Never no

#

all this like init stuff is really confusing to me

sharp plover
# 
import tkinter as tk

class App(tk.Tk):
    def __init__(self):
        super().__init__()
        ...

app = App()

app.mainloop()```I may or may not have stuffed that up, I'm on my phone. Writing things this way vs what I see a lot of with tkinter examples I feel is probably a better pattern.
#

It looks confusing at first.

versed dew
sharp plover
#

Class is to blueprint as class instance is to a thing created from that template.

versed dew
#

im sorry, huh? ๐Ÿ˜…

sharp plover
#

Like a button widget blueprint then the actual buttons themselves that behave in the way you designed the blueprint.

versed dew
#

that puts down the toughness-o-meter a little bit

sharp plover
#

So tkinter.Button is the blueprint, then you instantiate, create instances of, that class. Then you tkinter pack them to make them actually show up.

versed dew
#

so tkinter.button is basically your idea of creating let's say a mechanical clock, then creating instances is gathering the parts for that clock, and packing is to put that clock together and make it function, if im right?

sharp plover
#

Or you can write your own subclass of it. A copy of the that you then overlay/overwrite behaviours over the copy.

sharp plover
versed dew
sharp plover
#

Python is an object oriented language. Every object is of a class, a type.

versed dew
#

ohh

#

so like functions, operators stuff like that

sharp plover
#

Everything in Python that isn't syntax is an object or a reference to an object.

versed dew
#

with me i just write it down and debug it, then call it a program lol

#

i never actually think of what it means

sharp plover
versed dew
#

would a function be "if"?

sharp plover
#

Keyword. Syntax.

versed dew
#

yup

#

syntax makes things representable

sharp plover
#

Some objects are both keyword and object, which annoys me, but there you go.

#

Things like True, False and None.

versed dew
#

those would be Boolean values

sharp plover
#

Classes are how Python thinks, so it's really good to understand their workings, because it just opens up a lot of doors into how tkinter or any other code operates.

versed dew
#

right

#

python basically thinks in virtual

#

well ofc it does it is virtual

#

but things that are not there to it?

sharp plover
#

Pardon?

versed dew
#

i was thinking you were going to say that

#

so classes are things that are not there? it's confusing

sharp plover
#

Classes are objects.

versed dew
#

oh

#

so the opposite of what i was thinking

sharp plover
#

They have to exist within your code for class instances to be created from them.

#

But I did say that all objects are of a class, didn't I?

versed dew
#

yes, it's just really confusing because im figuring all of this out now

sharp plover
#

Class' type, their class, is type.

#

type is also a class, an object.

#

It's type is type.

#

Just to make it even more confusing.

versed dew
#

mind reader lol

sharp plover
#

So whenever you have a widget template class in tkinter that you want to modify the base behaviour of, subclassing, taking the base class and augmenting a copy, is a pattern I've found very handy, especially with the root tkinter.Tk widget...or maybe I'm thinking tkinter.Frame.

#

I haven't had breakfast, yet.

versed dew
#

oh it's morning for you?

sharp plover
#

So I'll go do that now. We may or may not cross paths again. I'll see if I can get my tkinter straight.

Does anyone know how to tell what is the dimensions of a text by just the font size (need this for pygame so it is kinda related)?

tribal path
#

depends on font itself as well, would look for a render size (or use pil I suppose)

#

Using argparse I want to denote object which commands relate to by for instance:
vehicle move <some_specific move params>
My current approach:

vehicle_parser = subparsers.add_parser('vehicle')
vehicle_subparser = vehicle_parser.add_subparsers()
cmd_vehicle_move = vehicle_subparser.add_parser('move')
cmd_vehicle_move.add_argument("frame", nargs=1, type=str)
cmd_vehicle_move.set_defaults(func=cmd_vehicle_move_impl)

This seemingly works! inputting vehicle move calls the -h. However, argparse also allows for input like vehicle. Is there any way of being able to say vehicle is invalid on its own by default?

sudden coral
#

Actually, since this is a subparser, maybe what you're after is add_subparsers(required=True)

Is there a way to create something like a menu in Qt Designer/PyQt? (What I mean is you have a main menu screen that has different options and when you click on one of the button widgets it will take you to a new page inside that button? Then have a back button to go back to the main menu. If I exampled it bad let me know and I'll try to explain further.)

@hearty boneI'm not sure I perfectly understood what you wanted but it sounds like a few QPushButton with a few QWidget

you can take a look at QTabWidget also, you can do nice things with it (with a bit of styling)

no clue what you mean by that

how to convert pyqt5 wondow user interface to a .ui file

mighty frigate
#

@high oceanfrom code to .ui file ? can't afaik

slim cairn
#

i am making custom colorchooser which will provide user realtime update of change of colors in UI and user will have some options of colorwheels to choose from.
the feature i want to add is that when there is no argument provided it creates a new window showing colorchooser
for example:

widget = ColorChooser(master=None, some_paramteters_to_be_Added_in_future)

when user provides master for the widget (ie user want to place colorpicker into his window) he provides master argument
for example:

abc = tk.WIDGET(...) # WIDGET can be Frame, LabelFrame, Canvas, Label object
abc.pack(...)

wid = ColorChooser(master=abc, some_paramteters_to_be_Added_in_future)
wid.pack(...)

this will let user to choose color from its own window
the problem is that i cant decide that how i goona implement both feature in a single class

I'm kind of stuck in deciding how to design a GUI for my applications
Previously I was using the gooey module to generate a basic GUI based on the command line arguments that the program accepts, but it's very rigid and can't really have elements change dynamically
I worked with PyQT / PySide before, but development for it is quite a pain

Then I came across the PySimpleGUI library, which attempts to standardize the usage of the major existing GUI libraries (Tkinter, PyQT, WxPython, and a basic web GUI through Remi)
As nice as it is, and with it simplifying a lot of the code of the other major libraries, it's still a pain to design something since you actively have to open/close the app to see your changes. There's no real way to draw a mockup like you could with Qt Designer, so it's all just trial and error

So now I'm pondering if I should bother sticking with PySimpleGUI, or just look into developing a full-stack localhost web server with some JS framework like React for the frontend
Even though that would also be complicated, it'd be easier to transfer boilerplate code between any of my applications, instead of having to redesign the GUI for each and every app

Does anyone have any insight or suggestions for this? I'm trying to maximize my time and make the code as reusable as possible, while still having a dynamic and reactive frontend

slim cairn
#

the one thing i agree that for changes to be shown we have to open and close the application. In my current project i also have same issue as i want that a user can have changes shown and applied in realtime without exiting the application. since this will be the end part of stage 1, havent thought of any solution. the solution comes to my mind is to have a function or might be seperate class but still unclear about the complexity i might face.

sacred dirge
#

There also seems to be the cli2gui library which is basically gooey in terms of creating GUI elements based on command line arguments, but is built ontop of PySimpleGUI
Which unfortunately brings me back around to my initial issue with gooey where you can't update the GUI dynamically

mighty frigate
#

@sacred dirgeQt is definitively the more evolved solution out there.

I'm looking for a way to have an image resize accordingly with the size of the window, while maintaining the image's aspect ratio.
If the image is larger than the label, it will get cropped, or if scaledContents is used, it will get stretched (both of which are not what I'm looking for)
What I want is to have the image fit the frame it's in while keeping its aspect ratio.

Does anyone have a way of doing that?

NOTE: I'm using PyQt5 for this

Ohh i was making custom color picker for my chess so that user can see the color changing realtime while tweaking the looks of gui, since the color wheel dont shows all the colors i thought to fill that gap by slowing moise cursor and to interpolate between the color,
If u use blender3d then u might have know that while dragging if u press shift jey the cursor slows down giving u smooth and precise cursor movement

queen spade
#

@sinful pendantsounds like it could work as a design tool

#

some sort of animation of the color (when the user wants to change the color) that goes back and forth between the old color and the color the user is considering

#

@slim cairn maybe the idea of the color animation would be somethign you could use too

slim cairn
#

instant swapping between colors might not be good idea when user wants to see the color he selected on board, currently no plan for this type of thing

How to create your own Question-Answering system from a google sheet easily with python and design an interface?

queen spade

#

@mint mangoso you probably need to make sure you know python pretty well, and for the interface part you need to pick one possible interface framework and work with it, learn it like you would a language (like python)... because it is... and then, take some design courses

#

@mint mangoafter all that work you should be able to design an interface, and build something that responds to the user, using that interface. probably take you about 3 or 4 months, with the python part probably being the easiest

Hi everyone,

We are planning on developing an app which will have a facial recognition aspect and some machine learning aspects. This is a senior design project for our class so none of us are exactly experts. But we are trying!

I have done many ML projects but never an app using python. Our professor suggested using Flutter as its cross platform. But from what I am reading it may not be the best option for python APIs.

Could you let me know what your thoughts are for mobile development what should we use if we are decided on python APIs already?

Hello, I'm working with PyQt5 and I've been googling for an hour but cannot figure this out. I have a QTreeWidget, and I would like to add a checkbox to the toplevelitem, but in column 2, not column 0. I've copied and pasted code from stack overflow so many times that I don't remember which example I used to get a checkbox into column 0 of the top level item, but I was able to at least get that working before (I don't have that code anymore, and don't remember to do that again), but regardless I'm trying to place a checkbox into column 2.

I have this so far, but it's not working:

item_0 = QTreeWidgetItem(self.ui.tree_widget_path_config)
item_0.setFlags(item_0.flags() | Qt.ItemIsTristate | Qt.ItemIsUserCheckable)
item_0.setCheckState(0, Qt.Unchecked)

Can anyone point me to an example of how to do what I'm trying to do?

Hello: Trying to use Win32com with Python and using my own app in Python. I want raise events from a separate SAPI module running independently and have my app fire on those events. Or have the SAPI code generate the events and my app fire on them.

Hi,
I need to create big menu using PyQt5 (PyQt5.QtWidgets.QMenuBar) and currently I'm creating it using dict and for loop but to achieve what I need I would have to create almost new library (which will check if item should be checked or not, adding icon for item, disabling/enabling position etc).
Anyone of you know simple solution to create big menu using dictionary or some library which will help?
I don't want to create hundreds of lines of code just to create a menu and my solution is not complete.

anyone ever used a recv socket inside Tkinter's event loop

#

basically I have 3 buttons in my GUI that send requests to a server

#

and then I need to keep my recv function online while recv

#

However I'm using a while True loop in my socket

#

and I don't want the GUI to freeze

#

while receiving data

#

@wind spire with tkinter you need to make sure if you want to run a blocking code (like a while loop) you want to put it on another thread, using threading to start another one or multiprocessing

wind spire
#

Okay

#

So I put it on another thread and it's still locking up

#

i'll post the code in one sec

#

nevermind

#

I got it working lol

Thanks

@past cradlecan you provide a small sample of your input dict, as well as what the resulting QMenuBar would be pls ?

I'm new in PyQt5 (just started) and this is more test/learning project so I'll need to refactor this code.

    self.menu: List[Dict[str, Dict[str, Any]]] = list(dict())
    self.menu = [
        {'File':            {'submenu': 'MenuBar', 'action': lambda: self.info(), 'menu': True, }},

        {'Open':            {'submenu': 'File',    'action': lambda: self.info(), 'shortcut': 'Ctrl+O'}},

    self.menu_bar.clear()

    for item in menu:
        for key, value in item.items():
            if value.get('menu', False):
                self.create_menu_bar_submenu(value['submenu'], key)
            elif key == '-':
                if not self.menu_bar_submenus.get(value['submenu'], False):
                    self.create_menu_bar_submenu(self.menu_bar, value['submenu'])
                self.menu_bar_submenus[value['submenu']].addSeparator()

                self.menu_bar_items[key].setText(self.translator.translate(self.preferred_language, key))
                self.menu_bar_items[key].setObjectName(f"action_{key.lower().replace(' ', '_')}")
                self.menu_bar_items[key].triggered.connect(value['action'])

                self.menu_bar_submenus[value['submenu']].addAction(self.menu_bar_items[key])
#

I'm looking for ready-to-use solution.
In case of creating it myself I prefer to create new component class which will create menu based on dictionary. So this code will be refactored ๐Ÿ™‚
For now it's more like Proof of Concept code because I'm still learning PyQt5 ๐Ÿ™‚

i would recommend pysimplegui, i've just started with python and i've found it pretty easy to pick up

#

Theres also tkinter. Maybe a little mkre complex but still quite easy

#

Imo you will need some basic knowledge about oop and async programming for tk

You know how

     widgets.destroy()

will remove labels inside the specify frame. However, it doesn't remove entry boxes. How do you destroy an entry box and not just clear the contents of an entry box?

#

While just using tkinter

unique mural
#

I'm using tkinter and trying to set the grid of my entry but no matter how I set the row and column values, it stays the same.

#

It's currently set to row 5 and column 5 but stuck here in the corner.

unknown.png
signal hound
#

do the other rows/columns need some sort of content to pad them out?

digital rose
#

What you should do is putting something in that 1-4.

#

like Labels, tk.Label(root).grid(row=n, column=n) where n is {1, 2, 3, 4}.

unique mural
#

Okay I'll try that

digital rose
#

I didn't use grid before but if the grid system count and consider 0 that n should have 0.

After putting in another widget (label), it worked perfectly.

# hushed magnet Should I got with dearpygui or tkinter for something user-friendly ?

if you are trying to make a very highly functional, responsive app, i would recommend not tkinter. If you are doing something fairly simple like, a databasing app or using a specific protocol or something, just for a user to click buttons and enter things, use tkinter. simple stuff is simple, but don't try to make it look nice or go too crazy with much

Morning, is anyone here familiar with Customtkinter?

devout shale
#

Does anyone use IronPython? I'm trying to use this in VSC (Visual Studio Community 20XX)

#

I installed it properly, but this crap won't show anywhere in the projects tab as an IronPython WPF Project

#

I tried on 2017, 2019, 2022... lol

#

I give up, I have no idea what is going wrong and I've been at this for a few days now.

#

I just need to develop a functional fucking gui and the python user interface libraries, SUCK.ASS. And the only thing that can have any sense in all of this mess is IronPython.

eager beacon
devout shale
#

@eager beacon the learning curve for a python gui library is steep as hell

#

whereas I already know the wpf libraries

#

and I could not find any guibuilder for python that has the same power as the .net one

#

there's nothing as easy to use as the .NET, you create the object and the properties of the object are easy to access, modify and so on

eager beacon
eager beacon
devout shale
#

i don't even understand how the python gui libraries handle method handlers

#

like in C# you could handle the .click event of an element with a delegate

#

in python it's chaos

#

how can I even humanely design a gui with the hopes that someone can read this?

eager beacon
#

well, TKinter is a mess, so don't make a judgement based on that alone.

eager beacon
devout shale
#

don't I need to buy QT to use that?

eager beacon
#

Not necessarily.

#

The Qt licensing is actually pretty decent

#

There is Qt Designer, which is pretty much the same thing as Creator, at least as far as the design process goes.

devout shale
#

Ah I see

#

Qt Designer uses Windows Forms basically

#

Kind of a disadvantage

#

Meh, I'll look into it

#

Not many strong tools with this language

eager beacon
#

The designer app exports an XML file that you can convert to Python with pyuic.

eager beacon
#

If you want to be able to develop a cross platform app is by far the best choice

devout shale
#

I guess my best option is to create my GUI in C# and create logic for interacting with the interpreter for running python code, by creating procedural python code using C# using my libraries

#

Feels so homebrew tho

#

But I guess the user doesn't have to see the interpreter open at all in a terminal, since I can hide it, so ยฏ_(ใƒ„)_/ยฏ

#

I'm dead set on using python for the backend and C# for the frontend .NET

#

Selenium and PyWinAuto are too strong of tools in python (even though Selenium is in C# as well)

#

Selenium feels a whole lot different in Python

#

lol

eager beacon
devout shale
#

Maleability

#

And knowledge of the already existing interface

eager beacon
devout shale
#

PyWinAuto

#

mainly

#

I could probably replicate my python Selenium code in C# as well, but Python saves me a lot of typing the code

eager beacon
devout shale
#

couldn't find one ๐Ÿ˜ฆ

eager beacon
#

Is there a reason you don't want to use ahk?

#

Isn't that the goto automation tool for windows

signal nebula
#

so that you can mix it with other languages like C#

devout shale
#

i only know of ironpython

signal nebula
#

oh, maybe, i though python was included among the languages supported within .net
and the one of selling points of .net was that you could mix languages within a project quite freely
but excuse my ignorance, i'm a full time linux user since many years

devout shale
#

but it isn't a complete implementation that harmonizes with .NET

#

it's better to just do it in C# and just pass to the interpreter the commands, python.net does the same

#

for example you can't make a python WPF project, you have to do everything manually from code behind, including designing the interface, no XAML friendliness

#

so it's still better to use C# for the frontend and handlers and use python to run the code

#

you'll understand why this implementation is needed

#

if I explain my project

#

I want to make an RPA software, this RPA software needs to package executables that run automations

#

Doing this with python is very easy with pyinstaller

#

So I can just use the C# framework as the master, and python as the slave

#

It's easy to generate code procedurally in python with the libraries I wrote in python

#

So it links together nicely

#

And doing this, I don't even have to expose my python libraries to users to modify or steal

eager beacon
devout shale
#

I can just hardcode it in the application.

#

It is time sensitive unfortunately

#

And besides python syntax, basic stuff, I don't know much of python

#

I don't think this solution is nasty though

#

I can definitely work like this

#

With no weird knowledge walls to go along the way

eager beacon
devout shale
#

Yeah, it isn't too complicated

#

It's basically UiPath

#

You drag and drop shit in a canvas

#

Then behind it, code is written procedurally

#

Then when you compile to run it, the python interpreter will take it

#

Mostly selenium and pywinauto

Hey there, I'm trying to create a simple 5x5 grid UI with PySimpleGUI which consists of buttons which when click would set the text inside of the box to some text/number but I'm not really sure how to achieve this.
This is what I'm aiming for:

unknown.png
signal hound
#

then you could probably just update the text on click with something like:

if event == 'btn_name': 
    window[btn_name'].Update("some text / number")
#

is the text/number linked to the button that's clicked or random ?

green olive
#

the way i want it to work is the user will be presented by a random generated number and theyโ€™ll have to select an unoccupied grid tile to place the number in

signal hound
#

then i guess you'd store the random number in a variable and then update the text in the same way

#

just using the variable in place of "some text/number"

signal hound
#

something like this perhaps:

import PySimpleGUI as sg
from random import randrange

row1 = [sg.Button("N", k='btn_1.1'), sg.Button("N", k='btn_1.2'), sg.Button("N", k='btn_1.3'), sg.Button("N", k='btn_1.4'), sg.Button("N", k='btn_1.5')]
row2 = [sg.Button("N", k='btn_2.1'), sg.Button("N", k='btn_2.2'), sg.Button("N", k='btn_2.3'), sg.Button("N", k='btn_2.4'), sg.Button("N", k='btn_2.5')]
row3 = [sg.Button("N", k='btn_3.1'), sg.Button("N", k='btn_3.2'), sg.Button("N", k='btn_3.3'), sg.Button("N", k='btn_3.4'), sg.Button("N", k='btn_3.5')]
row4 = [sg.Button("N", k='btn_4.1'), sg.Button("N", k='btn_4.2'), sg.Button("N", k='btn_4.3'), sg.Button("N", k='btn_4.4'), sg.Button("N", k='btn_4.5')]
row5 = [sg.Button("N", k='btn_5.1'), sg.Button("N", k='btn_5.2'), sg.Button("N", k='btn_5.3'), sg.Button("N", k='btn_5.4'), sg.Button("N", k='btn_5.5')]
row6 = [sg.Text(" ")]
row7 = [sg.Push(), sg.Text("Random number:"), sg.Input("x", key='rand_num', size=(2,1), justification='center'), sg.Push()]
row8 = [sg.Push(), sg.Button("Generate", k='gen'), sg.Push()]

layout = [[row1], [row2], [row3], [row4], [row5], [row6], [row7], [row8]]

window = sg.Window("5x5", layout,  no_titlebar = True, grab_anywhere = True, finalize=True)

window['rand_num'].update(randrange(10))

while True:             # Event Loop
    event, values = window.read()
    print(event, values)

    if event == sg.WIN_CLOSED or event == 'btn_quit':
        break

    if event == 'gen':
        window['rand_num'].update(randrange(10))

    if event.startswith('btn_'):
        btn_val = values['rand_num']
        window[event].update(btn_val)
        window['rand_num'].update(randrange(10))

#

Okay so lately I've been trying to make UI's to my scripts, makes them more user friendly yada yada
I've come across an issue in one of my scripts

For context
The script consists of reading a directory of files
Hashing a bunch of game archives and hash them
Update the game
Check archive hashes for changes and extract only archives of the game that have been changed
Extract the files using the game's executable which provides a tool that turns archives into the individual files
Hash files in directory before and after extracted to make a directory just for changes and removals
etc etc etc, optimize the extraction process that usually just takes place in the whole game but it's highly inneficient and slow to do so, so I use hashes to skip over unchanged archives

The issue I've ran to is that
While using PyQT5
I created a QRunnable object which runs the extraction of each archive that I user selected and I checked hashes for
this QRunnable is then thrown into a QThreadPool
HOWEVER
some of these (namely the ones which extractions are biggest) take an immense amount of time or even don't complete at all
at first I thought it was that the process of extracting was being bottlenecked by the parallel ones (even if threading is supposed to take care of that?)
I ran that extraction as a single one and still got stuck and didn't complete, the process of extracting that folder is usually up to a minute but I went about 2 hours of waiting to see if it was just slow and it just didn't complete

Here's the code, note that I am new to PyQt and threading as whole, please don't be mean but point out any mistakes I made
https://mystb.in/JuicePixDeposits.python

#

I'd also like to add that this script without the threading and what not, does run fine and super quick...this is not a new thing I am trying to do, as I mentioned I am converting my existing scripts to UI

I feel like my mistake is how I am handling the threading and subprocessing but I have spent hours trying to read online documentations and articles and I've just been unable to pin point the problem with my implementation

#

not all Runnables fail though

#

@mention if you got anything to add to my issue because imma keep trying to research it a bit

First, you should know python fundamental components.
Second, try searching "GUI python libraries" you can see a list of all GUI (Graphical User Interface) libraries that supports python, every one of them have its own futures, information, etc. pick up what you want, i advice you in PyQt.
Third, learning the GUI library you picked up.
Fourth, start creating your app.

I'm asking about your example, the one you've shown

If you want to change the signature of the callback, that's a different deal

#

And it's not related to tkinter

spring drift
#

it wouldn't really matter in this case but lambda will handle call backs better than just a bare function

timid dust
#

That's just wrong. Dropping a "it's always best to use lambads" with that example is misleading at best. If you're running into issues where you want to change the signature of the function, or pass a local variable, then yeah lambda could be the right tool. Lambdas won't magically make every function they touch better, such as in your example

Hello, what do you think about learning the whole python tkinter module?

slim cairn
#

things are limited and you get an old looking interface. if you are making app which needs to have an attractive interface then tkinter not the choice. there is so many widgets option but there is not much flexibility for change. It is decent to provide u a good looking interface.

#

tkinter is easy to learn

#

tkinter can be lil more beautiful if u use some extrnal tools for interface

somber hemlock
#

Compared to something like WPF or Avalonia its complete trash, use a design pattern for working with GUIs. Use OOP, Tkinter was made with nothing of that sort in mind

#

You can't test your UI or your code because those two are coupled in Tkinter.

this tkinter with grid system right ?

digital rose
hearty matrix
#

why isn't the frame taking up more space, despite using nsew?
how do i make it occupy the full area of the cell 1,0?

hearty matrix
#

i mean

#

it's more of a general doubt than an error

digital rose
hearty matrix
#

what does that do?

digital rose
#

i mean the grid

hearty matrix
#

ok hold on let me try it

digital rose
#

so you should put some width and height in frame = tk.Frame(main, width=200, height=200, bg = 'purple').

hearty matrix
#

so that means

#

there is a default width and height of a cell?

digital rose
#

It's not the ideal solution.

hearty matrix
#

because when i'm not using sticky at all, then the frame isn't even showing

#

but the next label is still occupying the same amount of space

digital rose
hearty matrix
#

but then why is the frame widget taking only that exact amount of space?

digital rose
hearty matrix
#

because the cell above has columnspan has 2

digital rose
hearty matrix
#

i see now

#

it's a default.

#

COOL

#

well thanks!

digital rose
#

Nope, i did nothing.

hearty matrix
#

also

#

one more thing

digital rose
#

Say

hearty matrix
#

nvm nvm

#

i figured it out

digital rose
#

Ok

hearty matrix
#

i think i might finally be able to place some stuff

digital rose
#

Nice.

hearty matrix
#

i want to confirm something

#

when i create a grid

#

and place something in the first cell, is a second cell automatically created?

digital rose
hearty matrix
#

(one sec)

#

why is that happening?

#

i've set the pink label's sticky to ew as well

#

and that space is getting filled up when i add another widget

digital rose
#

because the frame width and the original frame's cell.

#

?

hearty matrix
#

what?

digital rose
#

i mean the second cell is not created, when you see that the space filled up because the space in the original cell, try to type more text to the first frame's label and see if there is any space.

hearty matrix
#

ok hold on

#

but shouldn't that be filled anyways if i use sticky ew?

hearty matrix
hearty matrix
digital rose
#

I didn't deal with grid before

hearty matrix
#

oh alright

#

so somehow sticky is not working when I'm placing stuff inside frames

#

weird

#

thanks anyhow

digital rose
#

You are welcome.

I can't see something not good, every thing ok i guess

remote light
#

Ah perfect, first time working with class inheritance etc

digital rose
#

I don't know why you guys use grid a lot

remote light
#

Cause uh, grid is sort kinda 'visual' to me

#

with packing i'm not exactly getting what i'm doing

#

but am working first time with tkinter aswell

digital rose
remote light
#

but place is like, x/y coordinates?

digital rose
#

yes

remote light
#

but that doesn't make your app 'hybrid' if you wanna scale right?

digital rose
#

and relwidth, relheight, relx, rely.

remote light
#

and rel = relative?

#

relative to what? the canvas size?

digital rose
digital rose
remote light
#

mhm

digital rose
#

if window resize it will resize yk

remote light
#

yea exactly

#

nah, for now its doing what i want and need

#

its not gonne be a big app tho

#

but more cause my colleagues can't work with python terminal :p

#

so i'll try it this way first ahah

digital rose
#

as you wish, i see that place is more tidy.

remote light
#

Do u have a small example?

digital rose
#

since ETK uses only place

digital rose
remote light
#

mhm okay

#

Thanks for the mention, i'll dive in it later

#

First i have to make it work ASAP so they can work with it, and will rewrite tidy that way ๐Ÿ™‚

digital rose
#

As you wish.

remote light
#

so, place its gonna be i guess

hearty matrix
#

do the elements inside the frame decide the dimensions of the frame? (tkinter)

hearty matrix
#

the width of the green frame has been defined as 300, and the width of the label with text 'zero' is 40, why is it stretching out and not fitting into the frame?

I just asked how I can set the background color of a custom widget in PyQT in the #help-falafel channel. Could someone help me please?

heavy ingot
mighty frigate
#

@radiant dirgethe common way is to use stylesheet, something like myWidget->setStylesheet("QWidget { background-color: white; }");

#

for a custom widget, you can sometimes have problems with the stylesheet. The solution is to make the custom widget style-aware

# 
 void CustomWidget::paintEvent(QPaintEvent *)
 {
     QStyleOption opt;
     opt.init(this);
     QPainter p(this);
     style()->drawPrimitive(QStyle::PE_Widget, &opt, &p, this);
 }

this is cpp but it's pretty much the same

Do you have to learn the .kv language in order to make some more complex guis in kivy or does it just make it easier to write?

tawdry mulch

#

It is like using absolute position in CSS

hearty matrix
#

wait so

#

suppose i turned on propagate to false on a frame

#

but i want to center elements in it

#

how do i do so?

#

and do i make widgets fit inside it?

tawdry mulch
hearty matrix
#

i see

#

grid

tawdry mulch
hearty matrix
#

let me see

#

oh you want the layout

tawdry mulch
hearty matrix
#

sure hold on

#

this is it currently

#

I'll share only the code for the green frame

# 
#navigation tab
left_frame = tk.Frame(main, height = 650, width = 300, bg = 'green')
left_frame.grid_propagate(0)```
# 
#elements inside the green frame

zero_button = tk.Label(left_frame, text = 'zero', width = 40, height = 5, bg = 'red')
one_button = tk.Label(left_frame, text = 'one', width = 40, bg = 'pink')
two_button = tk.Label(left_frame, text = 'two', width = 40, bg = 'blue')
three_button = tk.Label(left_frame, text = 'three', width = 20, bg = 'purple')```
# 
#placing the widgets

zero_button.grid(row = 0, column = 0, columnspan = 2)
one_button.grid(row = 1, column = 0)
two_button.grid(row = 2, column = 0)
three_button.grid(row = 2, column = 1)
left_frame.grid(row = 1, column = 0, padx = 3)
#

that's about it

tawdry mulch
hearty matrix
#

how do i do that?

tawdry mulch
hearty matrix
#

but i want the frame to remain this size only

#

wait wait i thought of something

#

hold on

#

no :<

#

when i use the width parameter for something inside the frame, it's not working ;-;

#

i mean

#

it's scaling differently

digital rose
tawdry mulch
tawdry mulch
hearty matrix
tawdry mulch
# hearty matrix yep

It depends on your widgets. Widgets like buttons and entry widgets don't use width in pixels. It uses in a different unit

hearty matrix
#

ooh

#

OOH

tawdry mulch
#

I think it uses the width of the '0' of the font and does the calculation.

hearty matrix
#

and also about centering, then i can just use grid stuff right?

hearty matrix
#

that helps a LOT

tawdry mulch
hearty matrix
#

i will

#

do you know the conversion?

tawdry mulch
#

Conversion of?

hearty matrix
#

between the different units?

#

of width for labels and frames?

tawdry mulch
hearty matrix
#

oh

tawdry mulch
# hearty matrix i will

basically you can turn of propagate and then use weights. Let me see if I can build an example

hearty matrix
#

thanks :)

tawdry mulch
# hearty matrix thanks :) 
from tkinter import *

root = Tk()

frame = Frame(root, bg="red", width=500, height=500)
frame.grid_propagate(0)
frame.pack(padx=50, pady=50)

Button(frame, text="This is a button").grid(row=0, column=0)

# Weight is like a way to manage empty space. It says the column/row to grow id there is empty space
frame.columnconfigure(0, weight=1)
frame.rowconfigure(0, weight=1)

root.mainloop()

Once you remove <column/row>_configure it will show how it supposed to look originally

There is a dedicated tkinter server were you could get better help

kindred mist
#

anyone have experience with QPainter and Handdrawing? I have an Coordinate Problem. And after 3hours ive realy done ๐Ÿ˜ฆ

mighty frigate
#

@kindred mistplease elaborate

kindred mist
#

@mighty frigate i have a Code, if that helps,
but the main problem is:
i would paint on an canvas(pixmap) if i do this in the designer perfect on the upper left corner (0,0)
I can paint perfectly in it. But if move it to the place i need, i have to pain on the top left corner, to get in the painting canvas.

#

i think, its a coordinate problem from the mouse event or from the pixmap

mighty frigate
#

you probably need to map your coordinates from one widget to the other

#

there's a collection of functions that do that, depending on what you actually need

#

I can't run your code because of the designer thing, but from what I've read on your stackoverflow post, you probably need to map your corrdinate from the QMainWindow to your labelSign

#

@kindred mist

kindred mist
#

hmm

#

ok, then i have to look, how to map coordnates

mighty frigate
#

alternatively, you can subclass labelSign and override its mouseMoveEvent

#

you won't have to map your corrdinates then

kindred mist
#

how?

mighty frigate
#

look at the link I gave you, there's all the mapping functions in there

#

it's c++ but it doesn't matter, it works all the same

kindred mist
#

na, it doesnt because the syntax from c++ is weird ๐Ÿ˜„

mighty frigate
#

it doesn't matter.

#

the functions have the same names, the arguments are the same, the returns are the same

#

it's functionnally the exact same as the Qt python binding

kindred mist
#

the problem ist, where to map, not what to map. I know the problem with the coordniates.
But i didnt know where to map that things

mighty frigate
#

from what I've saw, your coordinates comes from the QMainWindow

#

but you've created the QPainter as a child of labelSign, so it will use the origin and the size of it

kindred mist
#

painter = QtGui.QPainter(self.main.labelSign.pixmap()) this?

mighty frigate
#

wait that a good quetsion

#

labelSign is a Qlabel right

kindred mist
#

yes

mighty frigate
#

have you actually managed to draw anything inside the QLabel that way ?

kindred mist
#

yes

mighty frigate
#

so it's somehow working

#

hm

kindred mist
#

thats working

mighty frigate
#

I wish I could run that code to be sure before talking

kindred mist
#

i can pack you all that stuff

mighty frigate
#

give me a sec

proven basinBOT
#

Hey @kindred mist!

It looks like you tried to attach file type(s) that we do not allow (.zip). We currently allow the following file types: .gif, .jpg, .jpeg, .mov, .mp4, .mpg, .png, .mp3, .wav, .ogg, .webm, .webp, .flac, .m4a, .csv, .json.

Feel free to ask in #community-meta if you think this is a mistake.

kindred mist
#

ive tried to move it in code, but same results, the painter uses the 0,0 start coordinate

mighty frigate
#

ok I got it to work

#

it's funny it's working tho, I guess I learned something today

#

anyway

#

what's not working again ?

kindred mist
#

I can draw on the left upper corner ( so it starts on the 0,0 coordinate)

#

if u move the label field to somewhere else

mighty frigate
#

ah yes

kindred mist
#

i can draw in it, when i move the mouse the upper left corner

mighty frigate
#

because coords aren't mapped

kindred mist
#

yes

#

my problem is, i dont know how to do that (and i dont understand the documentation well)

mighty frigate
#

let's be honnest you didn't really try :p

#

give me another sec

kindred mist
#

i think its somewhere here: painter = QtGui.QPainter(self.main.labelSign.pixmap())

mighty frigate
#

against all odds, that's actually correct

#

I don't understand why but it does work

#

one could have though that pixmap was const, or at the very least a copy

#

so drawing in it would either crash or do nothing

#

but it works

kindred mist
#

but not for me atm ^^

#

and i still dont know where to map from where D:

mighty frigate
#

it's just coordinates problem, the principle works

#

yeah yeah give me a sec

kindred mist
#

ya i know, thats what i know 1 hour ago ๐Ÿ˜„ but the warming burns my IQ away today so i dont get solution ^^

#

@mighty frigate .... i got it

mighty frigate
#

you do ?

kindred mist
#

my brain works after a cold shower ^^

# 
        painter = QtGui.QPainter(self.main.labelSign.pixmap())

#

I'm trying to convince Qt to go with global mapping and localizing it again but so far it doesn't cooperate

kindred mist
#

QPainter have to you an Viewport and an Window, so the Window in QPainter ist the active drawing canvas -.-

#

what an dramatic disaster -.- sorry

wth

how do you come up with those kind of fix

why does this even works

sry for the formating, it was too long

tbh honnest I think your fix is better

I would never though of that

global_p = self.central_widget.mapToGlobal(e.pos())
local_p = self.label.mapFromGlobal(global_p)
That is the mapping function right?

is there any online gui maker for python or any drag and drop one?

broken shard

so the only good gui drag and drop programm is Qt designer

but PyQt is more complex than tkinter I guess

digital rose

what should i do now? so far all i have done is learn a few basics for pyqt5 and made a calculator and a note program. What should i do next?

mighty frigate
#

@digital rosewhat's your goal ? learning more about Qt ?

digital rose
mighty frigate
#

@digital roseyou're using QtWidgets, correct ?

#

not QtQuick

digital rose
mighty frigate
#

imo there's key concepts that any devs using QtWidgets should know about : Signal/Slots, Events, and Model/View

#

signals/slots and events, you've probably seen already

#

so you might want to take a look to the model/view concept of Qt

#

for example, you can make a file explorer

digital rose
#

:ooo

#

:oooo

#

alr, ill check it out, thanks for the info

mighty frigate
#

as for the project, anything that fit in a table or a list will do

#

or a tree

rocky dragon
#

How are Qt palettes inherited/passed around? I have a widget I want to set the background on without affecting the background of its children (same type of widget), all of them have auto fill background set. But if I don't set the Window color role on palette of the child widgets to a different color, the change to the parent is also done on all of its children. For example with https://i.imgur.com/hY50bev.png (widgets are what you'd expect from the frames), coloring the outermost widget colors everything else if the palette is not changed, or if it is a palette with the same color set for Window as the default color

Imgur
digital rose
mighty frigate
#

@rocky dragonI wouldn't recommand playing with QPalette, you'll break all your stylesheets

#

what you can do is setting a name to your widget (https://doc.qt.io/qt-6/qobject.html#objectName-prop) and setting a stylesheet to your widgets by selecting them by those names :

label = QLabel()
label.setObjectName("LabelName")
label.setStyleSheet("QLabel#LabelName { background-color: blue; }")
#

Also, I don't know what you're trying to do here, but this looks like a tree to me. There's components built-in for trees in Qt : QTreeWidget and QTreeView (using Qt MVC)

final escarp
#

any tutor about building apps with Qt in Gnome?

mighty frigate
#

why in gnome specificaly ? Qt is multiplatform, you shouldn't need anything special to run a Qt app in gnome.

#

afaik anyway

rocky dragon
mighty frigate
#

@rocky dragonQt's model/view can be tricky at first, but most of the time it's the best way to go

#

what do you want to achieve exactly ?

#

if you don't want to customize the looks of your item in the tree, you don't need a delegate

#

you need a view and a model

#

namely, a QTreeView and a QAbstractItemModel subclass

#

if your tree will only contains simple data (like a tree of strings), a QTreeWidget and a collection of QTreeWidgetItem will do the job

do you need those borders ?

rocky dragon
#

I need some easy way for users to differentiate between what belongs to what widget

mighty frigate
#

would ill a tree do the trick for you regarding this ?

#

example :

rocky dragon
#

I suppose it would

#

do you want to be able to expand and collapse your labels ?

Hi

rocky dragon
#

Yes, I collapse a widget's children and then the whole widget including labels except one

mighty frigate
#

Will you use complex datas ?

#

Status, icons, search, filters,...

#

Or do you just need to display a string and or an icon ?

#

Also do you need to edit the datas

rocky dragon
#

I believe it should just be a couple of separate strings and a button in there for every (non collapsed) widget

I just want to ask what are the necessary things that I have to download on my computer to start programming?????

#

I am new here

@rocky dragonI personnaly would go with model/view, but you can also set a button on QTreeWidgetItem. it's slower but if you don't have a big tree it's fine

I'm trying to use tkinter to make a little graphing calculator-type thing, and I want one of the frames to have a little terminal prompt where I can enter inputs. Could anyone point me towards a good reference for putting a terminal in a tk frame? It just seems to prompt my computer's terminal instead of opening a window inside my program

I've made an example that I think is close to what I ultimately want at https://github.com/Numerlor/recursive-call-tracker/blob/test-branch/recursive_call_tracker/gui/window.py with a window that looks something like this https://i.imgur.com/PswI5Nu.png, probably don't need the button I was thinking of either. How would something like this work in the tree view? Like I mentioned when I looked at the model/view system it looked like I'd have to do the drawing myself and figure out how to lay things out, am I missing some simpler approach to that?

one feature that's missing is hiding intermediate widgets if it's too deep and scrolling through them instead in some way where only one would be active up to a given depth

mighty frigate
#

@rocky dragonI don't know how you can achieve that coloring with a tree

#

like, the background of the parent including the childrens

#

that aside, it's definitively possible. As for hiding intermediate widgets, i'm not sure what you mean by that, but in a tree you have the control of the expand states of its items

#

with QTreeView, you'll probably have to use a delegate and draw the text yourself

#

if trees dont meet your need, then the first solution you were going after is the only way forward, but it's a painful road. You'll have to handle everything yourself

#

its very fast

mighty frigate
#

@twilit lavayou didn't say with what lib nor what for

#

so effectively, no one can help you

twilit lava
#

it was with PySimpleGUI, but I already solved it, I wanted to try this lib today

#

thank u for your attention, in the next time i'll be more straight to the point
