[indigo crane]

that's a question that doesn't come in tkinter specifically ig, its just modularization

[eternal scroll]

ah

Could you assist with it tho?

[indigo crane]

you can put your classes in different modules, and import them to base module

[sinful pendant]

Ohk,

[eternal scroll]

I tried to import it but I get the circular import error

  File "c:\Users\GAMER\Desktop\Python_School_Script\new_test\new_main_flixgen.py", line 29, in __init__
    for F in (StartPage, Page1, page2.Page2):
AttributeError: partially initialized module 'page2' has no attribute 'Page2' (most likely due to a circular import)
PS C:\Users\GAMER\Desktop\Python_School_Script>

wait a sec

i think i see what i can fix

[sinful pendant]

U can do that, the thing is that u allso import tkinter there

[eternal scroll]

yeah ik

[sinful pendant]

😅

[eternal scroll]

sorry that sounds kinda rude haha

[sinful pendant]

Not rude, i thought u were asking

[eternal scroll]

Yeah, im not sure how to get across the circular import

[indigo crane]

can you show your scripts :)

[eternal scroll]

Sure

[sinful pendant]

Circular import?

What does that means

[eternal scroll]

I think its in a cycle of importing

Main.py

Use main statement when u import tkinter in ur program module

[eternal scroll]

Start Page

import tkinter as tk
from tkinter import ttk
from PIL import Image, ImageTk
import page2
from page1 import Page1

LARGEFONT = ("Verdana", 35)


class StartPage(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)

        # label of frame Layout 2
        label = ttk.Label(self, text="Startpage", font=LARGEFONT)

        # putting the grid in its place by using
        # grid
        label.grid(row=0, column=4, padx=10, pady=10)

        button1 = ttk.Button(self, text="Page 1",
                             command=lambda: controller.show_frame(Page1))

        # putting the button in its place by
        # using grid
        button1.grid(row=1, column=1, padx=10, pady=10)

        # button to show frame 2 with text layout2
        button2 = ttk.Button(self, text="Page 2",
                             command=lambda: controller.show_frame(page2.Page2))

        # putting the button in its place by
        # using grid
        button2.grid(row=2, column=1, padx=10, pady=10)

[eternal scroll]

Sorry how could I do that

[sinful pendant]

Whoa so many

[eternal scroll]

Haha 4 files 👀

[sinful pendant]

In my projeacts i packed all classes in to a single file

[eternal scroll]

Yeah ig i could do that, but it would prolly become too crowded in the end for me

[sinful pendant]

Hmm if u have import structure like a tree where there is no loopong of two files importing eachother then u can ise
if __name__ == '__main__': import xyz

[eternal scroll]

oo

but then it says the module isnt defined

  File "c:\Users\GAMER\Desktop\Python_School_Script\new_test\new_main.py", line 51, in <module>
    app = tkinterApp()
  File "c:\Users\GAMER\Desktop\Python_School_Script\new_test\new_main.py", line 29, in __init__
    for F in (StartPage, Page1, Page2):
NameError: name 'StartPage' is not defined

[sinful pendant]

Hmm there moght be issue like that

Then what you can do os that u can make those imports out from ur main statement

[eternal scroll]

could you please give an example

[indigo crane]

oh

[sinful pendant]

Ohk just a sec i give u diagram what i am saying

[indigo crane]

so the easiest solution here is to import the module, and not the object directly

thats not the best solution, but the easiest possible here

[eternal scroll]

then i do like

page1.Page1?

[indigo crane]

https://paste.myst.rs/5leh1tsp

so instead of

from page1 import Page1

# does something with Page1

do

import page1

# does something with page1.Page1

[eternal scroll]

Dang

wait a sec

thats so weird what

[indigo crane]

see that fix

[eternal scroll]

I just copied your code

that you sent from the link

and it works

[indigo crane]

yes

[eternal scroll]

but it uses from import

[indigo crane]

i have modified it

[eternal scroll]

Oh

What did you change?

[indigo crane]

only in main.py

[eternal scroll]

Oh

[indigo crane]

#user-interfaces message

[eternal scroll]

okay

[indigo crane]

same goes for other files

[eternal scroll]

I see

[indigo crane]

see this if you are curious
https://stackoverflow.com/questions/22187279/python-circular-importing

[eternal scroll]

tyy!

alr I will do

tysm @sinful pendant

[sinful pendant]

Haha hope u understand it

Ur code seems lie at first it says in file a, import b and file b at first kine says import a, then in file a it says import b and thing continues like that

[eternal scroll]

Wait I have a last question, If I want to for example change the geometry of the window, how could I do that?

like window.geometry("50x50")

how could I do that here?

[sinful pendant]

I really say i dont remember that much but i know i have used it in my tutorial files

[eternal scroll]

Aha thats okay

[sinful pendant]

https://youtu.be/NytF3pJSMc8 see this

I learned tkinter from his playlist

[eternal scroll]

Haha I dont mean that

I understand how to resize it and stuff

but because we are using classes

[sinful pendant]

No just watch the tutorail there he tells the code in between

[eternal scroll]

Like do you see how he uses root. ?

what do I need to use

[sinful pendant]

Root is same as tk.Tk()

[eternal scroll]

class StartPage(tk.Frame):
    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        root = tk.Tk()
        root.geometry("500x500")
        # label of frame Layout 2

When I do that it opens a new window

[sinful pendant]

I think to resize u use same code but u change dimensions

[eternal scroll]

Im not talking about that

Im taking about

root

because when i do root = tk.Tk()

and change its geometry it opens a new window

Im trying to ask what is this already set as

as its opeaning a new window

[sinful pendant]

U need to put ur window name into a variable

Otherwise it will create new

[eternal scroll]

I tried to set it root

and it didnt work

[sinful pendant]

I see u have different structure, in your classes try asking billyeatcookied

He definitely have answer for u

[eternal scroll]

Okay tysm

||@indigo crane sorry for the ping || If I want to forexample resize the window what would the tk.Tk() be equal to?

[indigo crane]

resize your window? that's a default behavior unless you have configured it

[eternal scroll]

Yeah so for example if I want to do that what would I need to do?

[indigo crane]

a window is resizable by default

you don't have to do anything other than normal instantiation

[eternal scroll]

Like how
root = tk.Tk()
what is root = in my case?

like

what is root for me

[indigo crane]

root is your root window in that case

the main window of your application

[eternal scroll]

Yeah so for me

what would it be?

so I want it

so when I switch frames the gui changes size

and I will set the size

[indigo crane]

you can modify geometry of the window using .geometry()

[eternal scroll]

yeah so what would i put before .geometry()

[indigo crane]

your window

root in this case

[eternal scroll]

but when i do that

it opens a new window

import tkinter as tk
from tkinter import ttk
import tkinter
from PIL import Image, ImageTk
from page2 import Page2
from page1 import Page1
from startpage import StartPage

LARGEFONT = ("Verdana", 35)


class tkinterApp(tk.Tk):

    # __init__ function for class tkinterApp
    def __init__(self, *args, **kwargs):

        # __init__ function for class Tk
        tk.Tk.__init__(self, *args, **kwargs)
        # creating a container
        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand=True)

        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        # initializing frames to an empty array
        self.frames = {}

        # iterating through a tuple consisting
        # of the different page layouts
        for F in (StartPage, Page1, Page2):

            frame = F(container, self)

            # initializing frame of that object from
            # startpage, page1, page2 respectively with
            # for loop
            self.frames[F] = frame

            frame.grid(row=0, column=0, sticky="nsew")

        self.show_frame(StartPage)

    # to display the current frame passed as
    # parameter
    def show_frame(self, cont):
        frame = self.frames[cont]
        frame.tkraise()


# first window frame startpage
# Driver Code
app = tkinterApp()
app.mainloop()

So in here

if i wanted to resize it

what would i do

[indigo crane]

you can resize it using root.geometry("widthxheight")

for example root.geometry("300x600")

[eternal scroll]

root isnt defined and when I define it, it opens a new widnow

[indigo crane]

in your case app is the main window

you can set geometry for app

[eternal scroll]

  File "c:\Users\GAMER\Desktop\Python_School_Script\new_test\new_main.py", line 19, in __init__
    app.geometry("500x500")

    app = tkinterApp()
  [Previous line repeated 496 more times]
RecursionError: maximum recursion depth exceeded

When I move it close to the top

[indigo crane]

oh

you will have to do it here

app = tkinterApp()
app.geometry("300x600")
app.mainloop()

right after definition, and before entering the loop

or you can also do it inside your class

[eternal scroll]

Does it go in the init

[indigo crane]

yep

something like self.geometry()

you can do

[eternal scroll]

then it says app.mainloop is not defined

[eternal scroll]

This is the code im using

I tried to define app as well out of the init

but then it doesnt run the file

nvm eventually it gets this error

no need to define app inside init

do self.geometry()

[hollow wadi]

Don't know much about the topic but it says to set 'master' kwarg in PhotoImage method

[digital gale]

Almost done my first project creating a gui and I have a couple of questions

Is there any way for me to remove the borders on the buttons to make it look cleaner?

Also is there any way to shrink how much space there is at the top?

When ever I drag the window to shrink it, it always just cuts off the bottom and not the top

[eager beacon]

@digital gale Which library are you using?

[digital gale]

PyQT5

[eager beacon]

Is that what it looks like when you run the python code or when you run the UI in QtCreator/Designer?

[digital gale]

Using the preview function in QT Designer

[eager beacon]

Okay

Look at the main layout in designer, then set the top margin to 0

if its default still, it should say (12,12,12,12)

top is the second value

left,top,right,bottom

Are the numbers displayed on a label up there at the top?

[digital gale]

What do you mean?

[eager beacon]

0123x120312

is that on a label?

[digital gale]

Yes

[eager beacon]

set the vertical size policy to maximum on that label

[digital gale]

Sorry if im being a bit dense but im doing this im Property Editor correct?

[eager beacon]

yes

I don't really use designer but the sizePolicy options should be there

[digital gale]

Just did

[eager beacon]

okay, it should have shurnk a bit... did it?

[digital gale]

Now I don't know where to find this

[eager beacon]

It probably says Form or Widget SomeLayout(GridLayout,HBoxLayout)

[digital gale]

Nope

[eager beacon]

can you send me a screenshot of what the UI looks like in the designer window and include the widget tree on the right hand side?

[digital gale]

Were you talking about these?

[eager beacon]

okay

So, see how centralWidget has the crossed red circle?

That means you don't have a layout on that widget

Right click on centralWidget, go to the layout menu, and choose layout in grid

[digital gale]

Okay

[eager beacon]

so what changed when you did that?

[digital gale]

Did you mean left click?

Right click brings up a menu

[eager beacon]

yeah, you should see an option near the bottom that says something about layout

it should open a submenu when you hover over it

[digital gale]

Nope

[eager beacon]

hang on, let me open something up in the creator

Are you sure you right clicked on centralWidget?

[digital gale]

Yes

[eager beacon]

Those options look like a right click on mainWindow

[digital gale]

Its the opposite

Clicking on main window brings up what you want

Clicking on central widget doesn't

^ Is main Window

[eager beacon]

Oh, I guess thats a special behavior for mainWindow/centralWidget

normally when you add a widget and put something inside of it, you have to click on the widget, not its parent

anyway... what does it look like now?

[digital gale]

Which layout do you think would look best for this?

I tried to use them once and completely failed

[eager beacon]

you have to do grid

[digital gale]

Looks like this now

[eager beacon]

perfect

now click on the layout, set the spacing to 0, and the contentsMargins to 0

[digital gale]

How would I click on the layout?

[eager beacon]

all of the contentsMargins should be 0

if you don't see a layout, click on centralWidget and scroll to the bottom of the properties

[digital gale]

Alright these are the options

[eager beacon]

yeah, set the 9s and 6s to 0

[digital gale]

Looks like this now

[eager beacon]

hm, okay

I assume mainwindow doesn't have any layout options, does it?

[digital gale]

It does

[eager beacon]

no, like the properties I mean

like in your screenshot above

[digital gale]

Correct

There is just QWidget and QMainWindow

[eager beacon]

click on one of your buttons and see what the size policy is set to

[eager beacon]

okay, use the property tree above the properties to select all of your buttons

then go down to the properties and try changing the size policy to Expanding,Preferred

[digital gale]

What do you mean by property tree?

[digital gale]

Select all also selects the label but im guessing I can change that later

[eager beacon]

You can control click single widgets to select more than one at a time

or maybe its shift, I don't know what it would be on windows

[digital gale]

Its looking kind of better

[eager beacon]

Okay, so at this point it might be easiest to manually set a minimumHeight on the label

when the label expands downwards the buttons will square up

[digital gale]

I see

This is looking a lot better

[eager beacon]

you could try setting the vertical size policy to preferred, but you might have to break the layout

[digital gale]

I will keep it as is

Is there not a way to make it borderless though?

I have seen it done before with PyQT5

[eager beacon]

I'd increase the font size in the label or make the entire thing a little bit wider so you can make the label smaller but keep buttons square

[digital gale]

I personally like it the way it is

[eager beacon]

You can make it frameless but its a pain to implement, and I don't know how or if you can do it within designer

when you make it frameless, you have to override the mouse events just so you can move the window on your screen

[eternal scroll]

I read it but it didnt work ty tho

[digital gale]

That does seem like a pain

One last question

Is there any way to remove this bar?

[eager beacon]

thats done with the remove status bar option in the right click menu on mainwindow or centralwidget

[digital gale]

Thank you for all your help!

[eager beacon]

or actually... you might just need to select the central widget in the property tree and then drag the little blue dots on the top and bottom of the widget if that doesnt work

drag them towards the window frame

[digital gale]

Nope it just right there in MainWindow

[eager beacon]

that got rid of the space at the bottom and top?

[digital gale]

Hey, I found a code on the Internet which ask me to select an excel and then it displays it on my UI, but as I want to display always the same excel, is there a way to automatically choose the same excel?

In fact what I want to do is to display an excel on my tkinter ui

hey, I got a Qt QMainWindow class and I want to separate all the functions (except the init) from the class into another file, how can I do that?

there are many functions in the class, and the file is getting a bit large

basically I want to define the class and it's initialization, like button presses, combo box changes, etc in one file and all of it's functions that are called by the buttons, text changes, etc separate into another file

if I can separate them into multiple files it would be awesome

[rocky dragon]

you can define the GUI in a QMainWindow class and then subclass that to implement your behaviour

something like these two files https://github.com/Numerlor/Auto_Neutron/blob/settings-rework/auto_neutron/windows/gui/main_window.py https://github.com/Numerlor/Auto_Neutron/blob/settings-rework/auto_neutron/windows/main_window.py

Hello is it possible to make a rounded window in tkinter? like for windows 10 for example with rounded corners

pls ping if you respond

[drowsy wedge]

well.. i use pysimplegui which is easier and have things called popups, popups have a property called no_titlebar which is as it name suggest removes title bar which makes customization it easier i think but this is NOT REALEATD TO MUCH about TKINTER OR YOUR QUESTION

[eternal scroll]

haha thank you for your comment tho

[green stump]

I'm developing a software that would allow me to write the phonetic respelling (with english alphabets) of lexemes for non-indoeuropean languages to then convert them to a fitting translation of lexemes written in the native language.

Now i've finished the logic of the translation and the base system but I'm unsure of how to implement the GUI utility that would allow me to use it diversely independent of the software.

Optimally I imagine something like a system that I can enable, write the payload in any application and the system will be able to replace it inside wherever I'm writing in, is it possible? if not what other alternatives should I take?

Hello All
I am just wondering... which gui framework should i choose?

[eternal scroll]

Nah that doesnt work

[cobalt elbow]

I do recommend PyQt

[topaz depot]

I tried it. It does have a lot o controll over the gui. BUT it is not easy to learn (Where do i start?)

[cobalt elbow]

Tkinter or Kivy

and with kivy you can use KivyMD for better interfaces

[willow dune]

They have their own uses honestly. Tkinter is better for flexibility,

[willow dune]

Here is Kivy vs Tkinter and how they differ

[cobalt elbow]

actually I used the both

Tkinter is very very basic

but

if you want more beautiful GUI kivy is the best

and also

with Kivy you can create a mobile app

.apk

[willow dune]

Kivy doesn’t work on Linux it looks like

[cobalt elbow]

no it does work

it's cross plateform

[willow dune]

True, just looked it up. That image I sent isn’t correct then lol. Googles wrong

[cobalt elbow]

hahahahaha

coz am using linux and tried Kivy on it lol

[willow dune]

Kivy has limitations though when it comes to developing mobile apps though, right? I believe I’ve read before that people recommend not writing apps in python because native/kotlin and c/swift provides much more options on what you can do.

[cobalt elbow]

yes of course

native apps are more better and performent

but if we talk Python

Kivy is the best

[willow dune]

Understood!

[oblique umbra]

stupid question but when in pycharm the console at the bottom can it be made to be a seperate window?

[digital gale]

Which library should I learn for simple-ish desktop applications?

I just created my first application in PyQT5 but I found the designer hard to use

[cobalt elbow]

Tkinter or Kivy

[cobalt elbow]

I don't think so

[digital gale]

Does kivy have a designer? I feel like it would be complicated hard coding everything

[cobalt elbow]

yes, it's a hard coding library

I think you want just drag and drop things right ?

[digital gale]

Not entirely but I would prefer not having to write all of the design elements

[cobalt elbow]

hmm I understand

there is one

if you wanna try it

"Pygubu"

its is a python GUI for building tkinter apps

[digital gale]

How hard is it to make applications with kivy?

Maybe I'm over estimating how much I would have to hard code because of pyqt5

A simple calculator gui was 2.6k lines

And it glitched out my pycharm

[cobalt elbow]

wow HAHAHAHAHAHA

[cobalt elbow]

Why are you guys using pycharm for small tasks and projects ?

use VSCode or vim either

Pycharm is for big big projects

[digital gale]

Theres nothing wrong with pycharm

My system can handle it just fine

No point of not using it

It also has better intellisense than vsc

[cobalt elbow]

yes of course

anyway

[cobalt elbow]

try this one

[digital gale]

I will

I'll also check out kivy

Keep my options open

Hello everyone, I'm in the process of doing a gui that should reads the feed of a camera and does some image processing tasks such as an fft. To do so, I've decided to go for pyqtgraph since it's amazingly fast and does an exceptional job at real time stuff. However, I'm having a hard time finding documentation on it. For example now my problem is how to control the ROI, the 1D plot at the bottom, the side slider and change the colormap. One thing that would be useful would be to set a ROI that allows to extract two crossed lines to get the transverse profiles of the image. If anyopne could point me to some examples that do this I would really appreciate it

Can Anybody please help me in embedding a PyqtGraph into a PyQt QFrame widget?

[eager beacon]

What are you trying to use? It shouldn't be any different than adding any other widget.

import numpy as np
from pyqtgraph.Qt import QtWidgets
from pyqtgraph.imageview import ImageView

app = QtWidgets.QApplication()
frame = QtWidgets.QFrame()
view = ImageView()
img = np.random.randint(0, 255 + 1, size=(256, 256, 3))
view.setImage(img)
layout = QtWidgets.QVBoxLayout()
frame.setLayout(layout)
layout.addWidget(view)
frame.show()
app.exec_()

[digital rose]

This is how i created my frame inside the mainWindow Class (PySide2),

        self.temp2_page_mainFrame.setFrameShape(QtWidgets.QFrame.StyledPanel)
        self.temp2_page_mainFrame.setFrameShadow(QtWidgets.QFrame.Raised)
        self.temp2_page_mainFrame.setObjectName("temp2_page_mainFrame")```
Now i want the following example graph from pyqtgraph.examples to be embedded into this frame
```import pyqtgraph as pg
import numpy as np
from time import perf_counter
import time

win = pg.GraphicsLayoutWidget(show=True)
win.setWindowTitle('Temperature Plot')

chunkSize = 100
# Remove chunks after we have 10
maxChunks = 10
startTime = perf_counter()
win.nextRow()
p5 = win.addPlot(colspan=2)
p5.setLabel('bottom', 'Time', 's')
p5.setXRange(-10, 0)
curves = []
data5 = np.empty((chunkSize + 1, 2))
ptr5 = 0


def update3():
    global p5, data5, ptr5, curves
    now = perf_counter()
    for c in curves:
        c.setPos(-(now - startTime), 0)

    i = ptr5 % chunkSize
    if i == 0:
        curve = p5.plot()
        curves.append(curve)
        last = data5[-1]
        data5 = np.empty((chunkSize + 1, 2))
        data5[0] = last
        while len(curves) > maxChunks:
            c = curves.pop(0)
            p5.removeItem(c)
    else:
        curve = curves[-1]
    data5[i + 1, 0] = now - startTime
    data5[i + 1, 1] = np.random.normal()
    curve.setData(x=data5[:i + 2, 0], y=data5[:i + 2, 1])
    ptr5 += 1


def update():
    update3()

timer = pg.QtCore.QTimer()
timer.timeout.connect(update)
timer.start(50)

if __name__ == '__main__':
    pg.exec()

Note: The graph example code is in a different .py file, I will need to import this into my main.py file where the frame is.
Thanks for your help

I guess you'd import win from whichever example that is and add that to the layout that your frame uses

[brisk mesa]

what framework do u guys recommend for gui ?

[hardy island]

In python - tinker or a wrapper around it, called pysimplegui . These should be more than enough for most graphic interfaces.

[brisk mesa]

thank you !

i was looking at pyqt5

[hardy island]

By default, tkinter is already downloaded with py3.X . Usually shortened to tk .

If you're just starting out, or need a basic gui - pysimplegui would do.

Its beginner friendly, and shortens some calls of tkinter and help creating the interface faster.

hi! i have come across some problem which i can't really figure out the solution of... so. I am making a music player (similar to MusicBee) and i really want to achieve fade in and fade out effects after unpausing and pausing... the thing is that i want to keep my ai responsive while doing that (the fades would not be longer than like 0.6 s). For sound output I'm using QAudioOutput and QMediaPlayer for player. I tried multithreading with QThread, trying to keep my main window responsive, but it's not working as i want to and i got some errors which i don't really know how to fix, even after thorough google search. The thing is that i have two functions that would gradually set volume lower during the designated fade period (0.6 seconds max) and that bugs my ui when i try pausing or unpausing during that time. If any of you have come across a problem like this, I would really appreciate your help! :)

[wary birch]

Hi, I need some help with handling pyqtgraph inside PyQt5. Since I'm a newbie in pyqtgraph, I decided to do a small "hack" so as to be able to handle better the positioning of the plots. So I want to place 4 plots in a grid of 2x2, and what I did was to wrap a PlotItem inside a QWidget, and then use a QGridLayout since I already some familiarity with that layout. This is how I defined my new Plot widget:

class LinePlot(QWidget):
    def __init__(self):
        super().__init__()
        
        self.global_layout=QVBoxLayout(self)
        self.global_layout.setContentsMargins(0,0,0,0)
        #Create line plots
        self.plot=pg.GraphicsLayoutWidget(self)
        self.plot.setContentsMargins(0,0,0,0)
        self._plot=pg.PlotItem()
        self.line=pg.PlotDataItem({"x": [],
                                    "y":  []}, pen=pg.mkPen('g', width=1))
        self._plot.addItem(self.line)
        self.plot.addItem(self._plot)
        
        self.global_layout.addWidget(self.plot)

However, I'm now experiencing a somewhat serious problem: if I resize my window with all these plots, even if I'm not updating them in real time, or have anything plotted on them, it may crash my app. I assume that this may not have happened if I had used the pyqtgraph native layout system, but I could really use some input

[low scarab]

@wary birch pyqtgraph.GraphicsLayoutWidget allows easy grid layouts. see for example pyqtgraph/examples/scrollingPlots.py

@wary birch however, using pyqt layout widgets should be fine; I use QGridLayout all the time.

@wary birch it really is worthwhile to run all the pyqtgraph examples as you're starting out; get a sense of what's possible, and then know to go look at the source when you want to build something similar.

• WITHOUT LAYOUTS *

[rocky dragon]

why without layouts?

[dense rock]

idk

hmm

I want more control

over the widgets

ig

but yes later like after 1 week me gonna learn grid layout

cause it is gonna be my main layout ig

[dense rock]

well is it possible ?

[rocky dragon]

probably if you handle the repositioning manually, definitely would be easier with a scrollable layout in the widget

[dense rock]

ok

I am assuming cli related stuff will also be asked here. So basically I need to choose a library for the cli parsing and another library for sweet terminal progress-bars and table display. In a way I would prefer to keep dependencies to a minimum so I dont end up with more libs related to cli stuff then the actual program.

For cli, I need ability to nest parser/commands and let parsers written in another file "register" themselves and extend the cli seamlessly.
For the cli parsing, the options I could find were

argparse (python stdlib, I remember having a horrible time with subparsers)
docopt (does not seem exactly maintained or "extendible")
cleo (no idea, but seems to provide a lot of stuff and used by poetry too)
click (seems to be popular, used by httpx)
typer (click but with typehints instead of decorators I guess?)

No idea if I am forced into using progressbars and colours and stuff of one of the last 3 libs or I can use rich/tqdm/etc ones.

For pretty terminal I would prefer good looking and one I can control without poking around too much. The ones I had found are,

tqdm
rich
alive-progress

• colorama obviously

[sick carbon]

I haven’t used any, but Rich, Textual and Colorama are mentioned often

how to create really beautifuls tools(software GUI)? module? please ping if you response

[neon trail]

hello friends! = )

pyqt5 question -
is it possible to embed/show a QWidget inside of a QGraphicsView / QGraphicsScene (however that works)

basically, my app works like this -

1. i have my main pyqt5 app. using a menu option, i popen a subprocess, grab its window handle, and shove that external window into a QWidget.
2. from there i am placing that widget into a tab in a QTab, and can present the external app properly (effectively embedding that subprocess into my app)
3. i am then layering in some object detection, and "drawing" the matches back onto the subprocess window housed in my main app (think overlays), using additional transparent and click-through-able colored QWindow objects

if possible, i would like to instead trade the QTab for a QGraphicsView/Scene, so i can have better control over the drawing of the overlays

i have also considered using QStackWidget/Layout, but have not been able to get it to work properly.

any advice is welcomed! 🙂

i used pyqt designer to build a really really simple app

but i want to expand it, make something like this with various tabs on the left side

Qt isn't exactly beginner-friendly, but it is the best overall. So if you've already started using it and you're happy with it, there's no point learning another framework, there's nothing they can do that Qt can't

hey guys im new to python and have to create a gui calculator using tkinter
https://pastebin.com/phFPfQJ2
thats what ive done but i havent created 2 buttons that are supposed to do cm - inch / inch - cm conversions and I also have to make the background a light blue colour, im unsure of how to do this and where to insert those things into my code. the tutorials i watched werent very clear to me as the way each person was creating their calculator was different. I have to have this created by in the next 12 hours so any assistance would be really appreciated. its been giving me a headache lmao

[prisma falcon]

Hm ok, and should i use designer? or code everything myself?

[prisma cloak]

any python packages you guys would recommend for having draggable elements on a canvas?

[stray jackal]

good question

[brazen thicket]

(I'm not familiar with Qt, but I've used designers for other GUI stacks)
A designer is a timesaver for making apps quickly and it's also a great learning tool, if you pay attention to a few things:

• The Property menus are great for finding out what's possible, use them to experiment with stuff. They'll teach you what properties a widget has, so it will be easy to find them again when you're writing code directly.
• Make a habit of reading the code generated by the designer, so you know what does what and you'll feel comfortable editing it if needed.
• Paradoxically, the weak point of designers is layout. When you drag a widget to some place on the screen, and drag its corners to resize it, the designer doesn't know your intent: did you want an absolute position, or aligned with something else? what should happen if the content becomes too big, or the user resizes the window? You'll need to learn widget positioning and reflowing yourself, so you can make changes if the designer doesn't do what you want.

Hello I'm experiencing some issues regarding PyQt5.
Code: https://paste.ofcode.org/Mh3ipd8dXBjEHDMzgQua2C

I have four QLineEdit()'s where the user will enter a data,
I have one QPushButton() where the user's data will be transferred to the Calculation class.

Everything goes very well until line 116 where the UiTable() is called, the table itself is never shown for some reason. There are no errors but the debug prints is showing that it goes well

I think it might be that I call self.show() two times, once in line 43 and once in line 149. If that's the issue, how would this be solved?

Any kind of help will be appreciated, if you want to run the script yourself to see what's going on, feel free to do so! 😛

[agile spade]

what would recommend, Dearpygui or Pysimplegui?

[sick carbon]

They are quite different, so it depends on what you need. What are your requirements?

[sick carbon]

Dear PyGui supports this. For example, see
https://github.com/Magic-wei/DearBagPlayer#drag-to-plot

It also provides a node editor, see
https://github.com/hoffstadt/DearPyGui/wiki/Dear-PyGui-Showcase

[prisma cloak]

oo dearpygui actually looks like my best bet, instead of duct-taping tkinter extensions into a pysimpleguitk or pysimpleguiwx thing

[sick carbon]

I wouldn't know about the other libraries, but Dear PyGui supports it. Another basic example @prisma cloak

https://github.com/Mstpyt/DPG-Examples/blob/main/drag_and_drop_project_chart.py
(should work, I haven't tried)

Be sure to check out the API documentation
https://dearpygui.readthedocs.io/en/latest/index.html

Discord is best for support
https://discord.gg/tyE7Gu4

After installing Dear PyGui, be sure to run the built-in demo. It has an example of drap and drop as well.
https://dearpygui.readthedocs.io/en/latest/tutorials/first-steps.html#demo

[brazen thicket]

I wouldn't recommend pysimplegui.
As soon you get beyond something completely trivial, the code becomes an ugly mess of nested lists.
It uses tkinter or qt behind the scenes, but doesn't do a very good job of covering all their features, so you may need to learn both pysimplegui, the framework underneath it, and how to get the two to play nice.
The documentation is very imcomplete.

[edgy kestrel]

Hey, im using PyQt to make an GUI app for windows. I need to have a visually transparent window that doesn't allow clicking other apps through the transparent regions, how would i do this?

setWindowFlags(Qt.FramelessWindowHint)        setAttribute(Qt.WA_TranslucentBackground)```These two flags are enough for transparency but it has the forementioned problem

[edgy kestrel]

Possible workaround but seems kinda clunky, having background color on all elements with very low opacity seems to capture all the mouse events

Nvm, I found it. Had to go to the internal Qt layout and use .setContentsMargin(0,0,0,0) within the GraphicsLayoutWidget

[swift halo]

Am I correct that creating tkinter.Variables is not thread-safe? 😬

because this is what it does ```py
global _varnum
...
else:
self._name = 'PY_VAR' + repr(_varnum)
_varnum += 1

so if I create two variables in two separate threads, there's a chance that they will get the same name, right?!

I guess I can pass my own name and guard the generation with a lock or something

also, nice debugging print... https://github.com/python/cpython/blob/main/Lib/tkinter/__init__.py#L390-L392

hey, I have a very basic question regarding UI. How do you design UI for any software? Should I be using some UI design apps like figma? How do i integrate figma ui with python code?

[digital rose]

Hello I would like to do a ui with tkinter so open programs with buttons do you have any suggestions?
when i want to open the programs it doesn't find the path

[boreal pier]

I used kivy it’s hard to grasp at first then it gets better, lots of features but little documents regarding help, the documentation is good though

[sour wadi]

I’ve seen that lambdas are typically used to pass extra arguments through Qt slots. I’m just curious as to why a lambda is need to pass ANY arguments. Is it simply because Qt just ignores whatever argument you put inside the slot function and that’s just how it is?

[tribal path]

a lambda is a callable, calling a function ie func(args) would just assign the returned item

[buoyant fulcrum]

Hi guys, I am using tkinter. Would you say this is a bad layout?

How could I improve it?

(the add button would create a new block every time you press it)

[sudden coral]

Depends on the average use case. If a lot of blocks are added, it would become difficult to navigate since it would be a lot of scrolling and no visual distinction between blocks

One alternative is to show a modal or separate page when adding a new device, which shows the form for that device. The device will get added once that form is filled in and the user pressed some submit button.

You could then add a dropdown menu with a search bar to select a certain device to view details of, edit, or delete.

But if you only anticipate like 3-4 devices then your layout is probably okay, except perhaps for the inability to delete a specific device.

[oak sand]

anyone here well-versed with PyInstaller?

[sour wadi]

Sorry, would you be able to expand on that?

[tribal path]

!e

x = lambda: print(123)

things like slots or commands in tk take callables, ie x and are called with () based on say the signal

[hidden nest]

I just started making GUIs and I ran into a small issue when trying to make my first own GUI using tkinter. The program is supposed to make a window in which there is a counter that starts from 0 and it goes up and down and resets with "Increase", "Decrease" and "Reset" buttons. Additionally the window closes and the program stops running from "Quit" button.
The GUI is made with the following code:

class Counter:
    def __init__(self):
        self.__main_window = Tk()
        self.__number = 0

        self.__current_value_label = Label(self.__main_window, text=f"{self.__number}", relief=FLAT)
        self.__current_value_label.pack()

        self.__reset_button = Button(self.__main_window, text="Reset", borderwidth=2, relief=RAISED, command=self.reset)
        self.__reset_button.pack(side=LEFT)

        self.__increase_button = Button(self.__main_window, text="Increase", borderwidth=2, relief=RAISED, command=self.increase)
        self.__increase_button.pack(side=LEFT)

        self.__decrease_button = Button(self.__main_window, text="Decrease", borderwidth=2, relief=RAISED, command=self.decrease)
        self.__decrease_button.pack(side=LEFT)

        self.__quit_button = Button(self.__main_window, text="Quit", borderwidth=2, relief=RAISED, command=self.quit)
        self.__quit_button.pack(side=LEFT)

        self.__main_window.mainloop()

And the methods it calls inside the commands are as follows:

    def reset(self):
        self.__number = 0

    def increase(self):
        self.__number += 1

    def decrease(self):
        self.__number -= 1

    def quit(self):
        self.__main_window.destroy()

Right now the counter inside the window doesn't get updated from the buttons. There must be something wrong with the contains of the methods. Quit works just fine.

How would I go about making something similar to Unreal Engine's event editor in python? (basically a canvas on which you can place blocks and connect them with "wires")

[raven tundra]

Hey guys. I'm a noob and not really sure how to ask this question so bear with me. I know it's somewhat common for desktop gui applications to be written in HTML/CSS/JS nowadays. (I'm referring to like Electron) - is there any easy way to stack something like that on Python? Even some more narrow Google search terms would help me out because I can't find a thing

[eager beacon]

This seems to be popular https://github.com/ChrisKnott/Eel

You'd probably be better off just using electron if you're set on using JS

@raven tundra if you're looking for something like the declarative views in React and still want to be able to use Python you should check out QML

[buoyant fulcrum]

Thank you!

I'm thinking of doing something like this, which if I limit to 10 devices, hopefully scrolling won't be an issue

and then I can add ability to delete devices or edit their details next to each block

I was just worried about it being unusable or looking like a mess

Does anyone work with kivy before?

I would like to know can kivy drop the GIL in multithreaded code? While I want to do some image processing stuff, but don't want to make GUI unresponsive at that time, I want to visualize with wheel movement in the UI so that to make understand that something happening or processing at the background. So can kivy drop the GIL in multithreaded code?

[sick carbon]

I think you are looking for a node editor. The Dear PyGui framework has support for node editors built in. There is a bit of a learning curve, but it's possible. See the following two implementations as examples.

Example 1: a simple example (compatible with the latest version of the API)
https://github.com/hoffstadt/DearPyGui/wiki/Dear-PyGui-Showcase#heron-a-hybrid-approach-to-data-pipelines-in-python

Example 2: an extended example (not compatible with the latest version of the API)

[rain quarry]

Is there a way to have dear pygui use the GTK context for styling?

@sick carbon

[sick carbon]

I have not heard aobut that before. What did you have in mind?
Dear PyGui has its own theming system.

[rain quarry]

well. the dear pygui framework seems to have a very specific design, unlike UI frameworks like tkinter or qt which follow your system's GTK settings

[sick carbon]

You are right about that. Dear PyGui renders everything itself, independent of the OS. You can change the fonts, colours, rounding, spacing, etc. to change the look of an app, but it will not inherit the settings of the OS.

[rain quarry]

yikes

do you happen to know how to accomplish what I'm looking for with Qt or TKinter or any other framework that does follow the OS?

[sick carbon]

Qt might have a node editor as well. I wouldn’t expect Tkinter or WxPython to have a node editor. @rain quarry

[eager beacon]

Qt doesn't have a node editor but there is a super nice one on github https://github.com/jchanvfx/NodeGraphQt

[vital dome]

Hi, saw your question.

There is actually a way to change the bottom icon on the taskbar in windows.
Let's assume that you have a very simple tkinter code:

from tkinter import *
root = Tk()
root.mainloop()

You can see the default icon on your taskbar.

Next, simply put your ico icon file in the same folder as your python file.

Add the following code at the very start of your program:

import ctypes
ctypes.windll.shell32.SetCurrentProcessExplicitAppUserModelID(YOUR_ICO_ICON_FILE_NAME)

You can then see the icon on your taskbar changed to your ico file icon.

Hope it helps! :D

How can I display html content in my gui? So if I would be making my own webbrowser

[rocky dragon]

Qt provides a text widget with some html support, or its webengine that I believe uses chromium

[cosmic hamlet]

Ah ok nice thanks

[vital dome]

Assuming you are using python tkinter, there are two options:

Tkinterweb. If you are viewing simple websites, this will be the best option. Simply install it using pip install tkinterweb. A simple program will go like this:

import tkinterweb
import tkinter as tk
root = tk.Tk()
frame = tkinterweb.HtmlFrame(root)
frame.load_website(YOUR_WEBSITE)
frame.pack(fill="both", expand=True)
root.mainloop()

Warning: The websites you visit will simply look like in IE or worse.

Cefpython. Something that I think will fit your needs, cefpython is a full-blown chromium browser embedded in Tkinter. An example can be found here: https://github.com/cztomczak/cefpython/blob/master/examples/tkinter_.py. Sadly, it does not work on newer versions of python so I couldn't test it out.

Thanks, Ig I will stick to qt tho since I want the websites to look good

(pyside2) I have a lable with an editable flag, how can I capture when an edit has been made

        label = qtw.QLabel(parent)
        label.setStyleSheet(
            "QLabel {\n"
            f"    background: {'#3B674C' if isinstance(process, Trigger) else '#435776'};\n"
            "    color: white;\n"
            "    width: 130px;\n"
            "    padding: 3px;\n"
            "    border: 1px solid #3B674C;\n"
            "    border-radius: 10px;\n"
            "}"
        )
        label.setText(process.title)
        label.setTextInteractionFlags(qtg.Qt.TextEditorInteraction)```

[vital dome]

Hi, so sorry I do not have any experience with pyside2. I'll try my best to help though.

I've dug through the docs and I think this may help: https://doc.qt.io/qtforpython-5/PySide2/QtWidgets/QLabel.html#PySide2.QtWidgets.PySide2.QtWidgets.QLabel.setTextInteractionFlags

If not, I also came across this question while researching which may help: https://stackoverflow.com/questions/23370261/pyqt-check-if-value-of-qlabel-changed

Once again, I'm so sorry if this answer is not useful - but I hope it is.

[final breach]

I've put snip in column 40/100, but it keeps going outside of the window, why is this happening?

if I put it to 50/100, it completely goes to the otherside of the window and causes problems there

[vital dome]

can i see code?

[final breach]

snipbutton = PhotoImage(file = 'snipbutton.png')
s_btn = Label(image = snipbutton, borderwidth = 0)
s_btn.grid(column = 40, row = 1)

[vital dome]

no i mean the whole code

i need to see the structure of the ui

[final breach]

root = Tk()
root.title('SnipOCR')
root.geometry('600x190')
canvas = Canvas(root, width = 600, height = 190, highlightthickness = 0)
canvas.grid(columnspan = 100, rowspan = 100)
canvas.configure(background = '#303030')
root.resizable(False,False)

root.iconbitmap('logosnip.png')

blueberry = PhotoImage(file = 'blueberry.png')
img = Label(image = blueberry, borderwidth = 0)
img.grid(column = 50, row = 99)

text = PhotoImage(file = 'text.png')
text_img = Label(image = text, borderwidth = 0)
text_img.grid(column = 45, row = 55)

mt = PhotoImage(file = 'ny.png')
mt_img = Label(image = mt, borderwidth = 0)
mt_img.grid(column = 50, row = 55)

snipbutton = PhotoImage(file = 'snipbutton.png')
s_btn = Label(image = snipbutton, borderwidth = 0)
s_btn.grid(column = 40, row = 1)```

[vital dome]

ok giveme a sec to test it brb

Electron is an HTML based GUI for Python.

[paper sundial]

use tkinterhtml

btw u cannt make webbrowser with tkinter html

use selenium for local html (gud for webbrowser i think)

[royal phoenix]

        self.home = QPushButton("Home", self)
        self.home.setStyleSheet("QPushButton { margin-top: 5; border: none; border-top: 2 solid #ccffcc; border-radius: 10; color: white; } QPushButton:hover { background: #ffccff; color: black; }")
        self.home.setToolTip("Home")

        self.prev = QPushButton("<-", self)
        self.prev.setStyleSheet("QPushButton { margin-top: 5; border: none; border-top: 2 solid #ccffcc; border-radius: 10; color: white; } QPushButton:hover { background: #ffccff; color: black; }")
        self.prev.setToolTip("Prev")

        self.next = QPushButton("->", self)

        self.next.setToolTip("Next")

Why they are on top of each other?
this is PyQt5

[full lion]

Hi, Im watching a pyqt5 tutorial and I dont understand:
sys.exit(app.exec())
Ik what sys.exit does but now why we pass the app.exec() func?

[bleak latch]

For websites what would be a good "human test" to bar account creation? Preferably it would be done without using external services and would be something I can make a lot of variations on to avoid bots being able ot just put in the same answer every time to get past.

[cosmic hamlet]

Hi, how can I make my gui scale in PyQt5? So when resizing the window my widgets also resize

[eager beacon]

set a layout on the windows widget and put the widgets yyou want to scale inside that layout

[vital dome]

The app.exec(), or app._exec() if you are using Python 2, starts up the event loop and will block until the application quits [see attachment]. If an exit code has been set, exec()will return it after the event loop terminates.

[vital dome]

If I'm correct you are asking a question on websites. Head to #web-development , this is not the right channel.

[bleak latch]

Oh, doi

thanks!

okayy thx

[shy torrent]

I am struggling like hell to get QTableView and QTreeView to resize to the data in any nice way:

• best setting to just get those Widgets to resize the columns and the rows to the data?

• is there a way to get it to resize to the data and also have it be able to resize interactively? When the user clicks and drags the border between columns or rows

There is QHeaderView.ResizeToContents but it seems mutually exclusive to QHeaderView.Interactive.

What I need would be a way to initially (or when new data is added) to resize it to content and then have it resizeable interactively.

When replying please KEEP the Ping, so I get notified

[mighty rock]

You can style some tkinter widgets using the widgets in tkinter.ttk instead and the Style class

[swift halo]

In tkinter, how can I attach some payload to a virtual event?

[mighty rock]

You can do that with a lambda

For any event

[swift halo]

can you show an example?

[mighty rock]

Yes hold on I'm trying to make it interesting

[mighty rock]

Here, have a look at this.

from tkinter import Tk, Canvas, EventType
from time import perf_counter


def clamp(n: float, minimum: float, maximum: float) -> float:
        return min(maximum, max(minimum, n))


def float16_to_color(n: float) -> str:
        return f"#{0xffffff - int(clamp(n, 0, 16) * 0xffff) >> 1:06x}"


class Application(Tk):
    def __init__(self, radius: float = 10) -> None:
        super().__init__()
        self.count: float = perf_counter()
        self.last_x = None
        self.last_y = None
        self.radius: float = radius
        self.canvas: Canvas = Canvas(self)
        self.init()
        self.mainloop()

    def init(self) -> None:
        self.canvas.pack(fill="both", expand=True)
        self.event_add("<<Holding>>", "<Button-1>", "<B1-Motion>")
        self.bind("<<Holding>>", lambda e: self.draw(e, perf_counter()))

    def draw(self, event: EventType, count: float) -> None:
        since: float = count - self.count
        color: str = float16_to_color(since)
        if self.last_x is None and self.last_y is None:
            self.canvas.create_oval(event.x - self.radius, event.y - self.radius, event.x + self.radius, event.y + self.radius, fill=color, outline="")
        else:
            self.canvas.create_line(self.last_x, self.last_y, event.x, event.y, fill=color, width=10)
        self.last_x = event.x
        self.last_y = event.y
        self.count = count


def main() -> None:
    app = Application()


if __name__ == "__main__":
    main()

You can improve it by setting self.last_x and self.last_y to None again in a B1-Release event

[swift halo]

Maybe I don't understand something, but I was asking how to attach a custom payload to an event. Like: widget.event_generate("<<FileReady>>", custom_payload={"file_obj": ...})

I know how to handle events

[mighty rock]

Oh

**{"file_obj": ...}

or just file_obj=...

I guess

[swift halo]

but I can't pass arbitrary kwargs to event_generate

>>> root.event_generate("<<Foo>>", custom_data = 42)
...
_tkinter.TclError: bad option "-custom_data": must be -when, -above, -borderwidth, -button, -count, -data, -delta, -detail, -focus, -height, -keycode, -keysym, -mode, -override, -place, -root, -rootx, -rooty, -sendevent, -serial, -state, -subwindow, -time, -warp, -width, -window, -x, or -y

[mighty rock]

Maybe in data

[swift halo]

I can't find any documentation on what data does.

Event objects also don't have a data field

I came up with this system where I bootleg an event ID via the x coordinate of the event in a thread-safe way... but it seems really overengineered
https://gist.github.com/decorator-factory/34c80257a750c1aafb5ea588a8296922

Basically, I maintain a dict mapping event IDs to payloads. When I want to emit an event, I increment a counter and use that counter to add a new entry to the dict. Then I place the counter value into the x coordinate (or maybe some other attribute of the event).

then I can do ```py
import tkinter as tk
from .virtual_event import VirtualEvent

root = tk.Tk()

@VirtualEvent.listen
def on_foo(event, numbers):
print(f"{event=} {numbers=}")

on_foo.bind(root)

button = tk.Button(root, text="Okay", command=lambda: on_foo.emit([1, 2, 3, 4, 5]))
button.grid(column=0, row=0)
root.mainloop()
``` and on_foo actually receives the list [1, 2, 3, 4, 5]

I understand that I can't put this payload directly into the event, because I can't transform between arbitrary Python objects and Tcl values. But I was wondering whether tkinter had some utility to help out with this

...also without memory leaks

[mighty rock]

https://stackoverflow.com/questions/16369947/python-tkinterhow-can-i-fetch-the-value-of-data-which-was-set-in-function-eve

[swift halo]

right, I can technically extract the data field using some hack

but it will hold a string

. not some arbitrary payload

[rain quarry]

I'm working with PySide2.
I've added a small widget in the bottom left, but ideally it'd be styled the same as the contents of the tab widget (i.e. darker inside). How would I go about copying this without using a custom stylesheet?

And if that's not possible, how would I at least put a clear boundary around it

can someone help plz im a beginner making a pokedex and im struggling to display the images of the pokemon when you click their name in the listbox. As you can see in the pic of my pokemon image file, the pokemon are in in the same order as the names in the listbox and are also distinguishable by the first three numbers of their file name. How do I configure my image label to show whichever pokemon is selected in my clickevent function. I know theres a prtty simple solution im way too tired to see.

heres the code so far dont mind its a bit messy from trial and error

Tkinter is not so good for making games. Why don't you try out pygame? If you still wish to use tkinter, please let me know and I will try to solve your problem.

[rain quarry]

For some reason this tab item isn't setting itself scrollable, any ideas how I can fix that? ```py
def add_tab_widget(self, name: str):
def get():
scroll = QtWidgets.QScrollArea()
scroll.setLayout(QtWidgets.QVBoxLayout())
scroll.layout().setAlignment(QtCore.Qt.AlignTop)
scroll.setVerticalScrollBarPolicy(QtCore.Qt.ScrollBarAsNeeded)
getattr(self, f"configure_{name.lower()}_widget")(scroll) # Add child nodes
return scroll
self.tabs[name] = get # get is called when widget is added

and the code for that group: ```py

def config_iir_group(self, name, label, widget: NodeBaseWidget):
    group = QtWidgets.QGroupBox(label)
    group.setLayout(QtWidgets.QHBoxLayout())
    groupA = QtWidgets.QWidget()
    groupA.setLayout(QtWidgets.QVBoxLayout())
    groupB = QtWidgets.QWidget()
    groupB.setLayout(QtWidgets.QVBoxLayout())

    a = self.node.coeffs_a
    b = self.node.coeffs_b
    current = a + b

    def make_slider(_group: QtWidgets.QGroupBox, _name: str, index: int):
        sub = QtWidgets.QWidget()
        sub.setLayout(QtWidgets.QHBoxLayout())
        sub.layout().addWidget(QtWidgets.QLabel(_name))
        line_edit = QtWidgets.QLineEdit()
        validator = QtGui.QDoubleValidator(-10, 10, 10)
        validator.setNotation(QtGui.QDoubleValidator.StandardNotation)
        line_edit.setValidator(validator)
        line_edit.setText(str(current[index]))
        def complete(*args, **kwargs):
            arr = self.node.coeffs_a + self.node.coeffs_b
            arr[index] = float(line_edit.text())
            self.set_property(name, arr)
        line_edit.editingFinished.connect(complete)
        sub.layout().addWidget(line_edit)
        _group.layout().addWidget(sub)

    for i in range(self.order):
        make_slider(groupA, "A" + str(i+1), i)
        make_slider(groupB, "B" + str(i), i + len(a))
    make_slider(groupB, "B" + str(self.order), 2 * self.order + 1)

    scroll = QtWidgets.QScrollArea()
    scroll.setWidget(group)

    group.layout().addWidget(groupA)
    group.layout().addWidget(groupB)

    widget.layout().addWidget(group)

[peak wigeon]

its not for a game its just the pokedex by itself, i do wana try pygame at some point but this task was set by my teacher lol

[peak wigeon]

i made a little progress but still am not quite there https://pastebin.com/EW2k47Lr

[vital dome]

So basically, I understand that you want to show the Pokémon selected on the ListBox on the right.

Step 1:
Getting the selected option on the listbox.

Before you .mainloop the program, add the code: root.after(0, yourFunctionToUpdatePokemon). This will call the function BEFORE the mainloop starts.

Step 2:
Creating the function.

def yourFunctionToUpdatePokemon():
  while True: #We want to loop this
    time.sleep(1) #Let's check every one second, you can change it if you wish to.
    root.update() #Prevent the program form crashing.
    for item in listbox.curselection(): #We get the index of the item selected
        pass
    # I don't know much about tkinter PhotoImage, but basically you can set the image name 
    # using this simple code
    imageName = (str(str(int(item) + 1).zfill(3))+".png")
    # then set the photoimage to the image name

Step 3:
Remove the M58 and stuff like that behind the image file name.

And done!

Does anyone know the solution to my scrolling issue?

[wraith forge]

I've hit a brick wall on a tutorial of all things.
I'm going through the Qt tutorial stuff for use with PySide6 and I keep running into an error:

https://doc.qt.io/qtforpython/tutorials/qmlsqlintegration/qmlsqlintegration.html The tutorial (if I can get this working it'll be a good place for me to pick it apart and work from there)

The three files that it has you make in (listed in the following order) sqlDialog.py, main.py, chat.qml:
https://paste.pythondiscord.com/payokayaki.py
https://paste.pythondiscord.com/ejehowaroj.py
https://paste.pythondiscord.com/suniroyave.qml

The error it gives me is the following:

QQmlApplicationEngine failed to load component
file:///C:/Users/runner/Python/it_tickets/chat.qml:12:5: SqlConversationModel is not a type

I've hunted all over and I cannot get a straight answer.

[tribal path]

https://doc.qt.io/qtforpython/PySide6/QtQml/qmlRegisterSingletonType.html ?

scratch that, deco should be fine, qml missing an import ChatModel ?

[digital gale]

Quick question, how could I create buttons like these with PyQT5?

When I say "like these" I mean when clicked they stay pressed sort of like a switch and when not pressed they are grayed out

[digital gale]

I'm fine working with bare code or using the PyQT5 designer but I would prefer to use the designer for visualization and easier manipulation

[eager beacon]

You need to add import SqlConversationModel in the QML - this is what's causing the error

then, in ColumnLayout use anchors.fill: parent instead of window

there is also a typo in the ListView delegate
anchors.right: sendByMe ? listView.contentItem.right : undefined should be sentByMe, like in the property.

[eager beacon]

Use a QButtonGroup

https://doc.qt.io/qt-5/qbuttongroup.html#exclusive-prop

[digital gale]

Thank you

[eager beacon]

I think you need to add scroll.setWidgetResizable(True)

[rain quarry]

still no scrollbar when it becomes too big :(

[eager beacon]

hmm.. let me try.

[eager beacon]

Yours is a bit more abstract but this is all you need to do to use a scrollArea.

import random
from PySide6 import QtWidgets
from PySide6.QtCore import Qt


class ScrollArea(QtWidgets.QScrollArea):
    def __init__(self,parent=None):
        super(ScrollArea, self).__init__(parent)
        widget = QtWidgets.QWidget()
        layout = QtWidgets.QVBoxLayout()
        layout.setAlignment(Qt.AlignTop)
        widget.setLayout(layout)
        self.setWidget(widget)
        self.setWidgetResizable(True)


class Widget(QtWidgets.QWidget):
    def __init__(self,parent=None):
        super(Widget, self).__init__(parent)
        self.setLayout(QtWidgets.QGridLayout())
        self.button = QtWidgets.QPushButton()
        self.button.clicked.connect(self.add)
        self.scrollArea = ScrollArea()
        self.layout().addWidget(self.button)
        self.layout().addWidget(self.scrollArea)
        self.scrollArea.setWidgetResizable(True)

    def add(self):
        r = random.randint(1,200)
        l = QtWidgets.QLabel(str(r))
        self.scrollArea.widget().layout().addWidget(l)

app = QtWidgets.QApplication()
win = Widget()
win.show()
app.exec_()

[rain quarry]

Oh I need a setWidget instead of layout.addWidget, is that it?

[eager beacon]

scrollArea needs setWidget(someWidget). someWidget's layout is the layout that you will add widgets to when you move the slider

def floydWarshall(graph): row_names = ["A", "B", "C", "D"] n = len(graph) dist = [[] for i in range(n)] for i in range(n): for j in range(n): dist[i].append(graph[i][j]) for k in range(n): for i in range(n): for j in range(n): dist[i][j] = min(dist[i][j], dist[i][k] + dist[k][j]) print('Najkrotszy dystans pomiedzy kazda para') print("\033[91m A B C D\033[0m") for i in range(n): print("\033[91m{0}\033[0m".format(row_names[i]), end=' ') for j in range(n): if dist[i][j] == INF: print("%7s" % ("INF"), end=' ') else: print("%7s" % (dist[i][j]), end=' ') print()

this is my logic

Hi, Im using PyQt5 rn and I dont understand why the widgets are not getting shown on the layout.
Also when I try to print the children of the layout out its just an empty list.
def window(): app = QApplication(sys.argv) win = QMainWindow() layout = QHBoxLayout() layout.addWidget(QPushButton("Left-Most")) layout.addWidget(QPushButton("Center"), 1) layout.addWidget(QPushButton("Right-Most"), 2) print(layout.children()) win.setLayout(layout) win.show() sys.exit(app.exec())

[eager beacon]

You need to use setcentralwidget on win, then on that widget, set a layout and put the widgets in there

guys

im working on a project and im creating a menu

is any type of way to create an interface that looks cool? it would probably give me some extra credit on it

[cosmic hamlet]

I dont understand, why does it not work this way? I copied the code but left out the class and it didnt work, before it was just a class inheriting from QWidget.

Its exactly the same code

[eager beacon]

Well, its not the exact same code though. Before it was a QWidget. You changed that to QMainWindow(). If you change it to QWidget() it would work like it did before.

QMainWindow lets you do a few things that, like a menu bar across the top off the window, status bar, and you can add dockWidgets to QMainWindow.

[vital dome]

What do you mean by cool?
Something like this?

[rain quarry]

How do I make a pyside2 widget pop out in a new window? I tried just .show as the docs suggested but I couldn't get it to work.

    def popout_widget(self, graph, node):
        main = QWidget()
        main.setLayout(QVBoxLayout())
        widget = QTabWidget()
        node.set_config_widget(widget)  # adds elements to tabwidget
        main.layout().addWidget(widget)
        main.show()

[eager beacon]

I feel like that should work. Are you sure a signal is connected to that method?

[rain quarry]

not a signal but yes it's triggered

actually it might be a signal triggering this callback, not sure

[eager beacon]

Try renaming main to self.popup and see if that works.

[rain quarry]

yup, that did it

[eager beacon]

Okay, that makes sense

Usually when you open a window like that, its a QDialog, and its run with exec()

So if you want a fresh widget every time you trigger the method, you could make a list and stick it in an instance variable, then right after you create main, append main to the list

you can monkeypatch a closeEvent to call self.list.pop() to clear the list when you're done with the widget

it might not be the worst idea to use the pop() to run deleteLater() to make sure it actually gets deleted at some point

I'm a heavy Qt user and I was told tkinter was simpler. I just tried and I probably must have missed a few things because it was kinf od chaotic. Any good ressources for Tk users ?

[sick carbon]

Why use Tkinter if you know Qt?

[mighty frigate]

I was told it was simpler and easier to use with Python

also I was curious

[rocky dragon]

If you're already familiar with Qt I think the only benefit to using Tkinter would be that it's stdlib

[mighty frigate]

is there a ref for tkinter that is not the official website ?

[serene mason]

Hello, I need some help with planning this app out.

I want to make an app that has an alarm, timer and all these functions.
My biggest problem right now is the alarm tab(frame).

I want the user to be able to create many alarms ( similar to iPhone clock app ), and every alarm will be in the same frame..
However, a clear problem with that is that the amount of alarms is dynamic, meaning I would need the labels, buttons and all these functionalities for each alarm to be created dynamically based on how many alarms the user has created. ( Alarms are stored in db )

In summary, how do I dynamically create buttons, labels utilizing some sort of loop in Tkinter and still keep the command functionality working properly?

[rocky dragon]

I don't think there is, maybe docs for Tk itself but I'm not sure how useful those are compared to Tkinter's

[final breach]

can anyone give me feedback

(i just started UI)

[eager beacon]

You can still access effbot with the wayback machine. https://web.archive.org/web/20200703091947/http://effbot.org/tkinterbook

I learnt tkinter from him, it may be useful for you too.

Nice UI! (Just note that blueberry is already a company for screen recorder https://www.flashbackrecorder.com/aboutus)

[rain quarry]

why is it so difficult to find a real-time plotting library that's somewhat decently documented and doesn't have major issues...

If anyone has recommendations please do let me know, so far I've tried:

• matplotlib (too slow)
• pyqtgraph (mem leak and hates scaling)
• pythonqwt (ignores parent widget size)
• vispy (basically doesn't exist yet)

[rocky dragon]

if pyqtgraph is fine otherwise and the widget was handled properly by you then I'd open an issue there and wait for the fix, the development seemed fairly active

[sick carbon]

Have you tried Dear PyGui?

https://github.com/hoffstadt/DearPyGui#plottinggraphing

Datoviz looks promising but still early stages

https://datoviz.org/examples/signals/

[rain quarry]

looks too much like imgui and I;m not a fan of the simplistic look it provides

[rain quarry]

doesn't seem to support qt

[sick carbon]

Sure.

[final breach]

thanks, what should I add to it?

[eager beacon]

Where's the memory leak in pyqtgraph?

[rain quarry]

I assumed PlotDataItem.setData but apparently not according to the dev's tests so I don't even know at this point

[eager beacon]

Oh, you've already created an issue?

Ah, yeah.. I see it

[rain quarry]

all I know is that calling this function is what causes the memory leak```py
def plot_signal(self, audio: np.ndarray):
for i, channel in enumerate(audio):
self.signal_plots[i].setData(channel)

[eager beacon]

I'd assume it's in the Node library.

[rain quarry]

how so? It's just a widget and it's not like there's two of them

[vital dome]

Well, in my opinion, I think you can remove the fade in over here. It looks windows XP-ish.

[vital dome]

You can add a image editor for your snips

[eager beacon]

cant say. I only glanced at the files.

I tired to build the app but I don't have a recent version of xcode

[rain quarry]

What do you need xcode for lol

you just have to do a pip install

[eager beacon]

I followed your instructions and it said I need xcode 12, but thats not available on Mojave

[rain quarry]

Oh wait my setup.py is only configured properly for Linux isn't it

Not sure

Idk how Gradle works on mac

[rain quarry]

Ah

I guess I'll try asking the kotlinlang slack for alternatives

[eager beacon]

too bad that library isn't smaller

it would be easy to switch to PyQt5 and see if the leak is still there

have you tried running that function with some random data ?

[digital rose]

go with PySide6

[rain quarry]

I can give that a try next

[eager beacon]

Its big enough that going from PySide2 to PyQt5 would be a pain. Making it compatible with PySide6 would be too much trouble just to see if it its the qt binding causing the issue

[digital rose]

you should upgrade to either PyQt6 or PySide6 anyway, so... better sonner than never 😉

Qt6 and its PyQt6/PySide6 derivatives are the future... any serious developer should upgrade to Qt6 realm

[eager beacon]

Oh, actually it looks like it does support PyQt5 now.

I'd give that a shot

[digital rose]

what's the issue you're trying to solve, anyway?

[eager beacon]

memory leak

[digital rose]

which version of Python and which exact version of PyQt are you seeing this?

[rain quarry]

3.10.1 and pyside2

The memory leak is only when using the canvas used by pyqtgraph

[digital rose]

what exactly leaks?

[rain quarry]

No clue

[digital rose]

hmmm, got a code to work on?

[rain quarry]

Calling this function is what causes it

The code is at https://github.com/martmists-gh/kaudio-python

[digital rose]

have you considered using the QtMultimedia module of PySide2?

[eager beacon]

@rain quarry Does it happen with the fft widget too?

[rain quarry]

yes

[rain quarry]

can I plot log graphs with that?

I don't see any classes it provides for plotting at least

[digital rose]

oh, sorry, wrong module... QtMultimedia is for sound

[eager beacon]

Honestly, I think spending 5 minutes to change all of the Signals to pyqtsignal would be the best thing you could do

[digital rose]

please read this article, it will give you great insight into plotting in PySide

https://www.pythonguis.com/tutorials/pyside-plotting-pyqtgraph/

use PyQtGraph by installing it: pip install pyqtgraph

[rain quarry]

that's the library I already use though

which has the memory leak issue

did you even read my problem lol

[digital rose]

how exactly are you detecting the memory leak?

[rain quarry]

htop

[rain quarry]

here's the original video

[digital rose]

ah, I see... just saw the video... but why do you think you're experiencing a memory leak just by having a huge memory usage?

please read this...

Updating the plot
While you can simply clear the plot and redraw all your elements again, this means Qt has to destroy and recreate all your QGraphicsScene objects. For small or simple plots this is probably not noticeable, but if you want to create high-peformance streaming plots it is much better to update the data in place. PyQtGraph takes the new data and updates the plotted line to match without affecting any other elements in the plot.

To update a line we need a reference to the line object. This reference is returned when first creating the line using .plot and we can simply store this in a variable. Note that this is a reference to the line not to the plot.

my_line_ref = graphWidget.plot(x, y)

[rain quarry]

because it keeps going up until my system runs out of memory

[digital rose]

how exactly are you updating your plot?

[rain quarry]

effectively using my_line_ref.setData(yData)

[digital rose]

To update a line, we need a reference to the line object. This reference is returned when first creating the line using .plot, and we can simply store this in a variable. Note that this is a reference to the line, not to the plot.

my_line_ref = graphWidget.plot(x, y)

Once we have the reference, updating the plot is simply a case of calling .setData on the reference to apply the new data.

[rain quarry]

yeah that's what I do

[digital rose]

https://www.pythonguis.com/tutorials/pyside-plotting-pyqtgraph/#updating-the-plot

please read this Updating the plot section of the article

[digital rose]

I have a feeling you're doing something wrong

[final breach]

What should I do with the buttons?

[final breach]

What do you mean

[rain quarry]

If that's the case I'd love to know what I'm doing wrong

[digital rose]

please compare this code example with your own code...

[eager beacon]

PyQt5!

[digital rose]

from PySide2.QtWidgets import QApplication, QMainWindow
from PySide2.QtCore import QTimer
import pyqtgraph as pg
import sys
from random import randint

class MainWindow(QMainWindow):

    def __init__(self):
        super(MainWindow, self).__init__()

        self.graphWidget = pg.PlotWidget()
        self.setCentralWidget(self.graphWidget)

        self.x = list(range(100))  # 100 time points
        self.y = [randint(0,100) for _ in range(100)]  # 100 data points

        self.graphWidget.setBackground('w')

        pen = pg.mkPen(color=(255, 0, 0))
        self.data_line =  self.graphWidget.plot(self.x, self.y, pen=pen)

        self.timer = QTimer()
        self.timer.setInterval(50)
        self.timer.timeout.connect(self.update_plot_data)
        self.timer.start()

    def update_plot_data(self):

        self.x = self.x[1:]  # Remove the first y element.
        self.x.append(self.x[-1] + 1)  # Add a new value 1 higher than the last.

        self.y = self.y[1:]  # Remove the first
        self.y.append( randint(0,100))  # Add a new random value.

        self.data_line.setData(self.x, self.y)  # Update the data.

app = QApplication(sys.argv)
main = MainWindow()
main.show()
app.exec_()

[rain quarry]

do I just replace all pyside2 imports with pyqt5?

[digital rose]

yes

[rain quarry]

thank god it's that simple

[eager beacon]

Yeah, and all Signal with pyqtSignal

[digital rose]

in the code example, there's no Signal needing to be changed to pyqtSignal

[eager beacon]

The code is more than what has been posted in this chat

[digital rose]

but you can decorate the update_plot_data() method with Signal() (if using PySide) or pyqtSignal() (if using PyQt)

[eager beacon]

Slot()

[rain quarry]

did you even look at my codebase

[digital rose]

nope

where is it?

[rain quarry]

TypeError: addWidget(self, QWidget, stretch: int = 0, alignment: Union[Qt.Alignment, Qt.AlignmentFlag] = Qt.Alignment()): argument 1 has unexpected type 'NodesPaletteWidget' @eager beacon

[eager beacon]

Is that coming from your python_src folder?

[rain quarry]

which is from from NodeGraphQt import NodeGraph, setup_context_menu, NodesPaletteWidget

[eager beacon]

hang on. Let me check something

[digital rose]

is my code example working for you, @rain quarry ?

[eager beacon]

Can you try using 5.12?

[digital rose]

pip install --upgrade PyQt5

the latest version of PyQt5 is 5.15.6

[eager beacon]

This package follows version recommendations from here: https://vfxplatform.com/

Movie studios really hate bugs so they are always a couple of years behind on the newest version

this is the one I have installed

[eager beacon]

Yeah, could you try using 5.12?

[rain quarry]

oh wait I see the issue

Qt.Py defaults to PySide2 if installed

[eager beacon]

well.. wasn't it working with PySide2 before?

[rain quarry]

yeah but I'm trying to use pyqt5 now

but that means I need to uninstall pyside2

[digital rose]

5.15.6 is the newest version of PyQt5 right now... try your code with the updated version of PyQt5 and let us know what happens

you don't need to uninstall PySide2

[eager beacon]

Maybe if you import PyQt5 before NodeGraphQt they will detect that its been loaded

[rain quarry]

Traceback (most recent call last):
  File "/usr/lib/python3.10/site-packages/NodeGraphQt/widgets/nodes_palette.py", line 50, in paint
    painter.drawRoundRect(base_rect,

``` looks like nodegraphqt doesn't like pyqt5

[digital rose]

change the drawRoundRect to drawRoundedRect

[rain quarry]

I can't, it's a library

[digital rose]

...Rounded...

3rd-party?

[rain quarry]

yeah

[digital rose]

ah, I see

[rain quarry]

and nodegraphqt uses Qt.Py which should have made it so it's all the same but apparently not

[digital rose]

are you using venv? or is PyQt5 installed in your site-packages folder?

[rain quarry]

site-packages

[digital rose]

ha! no wonder you can't get it to work using PyQt: it says very clearly that NodeGraphQt is a node graph framework that can be implemented and re purposed into applications that supports PySide and PySide2.

[rain quarry]

ah, I see

[digital rose]

the first thing they say: https://freesoft.dev/program/101639727

[rain quarry]

well, guess we can't test on pyqt5

[digital rose]

nope, we can't

can you give me a link to your repo and I'll download your code and test it

[rain quarry]

https://github.com/martmists-gh/kaudio-python

you'll need to do a pip install in the root folder first

[digital rose]

what are the dependencies?

[eager beacon]

It says it supports PyQt5...

weird

The only place they use that method is in nodes_palette.py

[rain quarry]

see python_src/requirements.txt

[eager beacon]

you can try to change it to drawRoundedRect and hope for the best

[digital rose]

@rain quarry the requirements.txt file should be put in the root folder of the repo, not in a subfolder (like python_src)

[rain quarry]

it's because the root contains native code and the entire app is in python_src lol

[digital rose]

that's a convention

[rain quarry]

I'm trying to avoid mixing source roots because that way I can use intellij and pycharm separately without it being a pain in the ass and complaining about the .idea files being used by two IDEs at the same time

[digital rose]

it doesn't matter where the actual code of the app is, the requirements.txt file should be put in the root of the repo (besides README.md, and those files)

that's a GitHub convention

just like .gitignore is in the root

please follow GitHub convention

[rain quarry]

¯_(ツ)_/¯

the dependencies aren't necessary for the native part though, otherwise that'd have a separate requirements.txt

instead of complaining how everything isn't up to your personal preferences you could also just help

[eager beacon]

Did you try changing the code in that method to drawRoundedRect?

[digital rose]

there should be only one requirements.txt file for a project, and it should be placed in the project's root dir

that's a GitHub convention

[rain quarry]

there's two projects here, that's what I;ve been saying

there's the native code and there's the app

[rocky dragon]

there's no "github" convention

[digital rose]

yes, it is

[rocky dragon]

and most projects will have multiple requirements files

[rain quarry]

I can't, it's in site-packages

[eager beacon]

You can

[rain quarry]

ehh, I'd prefer not to edit it

vim isn't the greatest tool for editing large projects

[digital rose]

use Sublime Text 😉

[rocky dragon]

could try to patch it then

[rain quarry]

sublime can't edit root-protected files

[eager beacon]

what?

It should be in venv/lib/python3.8/site-packages/PyQt5 if you are using a venv

[rain quarry]

I don't use venvs

[digital rose]

what do you mean by root-protected files?

[rain quarry]

well
