]

When you add elements you can specify "where"

instead of just adding and defaulting to "next one", which seems to be what you are doing

controlling the position of the row and column will give you more control

albeit a bit more complex

[bright spade]

wait and see how it all turns out and make fun of me knowingly 😅

[sleek lion]

well... if it works it works, but you should read https://doc.qt.io/qt-6/qgridlayout.html

[bright spade]

thx

[sleek lion]

because as I was guessing, you are using a QVBoxLayout, it's there in your 5th line haha

[bright spade]

[sleek hollow]

I've always struggled with dynamic sizing in tkinter 😦

[azure talon]

yea but if they are not in classes it's fine. 😛

[sleek hollow]

also avoid multi-variables like this

you should use a dict or list to represent this

[azure talon]

sure but I see that more as a code cleanup later then anything, as it's handy when finding errors upfront. For me anyway

[sleek hollow]

if anything, more variables is harder to debug

[azure talon]

Not for this brain. If ball1 doesn't update I can locate the issue quickly. :S

[sleek hollow]

I can show you an example of how I would structure it in pyqt

[azure talon]

But I do understand what you mean

[sleek hollow]

from PyQt5 import QtWidgets


class BowlFrame(QtWidgets.QFrame):

    SIZE = 128, 128

    def __init__(self):
        super().__init__()
        self.setFrameStyle(QtWidgets.QFrame.Box)
        self.setFixedSize(*BowlFrame.SIZE)


class BowlerFrames(QtWidgets.QFrame):

    NUM_FRAMES = 10

    def __init__(self, bowler_name='Unknown'):
        super().__init__()
        self.setFrameStyle(QtWidgets.QFrame.Box)
        main_layout = QtWidgets.QHBoxLayout()
        self.setLayout(main_layout)
        self.bowler_name = bowler_name
        self.bowler_lbl = QtWidgets.QLabel(bowler_name)
        main_layout.addWidget(self.bowler_lbl)
        self.frames = []

        for i in range(BowlerFrames.NUM_FRAMES):
            frame = BowlFrame()
            self.frames.append(frame)
            main_layout.addWidget(frame)

class LaneWindow(QtWidgets.QDialog):

    def __init__(self):
        super().__init__()
        self.main_layout = QtWidgets.QVBoxLayout(self)
        self.bowler_frames = []
        for bowler in ['Timmy', 'Alex', 'Sally']:
            bowler_frame = BowlerFrames(bowler)
            self.bowler_frames.append(bowler_frame)
            self.main_layout.addWidget(bowler_frame)


app = QtWidgets.QApplication([])
win = LaneWindow()
win.show()
app.exec()

it's missing the internal widgets, but the structure is here

once this structure is in place, it's now simpler to go in and simply edit the internal widgets. If I modify the BowlingFrame class, I know the placement of this widget is going to stay the same

I often will lay out my UI like this as a first pass "sketch", and then go fill things in

QFrame with Box style is a great way to visualize your widgets (since otherwise everything is "invisible" and it can be hard to see exactly what you're doing)

some more modifications. Now each frame is capable of displaying 3 bowls, and room for a total

[azure talon]

(need 4 across the top.

[sleek hollow]

the actually functionality isn't implemented, but that's ok, we're just making sure it's capable of displaying the values

ahh right

[azure talon]

but I get you

[sleek hollow]

but yes, I'm using a loop, I can just change the loop from 3 to 4

instead of adding a new variable

easy change

[azure talon]

Seems easier then my brain computing it.

[sleek hollow]

more modifications, little by little

[azure talon]

Want to see what i got going on so far?
can do a screen share meeting thing if you like.

[sleek hollow]

sorry I can't

I'm not nearly as well versed in tkinter tbh

[azure talon]

I mean with QT

Cause I am trying

[sleek hollow]

if it's anything like your tkinter code, part of the issue is you're still cramming too much into a single class

you need to compartmentalize/encapsulate

my GUI doesn't care where the data is coming from

it just needs to know "set this label to this value"

[azure talon]

So I have a lane entry class for reasons then a main screen class then starting the bowling game it's self in

[sleek hollow]

is lane entry what happens before the game starts?

[azure talon]

yes cause there's differnt bowling game types that can populate the main display region. For not, just getting the base working before adding other types

So It should always show this if no game is one, but changed to blue.

Then a call from the server with game type, bowler names and stats like averages and what not will be sent over to provide the data needed to start a game

[sleek hollow]

In my example, I'm using the LaneWindow class to display the information during a game of bowling. I would have another class eventually that would hold that class and has all the additional information surrounding it

you can use a "QStackedLayout" to hold multiple "screens" if you want to choose what to bring forward and display to the user

you could have a welcome screen/login screen/enter names screen or whatever other "screens" you want to come up with

[azure talon]

well all that last part gets sent, don't need a keyboard (physical or on screen) at the lanes. Just receive the data and populate

[sleek hollow]

how do the names get entered? During like a registration with the front desk?

[azure talon]

You bet

[sleek hollow]

ahh ok, nice

[azure talon]

when the lane system starts I need to know the lane before connecting to the reg desk:

[sleek hollow]

yeah, that would be a perfect use of a QStackedLayout then

[azure talon]

Once start is hit, generate the blank lane screen to wait till a game is sent

again can call and teach, less typing. lol

[sleek hollow]

If you use QMainWindow, it also has a "centralWidget"

[azure talon]

ok

[sleek hollow]

so instead of QStackedLayout, you can use QStackedWidget as your main widget

and then swap in the widget you want to display

[azure talon]

would it be better to load the main screen, popup the lane entry as it only needs to be done once, then the result back to a vaiable in the main to start the call to the reg desk that it's ready?

[sleek hollow]

yeah that would be fine, you could destroy that widget once you've retrieved its value

that would be a perfect use for a signal

[azure talon]

do I do something like:
Main_Screen.lane_id = lane_id
from the lane select. Not sure how how to send it over. The class construction for QT is a little different and I think it confuses me.

There's a single piece of info I'm missing in my brain to connect all the dots. Like a mini gap

[sleek hollow]

I can show you a basic example of that but then I have to get going

[azure talon]

appreciated

Please don't do too much.

this is the gap I'm missing. Obviously the arrow is where I'm failing

    def start_main(self):
        lane_number = self.lane_number_entry.text()
        # Main_Screen 'variable :lane_id' = lane_number <---
        self.destroy()
        
        # Put window code here
        

class Main_Screen(QWidget, Ui_Main_Lane_Screen):
    def __init__(self, lane_id):
        super().__init__()
        self.setupUi(self)
        self.lane_id = lane_id
        self.lane_check = False
        
        if self.lane_check == False:
            print(self.lane_check)
            Lane_Select().show()
            self.lane_check = True
            print(self.lane_id)

[sleek hollow]

https://paste.pythondiscord.com/NOCA

alright try running just this

[azure talon]

you do too much, I owe you a drink

[sleek hollow]

it will start with just this entry. I wasn't going to build a whole num pad, haha. Type in a lane number here

Then it will display your bowler names with the current lane number at the top

[sleek hollow]

It's good practice for me as well 🙂

There's definitely still some missing connections like setting up the correct bowler names, and all the helpful methods for setting values in the frames, but hopefully this gives you a better idea of how to pass data around

[azure talon]

Thank you again.

[sleek hollow]

Np! Is there anything there you're unsure of?

[azure talon]

Just looking at it now.

[lament yacht]

Yeah me too

[azure talon]

Just to understand.
You set the variable to send:
lane_selected = QtCore.Signal(int) (changed for pyside6)

You emited the signal:
self.lane_selected.emit(lane)

This caught the signal:
self.lane_screen = LaneScreen()
self.lane_select = LaneSelect()

    self.setCentralWidget(self.lane_select)

    self.lane_select.lane_selected.connect(self.on_lane_selected)

So it looked into the lane_select that is equal to the class,
looked at the vairable signal lane_selected
and connected it to def of on_lane to action the data received.

If I'm understanding you.

[sleek hollow]

yup, signals is how data gets passed around in your GUI. It's like using command=... on a tkinter button

in pyqt, most widgets have pre-built signals, like clicked for a button

[azure talon]

command is so much easier for me.
But that helps a lot. I know it functioned kind of the same but how it actions is different for sure.

[sleek hollow]

but here, I created a custom signal for the lane select widget, which gets emitted when a lane is selected

self.some_button.clicked.connect(self.some_method) would be the setup for a button in pyqt

[azure talon]

I like this cause when I send data over, I can parse it into different variables to be grabbed but the update func.

[sleek hollow]

command is nice in tkinter since you can assign a command to it in the same line that you create the button

[azure talon]

yea I got buttons pretty good.

[sleek hollow]

in pyqt, things tend to be very verbose.You need a lot more lines, even to do seemingly simple things

but that also means you have far more control over every little thing

[azure talon]

yea same line simple functions is like wearing socks in boots, feels good.

[sleek hollow]

in tkinter, you can only have a single command tied to a button though

[azure talon]

ha ha well they both have their advanages like you mentions before.

[sleek hollow]

in pyqt, I could connect the button to many different methods

signals are a good way for the main window to know when certain things have happened in the ui

[azure talon]

for sure.

[sleek hollow]

here, the main window is waiting to receive the "lane_changed" signal to know when it is meant to display the next screen

[azure talon]

in tk you can do an active variable to act that way as well. But I knind of don't like them as you always need a tick happening in that frame. Get's flashy if too much is happening on the screen

[sleek hollow]

active variable?

like StringVar?

[azure talon]

yea I know the name, one sec.

yes

[sleek hollow]

there's something similar in pyqt but it's mostly meant for larger data

Model/View

[azure talon]

yea, I don't really use it myself. I never saw a problem with just updating the text in a label when I need it. More control then sending a signal all around.

[sleek hollow]

a good example of where you might want to set up a signal would be the total score for a frame

your actual Bowling class would be responsible for updating each bowl, but you could emit a signal every time a bowl occurs to update the total score for that frame

you could emit a signal every time a frame ends, so it knows to move onto the next bowler

it's really nice to just emit signals when certain things occur, and then it's up to you to connect up your UI to determine what widgets care about the data that was just emitted

[azure talon]

Just opened a box of more questions. lol
I can incorporate it into my existing code and get it to work, that's great. 😄

[sleek hollow]

Take the code I gave you and just play around with it for a bit. Try and change some values, see what happens. Use it as a sandbox for testing stuff until you really feel like you have the hang of things

then you can focus on trying to combine it or integrate it with your other code

[azure talon]

Oh I am. Peicing it to gether to functions as I want.
Gotta add a few more things to it, that'll help understand as well.

[sleek lion]

Weekend project using PySide6. It can be improved a lot, but for 6 hours or so, I am happy.
https://github.com/Aens/Unmemorize/tree/master

I appreciate feedback. (Eventually I will use a database instead of txt files 🤣 don't worry, this was just for funsies)

[lament yacht]

okay, I've gotten the grid like system which is perfect, however I need help now to expand these boxes so each box covers a side of the window:

ex.

class RespondersSection(CTkFrame):
    def __init__(self,master):
        super().__init__(master)
        self.master = master
        self.grid_columnconfigure(0, weight=1)
        self.title = "Responders"
        #self.pack(pady=20,padx=20)
        self.grid(row=1, column=1, padx=20, pady=(10,10))
        self.width = 100
        self.height = 100
        #self.anchor(customtkinter.S)

class IncidentsSection(CTkFrame):
    def __init__(self,master):
        super().__init__(master)
        self.master = master
        self.grid_columnconfigure(0, weight=1)
        self.title = "Incidents/Calls"
        #self.pack(pady=20,padx=20)
        self.grid(row=0, column=1, padx=20, pady=(10,10))
        self.width = 100
        self.height = 100
        #self.anchor(customtkinter.S)

What can I do to ezpand this?

[lament yacht]

app:

class App(CTk):
    def __init__(self,*args,**kwargs):
        super().__init__(*args,**kwargs)
        self.title("FD Dashboard")
        self.geometry("600x400")
        OnDutySection(self)
        ApparatusSection(self)
        RespondersSection(self)
        IncidentsSection(self)
        self.anchor(customtkinter.CENTER)





if __name__ == "__main__":
    customtkinter.set_appearance_mode("dark")
    customtkinter.set_default_color_theme("dark-blue")
    app = App()
    app.mainloop()

[azure talon]

cause that are custom size, you are limiting them to what you can do with them. try adding to the grid

sticky = 'nsew'

But top right being NE and bottom left being SW... ect

[unique flare]

guys i am trying to install tkdesigner but i keep running into issues with pillow

i have tried using pip install tkdesigner Pillow==10.2.0 which gets the job done but gives this module error with urllib3. i have tried uninstalling and installing urllib3 but that didnt fix it either

[azure talon]

yea, I never got around that either.

[tribal path]

Either see if a version <2 of urllib3 works with 3.12 or use python 3.11 until tk designer updates to support v2.x

[unique flare]

i used python 3.11 as well

gave the same issue

that pillow 8.4.0 doesn't support 3.11

and installing a lowe version of urllib3 didnt fix the issue either

[unique flare]

it gave that urllib3.packages.isx.moves module not found error like on this screenshot i mentioned

i just downgraded to python 3.10 and that seemed to fix the issue for now

[tribal path]

Had presumed the sticking point was more urllib3 (with a presumption that <2 wouldn't be supported on 3.12).

If the designer is also reliant/pinned on an older pillow (<9.2.0 perhaps) then yea will need to stick to a supported python and await updates

[lament yacht]

okay

[flint marlin]

trying to do the command of "Status Bar" to toggle the status bar on the bottom like in notepad but when the frame.grid_remove() is called in else condition it didnt work
it worked when doing it manually without the toggle

initial call

after the command is pressed

class Menus:
    def __init__(self, window, textarea) -> None:
         self.status_bar_toggle = True
         
         self.status_bar()

    def status_bar(self):
        frame = Frame(master=self.window, height=24)
        Label(master=frame, width=24).grid(row=1, column=0)
        Label(master=frame, text="Ln 1, Col 1", relief=GROOVE, justify=LEFT, anchor=W).grid(row=1, column=1, ipadx=40)
        Label(master=frame, text="100%", justify=LEFT, anchor=W).grid(row=1, column=2, ipadx=5)
        Label(master=frame, text="Windows (CRLF)", relief=GROOVE, justify=LEFT, anchor=W).grid(row=1, column=3, ipadx=10)
        Label(master=frame, text="UTF-8", justify=LEFT, anchor=W).grid(row=1, column=4, ipadx=30)
        
        if self.status_bar_toggle:
            self.textarea.insert("1.0", f"status bar toggle set to {self.status_bar_toggle}\n")
            frame.grid(row=1, column=0, sticky=E)
            self.status_bar_toggle = False

        else:
            self.textarea.insert("1.0", f"status bar toggle set to {self.status_bar_toggle}\n")
            frame.grid_remove()
            self.status_bar_toggle = True

the class was called in my other file

[sleek hollow]

It seems excessive to recreate the status bar every time you need to display it. Create it once and store it in an attribute, then use a toggle to show/hide it

[flint marlin]

will do, thank you

[hexed pendant]

what package do I use for UI

[sleek hollow]

You have a few different options. tkinter comes with python already installed so it's a good place for a beginner to jump right in. If you want something more advanced, you can use PyQt

[hexed pendant]

does tkinter come with some restrictions to what I can do?

[sleek hollow]

do you have a specific UI in mind you're trying to make?

[hexed pendant]

not really but I think I would like to start by making like a basic inventory

like a minecraft inventory for example

[sleek hollow]

If you want something with drag/drop support, I'm actually not sure how well tkinter would handle something like that. PyQt has great drag/drop support though. How experienced are you with python already?

[hexed pendant]

eh I honestly dont know where I would put myself ig i'd go with beginner

I know control flow and feel like I have a decent grasp on the basics

[sleek hollow]

have you done any OOP/class coding?

[hexed pendant]

dont think so

[sleek hollow]

I'd start with tkinter then and just focus on a basic UI. Even with experience in pyqt, drag and drop can be a bit tricky to wrap your head around

[hexed pendant]

alright ty I appreciate the help

[brisk mauve]

I do a lot of SQL for work, and I overclock Excel for dumb things coworkers request quick one-and-done projects, but I think I would like to start developing Python scripts that can 1) collect data on a webapp so I don't have to use MS infrastructure to collect data for our various business processes, and 2) quickly work up data with some basic visualizations (think bar graphs) dumped from a SQL query into a csv. Currently use Azure Data Studio for our SQL stuff because it's free, and we use an Azure SQL db for our data storage (cheap, and our datasets are relatively small).

I've dipped a toe into both PyCharm and VSCode, but honestly they just feel clunky to me. I got my start coding back in Visual Basic back when I was in elementary school...so I'm drawn to a more minimal workspace. Anyone have experience with something like neovim? I like how stripped down it is, but I don't want to put up a big customization barrier between me and getting a few quick projects done.

Thoughts on neovim vs Pycharm/VScode for someone who does primarily fullstack data stuff?

[inland wedge]

helix is like neovim with a few better design desicions imo and more built in, ive had it for 1.5 yrs and my config is still like 10 lines of toml. A lot more stable for me than neovim distros

if you need plugins regarding sql, then plugin support is not yet merged

[brisk mauve]

plugins aren't really a big deal for me. If I really need the autocomplete functionality I do my query writing in ADS anyway. Sounds like you'd confirm that a more stripped down editor as an IDE is perfectly viable though. Does helix allow Git integration? I'm currently using Github for company-accessible code like SQL queries used outside my office, etc.

[inland wedge]

yes that was my concern going in but since it supports major protocols like language servers and treesitter it doesnt feel stripped down, it is pretty similar in features to vscode, just with a tui and it is compiled rust not electron. The git integration in helix right now is pretty minimal like showing changes made to a file since last commit in the gutter.

in my mind, it fits quite well in a tui ecosystem so git could be handled by something like lazygit

[pearl dune]

How does this ui design look for an installer and auto updater I made for fun? Made with PYQT5

[digital rose]

I am genuinly surprised that something this beautiful is possible with pyqt. in any case, a UI thing you should perhaps do is that the highlighted option should have brighter text to, well, highlight it

[somber hemlock]

The title UPDATE / INSTALL has slightly more padding than the subtitle. You don't need to make subtitle all caps (it looks kinda cringe when everything is all caps), plus you are already using a slightly gray color (experiment with font weight too) anyways. Desktop shortcut can be a checkbox instead and it will still look good. Btw where is the close / minimize button?

[somber hemlock]

Qt QML is very HTML / CSS like

[sudden elk]

someone knows if and how is it possible with default libraries to draw on screen without any windows? Best if cross-platform (yeah, heard of windows tools but what about linux, mac, bsd and others?)

[sleek hollow]

In general, good UI design is up to the user, not the library

[misty canopy]

"with default libraries" is quite a massive constraint, here.
this supposedly-crossplatform tkinter example works for me on linux: https://stackoverflow.com/a/68443540

[sudden elk]

Tk have problem with possibility to clickthrough...

[sudden elk]

And i have no fear of embedding c/c++ inside python (as long as it won't require additional installations of anything)

[inland wedge]

libadwaita kinda gives you that look out the box

[sudden elk]

Like i'd like to achieve sort of overlay of a custom WM

To loop over pixel 2d array, get or set colors and manually detect clicks (or clickthrough or ignore)

[pearl dune]

sry to anyone who finds this horifying, but the close and minimize buttons had to be traded in to allow for rounded windows. Also I am aware of the padding issue, they both have the same padding in code, making that hard to fix.

[somber hemlock]

If its not a padding issue maybe its a margin issue. Dunno if QML follows the CSS box model

[pearl dune]

yea, but there is none of either

im just gonna role with it as is, might change it in the future

[somber hemlock]

It might have margin by default

[azure talon]

[slim cairn]

I have a scrollable canvas with frame window placed on it. Instead of using scrollbar i am using mousewheel directly and manually updating the yview_scroll of canvas. The problem is that when canvas gets scrolled the frame (inside canvas) do not properly gets scrolled and bottom contents are still hidden.
I can't understand that what is missing to fix this issue.

Here is what i mean:
Left is before scroll and right is after scroll.
(canvas is colored red and frame inside canvas is colored yellow)

This is the updation code: https://paste.pythondiscord.com/OOYA

    def _configure_frame(self, _: Any):
        """self.frame.bind("<Configure>", self._configure_frame)"""
        w, h = self.frame.winfo_reqwidth(), self.frame.winfo_reqheight()
        self._canvas.config(scrollregion=(0, 0, w, h))
        self._canvas.config(width=w)
        self._canvas.config(width=h)

    def _configure_canvas(self, _: Any):
        """self._canvas.bind("<Configure>", self._configure_canvas)"""
        self._canvas.itemconfigure(self.frame_id, width=self._canvas.winfo_width())
        self._canvas.itemconfigure(self.frame_id, height=self._canvas.winfo_height())

    def _on_scroll(self, e):
        """self._canvas.bind("<MouseWheel>", self._on_scroll)"""
        self._canvas.yview_scroll(-(e.delta // 120), "units")

[carmine pulsar]

i want to make a simple spinning wheel, like wheel of names, with probability control and custom colours, it’s possible to make it in python or it is not the best language to create this kind of stuff

and also what is the best module i can use?

[mighty frigate]

best I can't tell you as I only know Qt but it's doable, although it's quite painfull

there's no such component existing so you need to create your own, and you need to draw it yourself

[carmine pulsar]

oh crab

[mighty frigate]

I wouldn't recommend Qt beginners to try to do this as a first project with Qt

[sleek hollow]

Spinning a widget in pyqt sounds paintful

[mighty frigate]

you don't have to actually spin it, only it's representation

[sleek hollow]

property animation?

[mighty frigate]

actually that's a good question

that's not the road I would have take instinctively

[sleek hollow]

I don't think there's any sort of rotation property...

convert widget to pixmap with grab, rotate the pixmap?

[mighty frigate]

you can make a fixed widget and draw it diffrently depending on some state

that's what I would have done

so litteraly drawing everything yourself

and drawing the rotation yourself

so it would not actually be rotation, it would just be the drawing of it

but like

rotation stuff, acceleration, decceleration, etc

[sleek hollow]

so everything from a paintevent?

[mighty frigate]

if my boss ask me to create something like this I would actively try to avoid it lol

[sleek hollow]

oh yeah 100%

I'd maybe hack something together with QDial, haha

[mighty frigate]

animation might be a good idea too it needs to be investiguate

the main problem I see is like, when spinning you want to know where you ended up

[sleek hollow]

I've only ever used minor property animations like colour or position

[mighty frigate]

by drawing all yourself, you know that without extra work

[sleek hollow]

I think as long as you know each segment size, and you know how much it rotated, you should be able to work out where it landed

[mighty frigate]

ok

found the best way

thanks to you

[sleek hollow]

oh yeah?

[mighty frigate]

you can generate a pie, or use an already existing pie from assets

and rotation an image in paintevent is painless

still have to handle acceleration and deceleration

[sleek hollow]

yeah, I thought using a pixmap and rotating it was the best way

[mighty frigate]

generating the pixmap itself if you want something dynamic might be annoying but maybe QtChart already have something that can do that

still, wouldn't want to do it lol, i'm too lazy

[sleek hollow]

yeah I think you're right that the chart is the best way to go about keeping it dynamic

[carmine pulsar]

so python is not the best

[mighty frigate]

Qt is a C++ framework with a binding in Python

[sleek hollow]

also how did I just learn that QLabel inherits QFrame....?

so much time wasted putting a label into a separate frame to style it

[mighty frigate]

doesn't matter the language for your task, only the UI framework you'll use matters

ahah

[carmine pulsar]

oh i see

i’ll find a good framework

[mighty frigate]

the quicker would probably be to look into html/js/css

because there's probably something ready out of the box written by someone else

[sleek hollow]

pygame might have something

[mighty frigate]

but it probably means all your UI would need to be in the web stack

https://doc.qt.io/qt-6/qml-qtquick-rotation.html#details
^ might work too

anyway

[sleek hollow]

Do you generally use qproperty animations at all?

To make things a bit more fluid feeling?

[carmine pulsar]

i’m not in web developing

…

idk where to start if i need to code it in css

[mighty frigate]

honnestly I don't really have the opportunity

I just started QML, as in I've been working with it for the last 3 months

and usually I work on industrial apps that's doesn't need a lot of polish

[sleek hollow]

Ahh fair enough

I haven't done a lot with it either, but recently started using animated background colour properties to indicate certain widgets

if they're missing information, or I want to draw attention

[mighty frigate]

I'm still not sure if I enjoy QML or not

[sleek hollow]

Haha what are the pitfalls?

[mighty frigate]

I feel like it solves some problems while creating others

I'm not sure, I'll get back to you aabout that in a few months

it's difficult to know if the difficulty I have is because I'm a noob with it or because it's a real flaw

I need more experience with it

[dull slate]

Hi

[carmine pulsar]

is it possible to create a spinning wheel (like the wheel of names) with customtkinter?

[azure talon]

The only thing I can think of is to create a animation or gif of a spinning wheel that takes a set time, do a random num between 100-200 and run the animation that % of time and figure out where it should land at.

[tribal path]

Can be done in any framework that lets you draw a canvas (I've made one in kivy) - but as noted you'd need to math it out

[zenith wyvern]

Yeah I know but do you think learning by documentation is great?

[sleek hollow]

do some tutorials to understand overall how it works, and then you can dig deeper into the documentation to learn new widgets

Once you get the process of creating a widget, adding it to a layout, and then manipulating that widget with method calls/signals/slots, you can apply that same idea to any widget

hello guys i really need your help since any fix on the internet i found is outdated. So i made this simple app and i'd like to make it possible for other people to download it and run it from their computers. I've made it an .exe file with pyinstaller but any time i bring it to desktop windows antivirus activates, deletes the file and proudly announces it to me. There must be another way to do this and if you know it please help me, also i am not sure which chat i should have posted this in so sorry. Thanks

@digital rose

[digital rose]

I'll give it a chance based on your word

Most tkinter interfaces I've seen look like windows 95 tbh but maybe I'm wrong

there is modern option

turns out you can download themes or something

styles

but it is very possible to build nice looking interfaces with tkinter

[swift storm]

question regarding an application that i am making

if i have a app booter and i want to add a software updater to this, how hard is this to achieve? If i have a version api and download server (which im developing rn), can i just overwrite certain .py files and thats it?

its just about the general concept of an updater

the question is more about the part of overwriting files rather than the download client + server, ive already researched that

[misty canopy]

that's a good question; I'd like to hear a good answer to it too :p
my first thought is "just overwriting python files is a bad idea; what if you need to remove some old files, too?". perhaps replace the directory with the new version, instead.

[swift storm]

mmm, i like both approaches

though replacing the whole directory may involve a way higher download size

but yea, what if you need to add completely new folders? What if you need to remove assets etc

what if you need to move files & data to another folder

im sure it wouldnt be too hard to create. I am mostly wondering what the best practices are

If something like this (open sourced) doesnt exist for python applications yet ill consider open sourcing my own system that ill create for it

[misty canopy]

looking at how one of the tools I know autoupdates does it, it seems the answer is innosetup - all of its releases are packaged with it, and when needed it downloads the latest release's installer from github and launches it.

that's a bad idea too - now your project breaks if you ever move it or upload it to github or whatever.

[inland wedge]

ok you can do it relative to the current file using __file__, or better for restructuring is to have some function that gets the projects path in some file at a constant location, and then paths are found relative to that

pathlib is good too

eg some file at constant location:

def getProjectPath():
  return pathlib.Path( __file__).parent

or even setting some global as it will likely remain constant during execution
then elsewhere:

icon= PhotoImage(
  file= getProjectPath()/ "images/omg.png",
)

pathlib is object oriented path handling and works with any function that accepts a pathlike, if not it can be cast to a string

Anything like Blazor in Python? Or anything that would allow you to build apps in a html-esque language? Idk

Been looking into pywebview but that requires Javascript I believe

[inland wedge]

perhaps the web assembly stuff could be of use ik there is some crossover with python

i think with web assembly one is still pushing content to the html backend layout thingy

ig gl area stuff exists

https://pyodide.org/en/stable/ this is cpython compiled to a wasm target, not some physical architechture like x86
so it can be run in the wasm browser ( virtual machine i believe) like that implemented in firefox

i mean there is stuff like relm too which is said to be declarative, relm specifically is rust tho
also the immediate mode stuff where the ui is completely generated each time step instead of incrementally but these are slower than incremental, especially with python probs

also both gtk and qt have markup languages

( builder xml or blueprint) or ( qml) respectively

but then you miss out on the dynamic construction of ui that a general programing lang gives you

[digital rose]

Good point, ah well. Guess I'll just keep learning Qt

[inland wedge]

well you could use qml

best of both worlds

[digital rose]

I'd rather just use python itself. Seems expressive enough

haven't tried personally

Personally driving towards the field of using templ + applying htmx. looks like really strong backend friendly combo.
templ gives me nice html/css templating with type safety and programming language usage.
htmx replaces me need to use javascript, it is rather rich in what it offers. Give a check for its overview here

what is the best gui module for python

[sleek hollow]

depends on your needs really

[rancid hamlet]

ok

[sleek hollow]

What are you trying to do with gui?

[rancid hamlet]

Like calculator modern one and snake game after it

[sleek hollow]

How new are you to python?

[rancid hamlet]

Like started 2 minutes ago

[sleek hollow]

Oh

[rancid hamlet]

I mean 2 months ago 🙂

[sleek hollow]

Ahh, haha

I'd recommend tkinter as a starting point. It's not the best gui, but it's fairly beginner friendly

[full willow]

Hello Everyone, I am a fairly new developer and I am looking for some guidance into picking a proper library / framework to use to build the app User interface

I am looking to build a modern user interface for a simple app for a medical xray device. This app reads the height and distance of the xray machine from the patient, using U-art protocol from sensors and displays it on the screen. It also sends motor signals to move the machine up and down, left and right using GPIO.
This app runs on a raspberry pi 4B

I am having a hard time determining which library to use to build the user interface. This user interface is simple but it does have a background image with Distance and height shown as text in a transparent card.

It also has a settings drop down for a configuration and calibration options which the user can interact with and set

What do you guys recommend? Any help would be greatly appreciated!

[meager valley]

whats the goal of having a venv honestly?

i thought by creating venv i could run the code in any pc i wanted.

[inland wedge]

since ur on linux, id recommend gtk, i wouldnt recommend it: if you need to use vulkan to draw ,if you need to embed x windows within the ui, if u need easy windows or macos support

I'm using babel to translate my interface to various languages. I was wondering if I should make a english.po file since all strings are in English so there's no need to create that file because it'll fallback to the english str in the app code

in kivy i want to make it so that i can scroll pass the left hand side offsets

but it gets cut off near bottom

im probaly gonna have to implement it myself arent i

is there anyway i can detect if a widget is off screen or nah

[tribal path]

Would be with a Scroll or Recycle View

[wicked helm]

im gonna put this off for now, right now im just trying to get the buttons instead of squishing together just get cut off if theres not enough space

    def hex_view(self,filename: str | Path) -> FloatLayout:
        a = Path(filename).stat().st_size
        
        root = FloatLayout()

            top -= OFFSET_LEFT_HEIGHT
        root.add_widget(left_hand_side_offsets)
        return root

look its squished

i just want it to but cut off into a void or something

[wicked helm]

i think ill have to implment this myself

[tribal path]

There is Stencil to cut out, and can oversize the Layout.
If you have a runnable example - can see what the minimal changes would be with what you have

[wicked helm]

class HexView(FloatLayout):
    def __init__(self,filename: str | Path,**kwargs):
        self.filename = filename
        super().__init__(**kwargs)
        
    def on_size(self,*_):
        a = Path(self.filename).stat().st_size
        leading_zeros = len(str(a))
        try:
            self.remove_widget(self.left_hand_side_offsets)
        except AttributeError:
            pass
        self.left_hand_side_offsets = BoxLayout(orientation='vertical')
        
        max_amnt = int((self.size[1] // 58.18181818181818)*16)

        for i in range(0,max_amnt+1,16):
            if i == 0:
                self.left_hand_side_offsets.add_widget(Button(text='Offset (h)',color=TOP_OFFSET,size_hint_x=.3))
                continue
            self.left_hand_side_offsets.add_widget(Button(text=f'{i-16:X}'.rjust(leading_zeros,'0'),color=TOP_OFFSET,size_hint_x=.3))
            
        self.add_widget(self.left_hand_side_offsets)
        print(self.size)

how would i make the offsets left fixed size

i want it to stay the same size when i make it wider but

it becomes wider

[tired rover]

does anyone know how to make widget genratation in kivy faster? cause i need to make around 250 widgets at once but its too slow

[wicked helm]

only make widgets when absolutely nesxary and change values on widgets instead

dont make it soo often basically

[somber hemlock]

250 ain't anything heavy

There must be something else going on

[mighty frigate]

using qml, how to make an item invisible but keeps its size and placement ?

[mighty frigate]

I've managed to do it by putting said item into another item with a size. That way, the layout can still figure out the placement wheiter or not its content is visible or not.

[flint marlin]

what do you call on this thing in notepad font window where
if you fill up the entry, it auto searches in the option list down below
and if you click something in the option, it fills up the entry

[sleek hollow]

Two separate events

[inland wedge]

Yh maybe with some lock to stop the click fill refiltering the results

Depending on how the toolkit works

[deft belfry]

does anyone know how can i register key presses using tkinter?

[sleek hollow]

you can use the .bind() method

[deft belfry]

ok ill try

[royal cape]

some resources on binding to events like keyboard presses:
tutorial (scroll down to "Binding to Events"): https://tkdocs.com/tutorial/concepts.html#events
Tk's introduction: https://tcl.tk/man/tcl8.6/TkCmd/bind.htm#M4
a list of keys you can bind to, such as <BackSpace>: https://tcl.tk/man/tcl8.6/TkCmd/keysyms.htm

[royal cape]

also its kind of mentioned in the resources, but in case you're not clear about it, tkinter will only send keyboard events to widgets that have "keyboard focus" so you'll need to be careful with what you call .bind() on:
https://tcl.tk/man/tcl8.6/TkCmd/focus.htm

At any given time, one window on each display is designated as the focus window; any key press or key release events for the display are sent to that window.
https://tkdocs.com/tutorial/concepts.html#events
You can also set up an event binding on a toplevel window. When a matching event occurs anywhere in that window, the binding will be triggered.
from what i can tell, some widgets like Text and Button automatically receive focus once you click on them, but other widgets like Label can't be focused on unless you manually trigger focus with the .focus_set() method

here's a demo if you want to play around with it: https://paste.pythondiscord.com/BUCA

Hi i am creating Build of my project
problem ===> size of the build is too much........

query === > i am using pyinstaller library to build , I am using only camera functionality of openCv and the size of the build is 56 MB
is there any practice to reduce down this size or can we extract the particular functionality of the opencv and use only this small functionality in our code so that the space it covers get reduced

Script===>pyinstaller --onefile aiii.py

Code
`import cv2
import numpy as np

class ai:

cap = cv2.VideoCapture(0)

i dont get this, as the web could mean anything which sends data between machines.
and any work making for example wasm code system agnostic, could be work on making some system agnostic system call abstraction no?

id say that pythons small use in graphics is due to it being a bottleneck in the cpu part of graphics rendering processes

in that case, python is a really good example of a operating system and hardware agnostic system

i guess software distribution is handled by sending ( compiled wasm binaries?) in wasms case on the web, or just javascript

there are also some excellent software managers out there though, such as gnu guix which allows you to inspect the source code of all software on your system, down to the handwritten binaries which bootstrap the process

in kivy what do i do so that i can display special unicode characters like \u263A
it just displays as that missing box with a X in it

[stray compass]

Is it available in the font you're using?

If that character isn't available in the current font, it'll default to the box with an X in it.
