uughhhh....in less than 20 words?

[swift vault]

Its a framework that allows to print left, center and right oriented text using a theme for different presentation

[elfin stirrup]

interesting

I'm sorry for the stupid question, but why?

(feel free not to answer)

[swift vault]

I love console, and think we're missing a proper "TUI" (aka that does not try to mimick a GUI).
Though, I think it's like 20-25 years "too late" 😅

[elfin stirrup]

oh, this is interesting.

well, thank you! good luck!

[swift vault]

goal is to simplify console output,and make it more... appealing.. to endusers, while keeping it simple to use for coders

[elfin stirrup]

yeah, that's cool

[swift vault]

thank you 🙂

Pseudocode:

# I'm using ``// 2 * 2`` to make it an even int number.
width_work = dialog.width // 2 * 2 / 2
width_box = input_box.width // 2 * 2 / 2

# Asuming anchor for input_box is lower left:
input_box.pos = width_work - width_box```

[misty canopy]

// 2 * 2 / 2 looks slightly weird to me anyway, since it's just //2 but as a float

```my bottom sheet isnt really showing
this is all the code i have relating to that
what could be the cause?

[somber hemlock]

(general advice on avoiding global variables)

[lucid cedar]

;-; yea i pretty much didnt know about the fact that i can use oop until i was deep into the project, so it's pretty much just nested functions, and i cant pass arguements cuz flet sucks so i pretty much have to communicate any and all data through globals

[somber hemlock]

You can use lambdas as callbacks

These lambdas can accept any number of arguments and / or even ignore originally passed "event" argument

Like

ft.Button(..., on_click = lambda e: myclickhandler(e, f, g))

[lucid cedar]

👀 that's smart no one told me about this
btw if u know what's the e thing that's always passed on button clicks?

[somber hemlock]

Idk if its really like that, but if it is the "e" contains the click event information - stuff like at which coords mouse click happened etc.

I have no idea so you should look the on_click in docs

[lucid cedar]

i seeee i thought it just passed the whole page or some thing so i could avoid nested functions but looks like am out of look lol

[somber hemlock]

The correct way to use references to parents in flet is to assign them to variables first and then append their children

Instead of

ft.Column(ft.Row(ft.Button(...)))

use

col = ft.Column(...)
row = ft.Row(...)
btn = ft.Button(...)
row.append(btn)
col.apppend(row)

[lucid cedar]

i usually just have the children in it while assigning it to the variable 💀 my current code is full of bad practices lemme get this one working, and then i will work on optimisation while following good practices

[somber hemlock]

only whenever required

[somber hemlock]

yea nesting would have worked awesome if flet provided an alternate way to reference controls, like for example by name, so then this name can be used anywhere inside children to reference any parent

[lucid cedar]

that's where walrus operator shines ✨ ||if i understood what you meant correctly||

[somber hemlock]

Yes but such code looks trashy

[lucid cedar]

💀 idk but walrus operator looks cool to me

[somber hemlock]

walrus operator for all good it does reduces readability which can be a big issue when combined with the way black formats parantheses and like 10 level deep nesting

[lucid cedar]

that's true, btw do you know about any good formatter in vs code... autopep8 isnt really helping with all these bad practices and unneccessary nesting

[somber hemlock]

The correct (and often most efficient) way with frameworks like flet is to make small reusable components, you should try doing that whenever you see duplication and certain repeating patterns

[somber hemlock]

At this point its black or nothing, unfortunately. I do have certain conflicts with the decisions it takes, but I can easily turn it off for a few lines of code or a block

[lucid cedar]

yea i took care of that but it's all nested function so i probably will have to work on it

[somber hemlock]

If your components are reusable then for every component, the function that creates and returns it should be in the module scope

[lucid cedar]

naw but i didnt think of the lambda approach so i couldnt pass page outside the function as easily and it would all just end up being a headache

[lucid cedar]

does the formatter affect syntax highlighting?

guess i will have to switch back to something else cuz it aint colouring the module name and class name and stuff

[somber hemlock]

Syntax highlighting is an IDE concern, black has no way or need to get it

[somber hemlock]

seems something else

[lucid cedar]

then it must be my stupid lap not loading the stuff 💀

[somber hemlock]

yea use pylance preview if vscode

Preview version > stable

[lucid cedar]

i have pylance idk it happens quiet a lot to me though whenever i open vscode it takes like 10 mins to complete syntax highlighting

[somber hemlock]

yea use preview

should fix that

And make sure it isn't accidentally scanning your entire venv by any chance

[lucid cedar]

lemme try tho i thought it was cause my ram usage remains so high

[somber hemlock]

btw have you enabled any of the linters from python extension?

[lucid cedar]

um what are those

[somber hemlock]

Like flake8 or mypy?

pycodestyle, pydocstyle and the worst registered offender pylint?

Check if you have, disable those, they slow everything down

[lucid cedar]

nope pylance, python, autopep8 and black are the only extensions i downloaded

[somber hemlock]

These stuffs are enabled from inside the python extension

[lucid cedar]

i dont think i have any

[digital rose]

i've accidentally created a shield.

[floral marsh]

Hi, did anyone of you installed python and electron on windows? Which environment do you suggest? visual studio? Is it true, it’s a bit a nightmare to compile an electron project on win?

[floral marsh]

(Or, is there a tool you suggest for cross platform gui?)

[humble tundra]

Electron uses javascript its not a nightmare to use

You can easily make desktop apps with it

And easily build for win, Mac, linux

[humble tundra]

Personally I will suggest Tauri it uses rust as a backend and js on the front-end

Electron is well a mem hog and takes a lot of mem so I will suggest Tauri it uses wayy less mem than Electron

[lucid cedar]

ah yea it took quiet long but i figured it out, it was quiet easy with the help of oop i was just being dumb back then

thank u so much for the help otherwise there was no chance i could think of this

sorry for the random ping

[digital rose]

Hi all. Can you please tell me how to fix the background of the button so that it is green? When you run the code, the background of the button is gray and only the borders are green.

from tkinter import *
from tkinter import ttk
 
root = Tk()
 
b_tk = Button(text="Hello Tk")
b_ttk = ttk.Button(text="Hello Ttk")
 
b_tk.config(background="#b00",
            foreground="#fff")
 
style = ttk.Style()
style.configure("TButton",
                background="#0b0",
                foreground="#fff")
 
b_tk.pack(padx=10, pady=10)
b_ttk.pack(padx=10, pady=10)
root.mainloop()

[elfin stirrup]

@digital rose you don't seem to have made your button use the style you created

[digital rose]

His button style is green. And in the end, only the borders are green. If you remove the style, the green borders will disappear. Tell me, please, why is there a gray area inside the button?

[elfin stirrup]

@digital rose it's actually working fine on my device

I haven't installed a screenshot functionality yet, but it's displaying green background color, and when I hover over it, the color changes into grey

[digital rose]

😕 Eh. Thank you

[turbid ravine]

guys, im doing a CLI suggestion kinda tool, for click CLI apps
i've made some changes to the bottom bar, but idk which one to choose
i just need some suggestions and some UX review on which one to choose
but here are the differences that i see between both of these

1. the first one is just indicating the number of arguments that a parameter can get, so that less number of function calls are happened to update the bottom bar, compared to the latter one

2. this one btw, updates more frequently to indicate the number of arguments that a parameter can accept, and indicate the remaining number of arguments it needs

this is the click code (group, and the subcommand shown in the video)

@click.group(invoke_without_command=True)
@click.pass_context
def cmd_group(ctx):
  print('lvl1')

@cmd_group.command()
@click.argument("val", type=click.BOOL, nargs=4)
@click.option("--val1", type=click.BOOL, help="Some boolean optional arg")
@click.pass_context
def bool_type_arg(ctx: 'click_repl.ReplContext', val, val1):
    print(ctx, val, type(val), val1)

@cmd_group.command()
@click.pass_context
def repl(ctx): # this is the command that im calling from the command line
    click_repl.repl(ctx)

cmd_group()

so, which one should i choose to use?
(just ignore the bandicam watermark pls, also ping me on reply, i don't want to miss ur answers)

[lucid cedar]

can someone give me the most basic example of a FilePicker in flet

[somber hemlock]

The one in docs isn't?

[lucid cedar]

i dont really know how to get the path

[somber hemlock]

https://flet.dev/docs/controls/filepicker#result

FilePickerResultEvent contains a path attribute, so its just e.path in your callback

[lucid cedar]

i see, like in the example there was only e.name, so i didnt realise, thanks

Hi there,
I am converting a simple Tic Tac Toe program that works in the terminal, to a popup GUI window.

However I am struggling with "print" commands.
I want to print the gameboard on a Popup GUI window (NOT the simple debug window that GUI provides)

This is my code.

    for x in range(rows):
        print("\n+---+---+---+")
        print("|", end= "")
        for y in range(collumns):
            print("", gameboard[x][y], end= " |")
    print("\n+---+---+---+")

sg.theme('DarkTeal9')

layout =[
    [sg.Text("Please fill")],
    [sg.Text(printGameBoard(), size=(15,11))],
    [sg.Submit(), sg.Exit()]
    ]

window = sg.Window("Tic Tac Toe", layout)
while True:
    event, values = window.read()
    if event == sg.WIN_CLOSED or event == "Exit":
        break
    if event == "Submit":
        break
window.close()```

The gameboard prints like this..

+---+---+---+
| 1 | 2 | 3 |
+---+---+---+
| 4 | 5 | 6 |
+---+---+---+
| 7 | 8 | 9 |
+---+---+---+

*btw thats just the important bits of code, there is more that i havnt included lol

[fair locust]

Is it possible to share open source project here without being banned? Or is it like advertising

[fair locust]

Is there some efficient front end framework for python according to you or is always better to use JavaScript for your python front?

[somber hemlock]

how do you define efficient?

[fair locust]

I think but I may be wrong that most frontend python frameworks are more for prototyping than for production

[somber hemlock]

PyQt / PySide is solid for production and used by many real world apps

[fair locust]

I will have a look at that thanks. Is it generic or for data visualization?

[somber hemlock]

There are tons of very easy to use libs for data visualisation. PyQt is a generic UI framework

[drifting spire]

i prefer the second, with succinct description for optional like optional: bool or something

[turbid ravine]

there cant be no optional bool
it can only use types from the click module

[exotic socket]

Looks cool 😎

Struggling to see the difference between 1. and 2. though

[turbid ravine]

the difference is in the bottom bar

did u notice it?

[exotic socket]

Still can’t see it, and watched both videos 5x

[turbid ravine]

what?

u didnt see the text like bool-type-arg flashing at the last line of the terminal?

@somber hemlock , I'm following up on some of your advice recently on this channel about Qt. What are the advantages and disadvantages to developing with Qt versus BeeWare?

[solid wedge]

Hello folks, I have been learning tkinter for GUI. I am a super beginner, as such I'm trying to make sure I don't invest a bunch of time learning a GUI that is going away in the next few years. I thought I had read that tkinter was being discontinued but now im not finding that.

is there a better GUI to be learning not just for this script but for long term support as I continue to learn?

[sleek hollow]

pyqt/pyside would be the better alternative if you want something more professional and powerful

[solid wedge]

Thanks, I'll give that a look. This is tangential to my regular work but I want the foundation to be solid moving forward. Learning something that will be around still is important

[sleek hollow]

This is the first I've heard that tkinter support is going away, but even still, it's a fairly simple UI and really shouldn't be used for anything that needs more complexity

[solid wedge]

To be clear - I had read that somewhere a while back and can't find it again. I had already spent some time learning the GUI elements but didn't want to commit to something that might be going away. No idea if it's actually going away or not.

[digital rose]

[brazen nacelle]

Hello!
I am building Menu for my Draught in Python, pygame.
I've built class 'OptionsScreen', which stores all the TextBox, Buttons etc. and draws them.
When it comes to give some functionalities to Buttons, what is the best practice:

1. Button have an attribute (of type function), where I can store the function I want to process after clicking on the button. Something like this:

button_do_smth.function_to_process = self.do_smth
button_clicked = button_do_smth
button_clicked.process()

2. Class managing the screen and all the elements (i.e. 'OptionsScreen' in my case) should process all events in a way like this:

if button_clicked == button_do_smth:
    self.do_smth()

Hi, I am writing code in Eel to avoid possible complications of Electron. Maybe is Eel too simple? As I see on Github comments, you can’t communicate between python and jinja (and probably with any other template)

[lucid cedar]

i think this part is the problem

def render_shop(page):
    shop = flet.GridView(runs_count=4, expand=True)
    products = requests.get(url + "/get-names").json() # returns a 20 element long list of strings
    for name in products:
        PopulateShopGrid(shop, name)
    page.add(shop)

class PopulateShopGrid:
    def __init__(self, grid, name):
        self.name = name
        img_link = (requests.get(url + f"\get-url?query={self.name}").json().values())[0]
        price = (requests.get(url + f"\get-price?query={self.name}").json().values())[0]
        item = flet.Column(
            [
                flet.Image(
                    src=img_link,
                    width=200,
                    height=200,
                ),
                flet.Row(
                    [
                        flet.Text(name.capitalize(), size=20),
                        flet.Column(
                            [
                                flet.Text("price"),
                                flet.Text(str(price)),
                            ]
                        ),
                    ],
                    alignment="CENTER",
                ),
                flet.TextButton("View", on_click=lambda e: self.scrape()),
            ],
            horizontal_alignment="CENTER",
        )
        grid.controls.append(flet.Card(content= item))

[somber hemlock]

what is self.scrape?

Btw you don't need a class at all here

[lucid cedar]

    def scrape(self):
        scrape(self.name)

where scrape just clears up the screen and adds the name and an image to an screen, however scrape is likely not the issue, since once i press the button calling scrape, the memory usage decreases back to normal.

[lucid cedar]

ah i do, cuz there is no way to make the button call pass dynamic arguements to another function otherwise

[somber hemlock]

have you looked into nested functions? also what is "dynamic arguments"?

[digital rose]

what are these widgets/objects called that allow you to decrease/increase value?

[timber yacht]

Html ?

If yes, then it's an input with type="number"

[digital rose]

ah it's called spin box, someone in #python-discussion told me

[digital rose]

i know it's a number input lol, the up and down arrow part is the big deal for me

[timber yacht]

Oh you want the exact name

Nvm

[digital rose]

it's alright

also spin box is garbage name since we don't see the numbers roll up or down lel

could've used an updated name tbh

[floral marsh]

https://github.com/python-eel/Eel/issues/217

[lucid cedar]

i dont have any nested functions, cuz i just followed an oop based approach

and by dynamic arguements i mean, that they are different for each one, and keep changing

[elder hinge]

does anyone know how can i overlay an image over a tkinter progressbar?

I've managed to workaround all the quirks that tkinter has besides this one

[magic ether]

Im using pyside6 and im trying to have an image maintain its aspect ratio when the window is resized but the image gets distorted whenever i resize my window. I have tried with smooth transformation and all kinds of sizepolicy stuff and no solution has worked for me. ```python
class ScaledLabel(QLabel):
def init(self):
super().init()
#self.setScaledContents(True)

def resizeEvent(self, event):
    pixmap = self.pixmap().scaled(event.size(), Qt.AspectRatioMode.KeepAspectRatio)
    self.setPixmap(pixmap)

class MainWindow(QMainWindow):
def init(self):
super().init()

    label = ScaledLabel()
    label.setPixmap(QPixmap("qtforpython.png"))
    self.setCentralWidget(label)

this is what it looks like distorted (the img is the python for qt wiki logo)

[solid jackal]

Im not entirely sure if this is the right spot for this, but I had a passion project moment and built a Terminal UI library that im pretty proud of.

It supports buttons, clicks, hover effects, textboxes, and more (all in a modern terminal) and is very customizable to the developers liking. It is in no way a replacement for tkinter or pyautogui but I'm sure someone will think it is as cool as I think it is.

Hi guys.

I'm trying to run a ui file through a python file, but it doesn't work (the ui file doesn't launch from this py file)

from PyQt5 import QtCore, QtGui, QtWidgets, uic

class Application(object):
    def __init__(self,app):
        self.app = app
        self.ui = uic.loadUi('untitled.ui')

        self.ui.show()
        self.run()
    def run(self):
        self.app.exec_()

if __name__ == '__main__':
    import sys
    app = QtWidgets.QApplication(sys.argv)```

the ui file is in the same folder as the py file btw

[sleek hollow]

I believe you need to inherit from QMainWindow for your class

[digital rose]

ah how do i do that?

can you shw example

[sleek hollow]

class Application(QtWidgets.QMainWindow)

[jagged hill]

Hello! I have created this form inside a GridLayout. I added spacers to center the contents in the window. How can I center the submit button inside the cell in which the submit button is contained in?

[digital rose]

i did that but still didn't work

[sleek hollow]

You're not creating an instance

[sleek hollow]

You can set a columnspan when adding a widget to a grid. What layout does the form use?

[somber hemlock]

why do you need to subclass QApplication for just that much?

also top level imports please

[digital rose]

ah actually i figured out how to do it by now

I do have another problem atm though

I'm trying to interact with my ui file's widgets via the python file, but it only seems to work for the first time the function "chucked" is called

class UI(QMainWindow):
    def __init__(self):
        super(UI, self).__init__()
        uic.loadUi("untitled.ui", self)

        self.coordYb = self.findChild(QSpinBox, 'Ybig')
        self.customize = self.findChild(QCheckBox, 'customize')

        self.customize.clicked.connect(self.chucked)
        self.show()
    def chucked(self):
        if self.customize.isEnabled() == True:
            self.coordYb.setEnabled(True)
        elif self.customize.isEnabled() == False:
            self.coordYb.setEnabled(False)```

when i click the self.customize checkbox, the spin box, becomes enabled, but then when i click the checkbox again, to uncheck, the spin box doesn't become disabled

nvm, i was supposed to write self.customize.isChecked()

not isenabled

now it works

[digital rose]

does anyone know an alternative to "clicked" for qcombobox?
map is a combo box widget and i tried this self.map.clicked.connect(self.mapInfo) and got this

[digital rose]

fixed it

[grand zenith]

Does anyone know why window.move in Qt doesn't work? I'm using PySide2 5.15.8 and I'm on Ubuntu Wayland. Is this a known bug in Qt?

Does anyone know a C or Python library that allows you to move the window based on its handle or PID?

[wet vapor]

i have a problem donwloading tdesigner does anyone know how i can fix this

[misty canopy]

pygetwindow seems to have that feature: https://pygetwindow.readthedocs.io/en/latest/

[somber hemlock]

Whether it is really possible highly depends on your window manager. Wayland doesn't support moving of window programmatically. DWM (Binbows) supports this.

@warped shuttle what module are you using

[clever trout]

I used to use regular tkinter, but then I decided to try custom tkinter, but there was no list box, so I downloaded the CTkListBox library, and now the code doesn't work because I don't know how it works

pls help me

[sleek hollow]

You can set it to the application's styleSheet

from PyQt5 import QtCore, QtWidgets, QtGui
from PyQt5.QtCore import Qt


class Window(QtWidgets.QMainWindow):

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

        self.main_widget = QtWidgets.QWidget()
        self.main_layout = QtWidgets.QVBoxLayout()
        self.main_widget.setLayout(self.main_layout)
        self.setCentralWidget(self.main_widget)

        self.main_layout.addWidget(QtWidgets.QLabel("Hello World"))
        self.main_layout.addWidget(QtWidgets.QPushButton("A button"))
        list_wdg = QtWidgets.QListWidget()
        list_wdg.addItems(['apples', 'oranges', 'bananas'])
        self.main_layout.addWidget(list_wdg)
        

app = QtWidgets.QApplication([])
with open('style.txt') as f:
    app.setStyleSheet(f.read())
win = Window()
win.show()
app.exec()

save that stylesheet to a textfile and read it in. Then you can use setStyleSheet to set the style to the app

[hexed horizon]

anybody know how to center a tkinter window

    newWindLab = tk.Label(newApp, text=(bPressed), font=('Times', 50)
    newWindLab.pack()
newWind('Placeholder 1')

when I run it, the window created is about ten pixels offset on the x-axis

but the bg has to be black

[proud dune]

There is currently a black box on the top part of the app

[narrow hedge]

but, I want the whole app to be black

including the bottom section, where the icons are present

[proud dune]

Add gui.configure(bg='black') after gui.geometry

[narrow hedge]

well, that kinda did it, but...

[proud dune]

To change the background color of a ListBox, use songList.configure(background='black', foreground='white')

[narrow hedge]

wait, isnt it fg and bg?

[proud dune]

It's background and foreground (That works on my environment)

[narrow hedge]

oh, that didnt change it man

[narrow hedge]

It's still like this

[proud dune]

Is the songList listbox element empty?

Try adding some content in it so we can see it's width and height

[narrow hedge]

nope, I this is the songlist songList = Listbox(root, background='black', foreground='white', width=100, height=15)

[proud dune]

Try adding songList.insert(1, "Test Value") after that line (songList = Listbox(...))

[narrow hedge]

wait a min, when I gave the height as 15,

[proud dune]

That top black box was the listbox, then.

[narrow hedge]

bro

[narrow hedge]

yeah

[proud dune]

Wait, are the button images transparent? Do they have white backgrounds?

[sleek hollow]

Your listbox is empty, that's why you aren't seeing anything

[narrow hedge]

Yeah, there is actually a next icon too, but that one is white so you cant see it on the white part

but can I actually bring the listbox down?

Im actually using transparent icons too

[proud dune]

Oh, alright

To place the listbox below the buttons, you could declare it (using the ListBox class) after them.

@narrow hedge It seems you are AFK, let me know when you're back!

[sleek hollow]

The order you pack things is the order they show up

[proud dune]

That is correct

[sleek hollow]

It's not the order you instantiate the class as you mentioned above

[narrow hedge]

hey, man. @proud dune Sorry for going AFK on you...(I was busy helping mom, XD)

Alr, so I gotta change the order

yeah?

[narrow hedge]

oh yeah, that actually worked

but, what actually want is to make the bg of the controlframe part to be black

and bring all the icons inside that

[sleek hollow]

well you didn't set the bg colour of that frame

controlFrame = Frame(root)

controlFrame = Frame(root, bg='black')

[narrow hedge]

oh yeah, mate, silly me

thanks, that actually did it

I dunno why, but I actually forgot that for a moment

[thick lichen]

Hey everyone
Just a quick on for you.

I get this error when trying to import my menu_bar.py file:

I have an image below displaying the code I have but If I change the import statement to either of the following it works:

# Relative Import
from . import menu_bar

# Alternate Import
from GUI import menu_bar

[next ridge]

when executing main_window.py directly, import menu_bar will work since the module is adjacent to the main file.
tho not sure which module you're running as the main script

[thick lichen]

Hi there,
I have a main.py sitting at the src level

[next ridge]

Well then you can't import menu_bar directly as it isn't visible from main

manu_bar is inside the GUI package

so you must use from GUI import main_bar, when main.py is the main script

[thick lichen]

Yea this is what I had but Pycharm complains 🙄 Just wanted to make sure I was not miss understanding something 🤔

[thick lichen]

Thank you for your Assistance 🙂

[winged mesa]

Hello i have question, How to get value of checkbox from FLET module?

[next ridge]

maybe it has issues with namespace packages?
I've never used pycharm, so can't tell.
namespace packages are folders with py files and no __init__.py

[thick lichen]

Yea My thought exactly.
Even if I add an __init__.py it still gives me an issue 🤣 But it runs... so I will just press on 😁

[coral rover]

Anyone a pro in Plotly Dash?

I wanted to know:
1 - is it true that all callbacks get called automatically at the start, when the app is booted? If so, then in what order? Can that be checked/changed somehow?
2 - does that mean that there's no point in setting the value of a parameter/property inside the layout definition, if that parameter/property is the output of a callback, because it'll immediately be replaced by the output of the first automatic callback call?

[narrow hedge]

hey guys, IM back again

guys, for this progressbar, do I have to use any other library?

to make this exact progressbar

and also to achieve that font

[narrow hedge]

This is just a figma ui that I made, Im trying to make an app in python

[narrow hedge]

also Is this achievable? In python?

[sleek hollow]

Yes you could do this in python. You'd likely need to make your own custom widget for it though

[narrow hedge]

oh

Arent there any pre made widgets for this?

Or like any way to use a stylizing language, like css

[sleek hollow]

Yes, but nothing that looks exactly like this. A slider would be your closest option

[narrow hedge]

ah, yes a slider

So, Ill have to program it, prolly

[sleek hollow]

most things require programming, yes

[narrow hedge]

Guess Ill have to figure that out now, `

[sleek hollow]

Here's an example with pyqt

from PyQt5 import QtWidgets, QtCore

slider_style = """
QSlider::groove:horizontal { 
    background-color: black;
    border: 0px solid #424242; 
    height: 10px; 
    border-radius: 4px;
}

QSlider::handle:horizontal { 
    background-color: red; 
    border: 2px solid red; 
    width: 16px; 
    height: 20px; 
    line-height: 20px; 
    margin-top: -5px; 
    margin-bottom: -5px; 
    border-radius: 10px; 
}
"""

app = QtWidgets.QApplication([])
win = QtWidgets.QDialog()
layout = QtWidgets.QHBoxLayout(win)
slider = QtWidgets.QSlider(QtCore.Qt.Horizontal)
slider.setStyleSheet(slider_style)
layout.addWidget(slider)
win.show()
app.exec()

[tribal path]

Any library where you can draw straight on the canvas would let you imitate that, sliders and progress bars would be the more simpler widgets to write custom instructions for

[frigid cave]

Is there any better ide which doesn't take lot of space and can be run smoothly on a laptop..I mean pycharm lags so much in my laptop..any ideas how to code effectively on command prompt
..or anything ide related

[sleek hollow]

This channel is for GUI library discussion. You can ask about IDE in #editors-ides

[waxen halo]

is the "only" difference between PyQt and PySide the licensing part?
Im a beginner and cant decide which one I wanna use 😄

[sleek hollow]

There's other minor differences in the library, but for 99% of it, they're the same

[somber hemlock]

PySide exposes a (optional) more Pythonic API. Its just lower_case names and properties instead of getter setters atm.

[waxen halo]

What would be easier for a beginner?
And can I use Qt Designer / Creator for both?

[somber hemlock]

Both are the same. PySide code can be made to look slightly more Pythonic is all. You can use Qt Creator or designer for both

[rocky dragon]

in the end they're both wrapping Qt as closely as possible, though getting support / stuff fixed for pyside seems easier as last time I looked I could only find mailing lists for pyqt

[royal atlas]

Would this be the right channel to ask for help with a cli tool?

[blazing pine]

having a head scratcher of a Qt Widget sizing question, I have a tree view, but annoyingly it shows up w/ a horizontal scroll bar, is there a way I can have the width of the widget fit all the contents?

Screenshot:

some things I'm calling...

trreeView.header().setSectionResizeModel(QtWidgets.QHeaderView.ResizeMode.ResizeToContents)
treeView.header().setCascadingSectionResizes(True)

horizontalSizePolicy = QtWidgets.QSizePolicy()
horizontalSizePolicy.setHorizontalPolicy(QtWidgets.QSizePolicy.Policy.Expanding)
treeView.setSizePolicy(horizontalSizePolicy)
treeView.setHeaderHidden(False)  # yet I cannot see the header still, what gives?

treeView.setModel(myModel)
treeView.header().setStretchLastSection(False)
treeView.setItemDelegateForColumn(0, MyCustomDelegate())
treeView.expandAll()
treeView.updateGeometries()
for column in range(2):
    treeView.resizeColumnToContents(column)
treeView.setAlternatingRowColors(True)
treeView.show()

I think that should be everything relevant...

well, this is embarassing, i commented out a ton of that stuff, and it looks ok now?

[twilit whale]

could it also be having horizontalsidepolicy.sethorizontalpolicy(etc) vs horizontalsizepolicy?

[blazing pine]

oh whoops, that's a typo on my end when migrating my code to discord here, my mistake 🙏

[twilit whale]

no worries! im pretty new to everything but thought it could be that haha

[blazing pine]

haha pycharm would yell at a lot and my code would blow up when I ran it if that was actually the case

[blazing pine]

ok found a post from 10 years ago detailing what I would have to do to get the bahvior I want as described here: https://www.qtcentre.org/threads/53948-resize-to-content-of-a-QTreeWidget

If you really want to resize tree view based on its content then you will need to code to calculate the "correct" size and force it. Set all the sections to QHeaderView::ResizeToContents and query them for their size after every data update to get a reasonable starting point. No matter how much sense it makes you eventually hit the point where the content is too wide for the screen and you are back to where you started.

so, after reading that, yeah, I probably don't want to do that, and instead should just disable word wrap and truncate the text...

[somber hemlock]

what's the problem with scrollbars? they are inevitable

you can make them appear only when content overflows (default behaviour probably)

[blazing pine]

issue is that I have my tree-view populated before calling .show(), so was hoping to have the initial display of the TreeView conform to size such that no scroll bars would be necessary, but after reading that comment, I think that's just a losing game, best to implement single line/no text wrap with elided text

in my case i'm using a QStyleItemDelegate (not too experienced with those!) so I have some extensive control over the content being displayed in each cell...

now, I need to try and think of a cleaner way to update the cells via dataChanged.emit(QModelIndex, QModelIndex) ...the cells have Progress Bar's embedded, and figuring out how to notify the cell view to update because the progress bar has updated is remarkably not trivial (right now if any progress changes, I update the entire tree view which for my size works fine)

[somber hemlock]

Everything centred around Qt's QAbstractItemModel is a PITA to work with. I realised that its just better to not use a tree if you can (and instead use a grid layout?) However that too is inefficient for a large number of rows

Gtk4 has a much much better designed API to create and populate list / column / tree views.

[somber hemlock]

I think you should be able to handle this with QStyledItemDelegate signal/slots

[blazing pine]

I’m already using the QStyledItemDelegate, definitely need to use signals/slots, would likely need to make sure that the connection is a unique connection but I know how to do that…

zsh: segmentation fault (core dumped)  qtcreator

It was working fine a few days ago, any idea?
Qt Creator 11.0.1 based on Qt 6.5.2

This happens when modifying any widget in the design page

[next ridge]

Hmm ok, so this seems to happen only in wayland and not xwayland

[blazing pine]

Oh if running wayland, you may need to set some environment variable; I’ve had not great luck with wayland when working with PyQtGraph

[somber hemlock]

You could make a custom signal and pass in an object ref through it

[somber hemlock]

File a bug report on the Qt issue tracker

[next ridge]

It started crashing only after some system update

not sure if qt creator was updated too, I didn't pay attention

[somber hemlock]

heh unix ppl problems

[next ridge]

this?
https://bugreports.qt.io/projects/QTCREATORBUG/issues

[next ridge]

more like qt's problem

[somber hemlock]

yup

[somber hemlock]

wayland is still somewhat of an experimental WM itself

it doesn't allow window positioning

[blazing pine]

https://doc.qt.io/qt-6/wayland-and-qt.html#what-qt-wayland-offers

try running QtCreator with -platform wayland ?

[next ridge]

Idk, I only get issues with qt on wayland

gtk has been perfectly fine

even dialogs are opened centered

[next ridge]

crashes just like before, that's probably the default option on wayland system

[somber hemlock]

Gtk4 underwent a lot of rewrite and change to support Wayland. Now it doesn't support X

Gtk3 idk, won't be so good on Wayland

[next ridge]

@blazing pine for now, I'll just run it with QT_QPA_PLATFORM="xcb"
Will make a report tomorrow

[next ridge]

This is case sensitive for me

QFileDialog.getOpenFileName(self, filter="JPEG (*.jpeg)")

How can I make it not so?

[somber hemlock]

You mean you want .JPEG also?

[next ridge]

ye, windows treat file association by extension insensitively

that's why i want similar behavior

[somber hemlock]

You can use this filter

"JPEG (*.jpeg, *.JPEG, *.jpg, *.JPG)"

[next ridge]

will it work for *.JpEg?

[somber hemlock]

No

[next ridge]

https://cdn.discordapp.com/emojis/1105114544533160036.webp?size=48

[somber hemlock]

Even the Windows OS API (which is what Qt uses internally) doesn't allow for case insensitive filters

[somber hemlock]

If you got files named like that, there's high chance somebody is trying to mess with you

[next ridge]

https://cdn.discordapp.com/emojis/1104749384090013696.webp?size=48

[somber hemlock]

Crash your application when you detect such file names

Don't even bother calling some nice clean exit function like sys.exit. just do os.abort or something

[waxen halo]

is there an easy way to implement a QFileDialog into PySide6? I cant find anything in Qt Creator

[royal gull]

Looks like the docs has you covered.

fileName, selectedFilter = QtWidgets.QFileDialog.getOpenFileName(self,
    "Open Image", filter="Image Files (*.png *.jpg *.bmp)")

(excerpt from the docs; modified for clarity)

It's the sort of stuff you have to do in code though.

[waxen halo]

hmm okay, was hoping there is an way easier way 😄

[royal gull]

Yeah, the way it's usually done with Qt Creator/Designer is that you make the UI, export it as a .ui file, then run pyuic on it and import the generated Python code into your app (you could also use PySide6.uic to import the .ui file directly). That way, you can add handlers for the widgets or additional code as needed.

I'd recommend you get comfortable with at least the basics of the code. Qt can be complicated but it's probably the most powerful GUI for Python out there.

[waxen halo]

Yea I think I’m gonna skip the QFileDialog for now and get my app running, after that I can still change some things

[graceful gate]

can someone recommend me some easy and scalable modules to make user-interfaces?

like able to use dbs and stuff with it

[hexed horizon]

commonly used ones are PyQt5, Tkinter (if you use this one, also learn customtkinter and/or ttk), and PySimpleGUI. i would recommend using customtkinter for a modern style, but choose what works best for you

[somber hemlock]

You can do this with QML

Declare the FileDialog in your qml and use it there itself

[sleek hollow]

Your main Tk instance shoud always be global. Otherwise you're just creating multiple instances of your tkinter application and the windows can't talk to each other

hi i need some help

for some reason on tk they don't show rounded edges on my gui whereas it does on figma (im creating a gui)

[serene badge]

[somber hemlock]

rounded main window corners or widget corners?

[dire barn]

Having read the sticky, I am still unsure what framework to use. I want to write a relatively simple GUI:

• macOS is the only platform I care about
• I want native widgets
• I want to display a PDF in a widget, everything else is probably boring standard components.

Toga looks promising, but a bit unfinished.. I'm not sure how I would display a PDF there. With what framework would I have the least amount of pain?

[somber hemlock]

pywebview to render the pdf in an OS supplied webview runtime

If you need additional widgets you can wrap the webview in a tkinter window

[sleek hollow]

What do you mean by native widgets? There's QPdfView in pyqt6

[somber hemlock]

QPdfView doesn't use any native components and has a huge dependency and is an entire impl by itself

[dire barn]

Cocoa widgets, not something rendered by some framework. It should look and feel like any other native app.

[somber hemlock]

Pywebview uses cocoa on macos

[dire barn]

Yeah, as long as I only use that for the PDF viewing part..

[somber hemlock]

As a window renderer

[sleek hollow]

is cocoa the current macos? I know very little about mac, haha

I don't think cocoa can render pdfs (is one hell of a job to be pulled of by a gui lib)

But every os has a webview runtime now (mostly preinstalled, you should check)

And the webview can definitely render pdfs

[dire barn]

Yes, it's the successor to Carbon, IIRC. But I also don't know a lot about Mac internals.

[swift cove]

youre saying i should create just one window? not window1 and window4?

[sleek hollow]

Tk() is more than just a window. It's the application instance. If you want more than one window, any additional windows have to be a Toplevel()

[somber hemlock]

multiwindow is just an outdated concept tbh

[sleek hollow]

How so?

[somber hemlock]

you don't find it in newer apps, especially electron ones

[sleek hollow]

I think it entirely depends on what you're building

most VFX software thrive on multi window

[somber hemlock]

and newer ui libs generally implement navigation with pages and routers

[somber hemlock]

maybe because they have a lot of old code / use traditional ui libs?

[sleek hollow]

partially yes, but also because it can be important to see a lot of information at any given time

Floating windows with multiple monitors offers a ton of flexibility

[somber hemlock]

If the windows are dockable as well as floating then all well but if they are just floating it looks super crappy imo

[sleek hollow]

yeah they're all dockable too. You can configure and save any layout, or tear off windows and place them wherever you want

[somber hemlock]

naijce

it seems that modern ui libs aren't matured enough to create complicated UIs yet

like you can't even implement a lazy listview in JS in a half decent manner

Its that bad

Result you end up with pagination

Hey, I developed a web interface using Django for an RFID based attendance system using some microcontroller(ESP8266).
I wanted to check if the http GET request is returning the correct response. Is there a way to find this without actually integrating it in the microcontroller.

In short is there a way of checking the response of HTTP GET requests ?

You mean Tkinter? My local Python doesn't have Tkinter support, and the experiment I tried on my other machine with it was.. ugly, at least the divider wasn't native.

[mighty frigate]

@dire barn why no Qt ?

[dire barn]

I thought Qt drew its own widgets?

[mighty frigate]

possibly and ?

there's a problem with that ?

[dire barn]

See above:

I want native widgets

When not using native widgets, it doesn't feel right, the controls never behave completely correctly.

[mighty frigate]

ok

[long forum]

Currently using TK as a UI and wanting to switch to PyQT. Are there other UI designers similar to QT designer out there that are perhaps better tools?

Can I introduce css into tk to spice it up?

For reference my tk is written directly into a gui module by going qt I'd like to introduce UI files and keep my gui module just for initialization and functionality.

[floral igloo]

qt creator

although I prefer qt designer and a model view structure, the ui file is seperate and generated by qt designer

https://github.com/yenaras/renamer.git

[mighty frigate]

for what it is worth, it might be usefull to look into QtQuick (qml) right away. As far as I can tell, less and less companies are using QtWidgets.

[next ridge]

do we have to write qml by hand?

[queen trout]

Got it working

[mighty frigate]

there's a designer, like QtWidgets afaik

tbh I prefer not using designers and write everything myself so I don't know much about that

[lunar portal]

i was coding a gui using tkinter for my project and when i run the code and give something in the entry fields and click enter it is not going to the next line can someone help me

[next ridge]

Is Entry in tkinter a multiline text widget?

[lunar portal]

no

[next ridge]

well then there you go, problem solved

[sleek hollow]

use Text if you want multiline

Or multiple entries. Depends really on your goal

do you want it so if you press enter in the username entry it moves to the password entry?

[lunar portal]

yea like that

i figured it out

[next ridge]

ah u just want to switch focus

[lunar portal]

had to focus next

[somber hemlock]

Writing QML by hand is better than using the Qt Widgets designer.

You can use Qt Design Studio as a Qt Designer replacement for QML, although you still will have to manually write some QML yourself

[next ridge]

btw, can I add custom widgets written in python to at creator's designer?

[somber hemlock]

Yes

[next ridge]

ye i looked at qml, much better than XML garbage

[somber hemlock]

That is entirely possible

[next ridge]

nice, i was starting to feel qt creator is too limiting

[somber hemlock]

its focus is on readability

and its super easy to create bindings

Not so easy in Qt Widgets

[next ridge]

I already did my app using .ui forms

I'll use qml if I do some other project in qt

[somber hemlock]

Qt Widgets really exposes only like half of the XML capability of UI files

[somber hemlock]

You can use QML and Qt Widgets both in a single app

By using QQuickWidget for QMl stuff in your widgets application

[next ridge]

Ok

How to add context menu to a QTableView to copy a field value from selected rows? I got selectionBehavior set to SelectRows so can't select individual cells to copy

Should I assign a new function to contextMenuEvent method with QMenu stuff?

[next ridge]

Could you send the link to the file containing this auto completer?

[quasi oxide]

I'm building a tkinter app. My main window has multiple frames attached to the first grid row, which I switch between using tkraise()
However I am not able to get the elements inside frames to center.
I have tried row and column configure but to no avail
The code in question: https://github.com/DeathVenom54/voting-ip-project/blob/cd412d86e1a6773fa65c8474f4073342f8cdbbb7/frontend/App.py#L19C8-L19C8

https://github.com/DeathVenom54/voting-ip-project/blob/pyqt/frontend/opening_page.py

[proven basin]

frontend/App.py line 19

# instantiate all frames```

[quasi oxide]

(please ping when answering)

[hexed horizon]

@quasi oxide the grid parameter reads 0,0 as top left, try different values for the argument or use .place with different param values. For example: ```py
label = tk.Label(frame, text='POLL PILOT')
label.place(relx=0.5, rely=0.5, anchor=CENTER)

[quasi oxide]

Doing column=1 on one element does put it on the right but if I set column=1 for all, they're still on the left

I'd prefer using grid as you can make layouts quite easily with padding as well

Place needs x and y positions

[sleek hollow]

What are you trying to center? Everything in the middle of the window?

[queen trout]

I'll send it to you later

[quasi oxide]

yes

I chenged bg color and found that the frame is in fact not occupying all space in window

        # instantiate all frames
        for (name, frame) in App.frames_data.items():
            self.loaded_frames[name] = frame['frame'](self)
            self.loaded_frames[name].grid(row=0, column=0, sticky='news')```

So the sticky='news' isn't working?

Got it to work! I just had to use rowconfigure and columnconfigure for the App (main Tk window)

[hexed horizon]

@quasi oxide you could do something like this ```py
self.loaded_frames[name] = tk.Label(frame, text='POLL PILOT')
self.loaded_frames[name].place(relx=0.5, rely=0.5, anchor=CENTER)

[quasi oxide]

Thanks, I got it working with grid though

[hexed horizon]

ok cool

[quasi oxide]

self.rowconfigure(0, weight=1)
self.columnconfigure(0, weight=1)

Added these 2 lines to root tk.Tk

[hexed horizon]

yeah that works too

[queen trout]

use the clicked connection

or itemChanged

I dont think ot has a clicked connection

def tracks_list_contextMenuEvent(self, event) -> None:

    copy_menu = self.menu.addMenu("&Copy")

    copy_menu.addAction(album_copy)

    ...
    self.menu.exec()

self.tableView_tracks_list.contextMenuEvent = (

How am I supposed to spawn a menu properly?

It always spawns at the top left corner (even outside the app)

[queen trout]

import Qcursor from QtGui

then use the Qcursor.pos()

I just had this issue like 5 mins ago lol

[next ridge]

            self.menu.exec(QtGui.QCursor.pos())

it worked, thanks

https://cdn.discordapp.com/emojis/1100932026774855700.webp?size=48

[queen trout]

yup np

very cool gui btw

[next ridge]

thanks, tried qt for the first time

[queen trout]

did you use the designer?

[next ridge]

ye

[queen trout]

yeah same

I got my gui made, I just have to fix the full screen and stretching now

which is gonna suck

[next ridge]

I got issues with centering stuff too, I just use spacers and set max width for widgets as a workaround for now

[queen trout]

I dont even have a layout, everything is static lol

so...pain

[next ridge]

ye here, maybe you shouldn't spawn different windows

just use stacked widgets for different pages

That chat app ui is fine as a sepearate window tho

[queen trout]

in my program code I spawn all my windows once, the. I just show them

much easier to code and setup

and it allows me to have a separate file for each page

the main reason I did this is because I couldn't find out how to resize different pages

[next ridge]

Pages in stacked widgets have their own layout

but it's being a mess for me too, settings alignment for one page, sets for all of them, Idk why

[queen trout]

yeah im not sure, I tried resizing one page and it would just change the others

yup

thats why I switched

[next ridge]

You may use this for screencast https://github.com/ShareX/ShareX instead of bandicam lol

[queen trout]

yeah I use OBS now, it's just a pain to setup. Bandicam takes like 5 seconds to fit thr screensize I need

[next ridge]

tho...How do I use some state outside this method?

The text I'll be copying to clipboard is not part of self

can't modify the method params either

[queen trout]

just make a self.text statement

[next ridge]

umm, the text is already there but not part of self

how would I bind it to self if I can't even access it?

[queen trout]

wait what line

[next ridge]

In TableView

    def setModel(self, model: PySide6.QtCore.QAbstractItemModel) -> None: ...

what does this method do?

because the text I want to copy is inside the model

[queen trout]

check the methods with dir

oh wait

are you trying to get the text of the table?

like the selected row?

[next ridge]

ye

[queen trout]

ah 1 moment, let me go through my code

[next ridge]

        # Setup tracks list model
        self.tracks_model = TracksModel()
        self.tableView_tracks_list.setModel(self.tracks_model)

        def tracks_list_contextMenuEvent(self, event) -> None:
            self.menu = QtWidgets.QMenu(self)
            copy_menu = self.menu.addMenu("&Copy")
            copy_album = QtGui.QAction("&Album", self)
            copy_menu.addAction(copy_album)
            copy_title = QtGui.QAction("&Title", self)
            copy_menu.addAction(copy_title)
            copy_artists = QtGui.QAction("A&rtists", self)
            copy_menu.addAction(copy_artists)
            copy_link = QtGui.QAction("&Link", self)
            copy_menu.addAction(copy_link)

            # This contains the text
            # [
            #     self.tracks_model.tracks[row.row()]
            #     for row in self.tableView_tracks_list.selectionModel().selectedRows()
            # ]

            self.menu.exec(QtGui.QCursor.pos())

can't access the model from TableView object

[queen trout]

So I did a connection

self.connect_window.ui.ServerTable.cellClicked.connect(self.cell_clicked)

Then I did this in the cell_clicked

def cell_clicked(self, row, column):
        self.selected_row = row
``` then when I call some other method like load etc. I check and see what the current self.selected_row is

or do you mean you right click on a cell , then the menu shows up

like copy etc

[next ridge]

I can get the rows using

            print(self.selectionModel().selectedRows())

that's not the problem

the problem is that I need to access the model data

[queen trout]

Ah then I have no idea. I've never used a model

why do you need a model in the first place?

All my code info is shared through a class

[next ridge]

i found model in dir(self)

maybe i can access model through that

oh ye, it worked

thankfully

...
def get_selected_tracks():
    return (
        self.model().tracks[row.row()]
        for row in self.selectionModel().selectedRows()
    )

def copy_fields(fields: Iterable[str]) -> None:
    QtWidgets.QApplication.clipboard().setText("\n".join(fields))

copy_album.triggered.connect(
    lambda: copy_fields(
        (track.album_name for track in get_selected_tracks())
    )
)
...

[queen trout]

      menu = QMenu(self)
``` thats what I did for this

then I just check and see, and show which menu depending on it etc

[next ridge]

Found it

if ret == QMessageBox.StandardButton.Yes:
    ...
else:
    ...

my lsp stops working every now and then, making it hard to explore the qt api

[queen trout]

[next ridge]

https://cdn.discordapp.com/emojis/1105114544533160036.webp?size=48

ah

[queen trout]

look at this one

im just gonna restart I think

it just keeps getting worse

lol

what widget is this?
allowing you to move em

[queen trout]

Qt Designer

wait, widget?

List

[next ridge]

lol I didn't even see that u were inside the designer

thought this was inside the app

[queen trout]

nope. You can move them around tho

[next ridge]

is this form layout?

[queen trout]

its grid. And a mix

[next ridge]

i see

[next ridge]

love qt6 on wayland

[queen trout]

whats wayland?

        import traceback

        detailed_dialog(

            "Failed to launch main window",
            repr(e),
            icon=QMessageBox.Icon.Critical,
            detailed_text=traceback.format_exc(),
        ).exec()
        sys.exit(1)

[rigid star]

The only consequence I've noticed is that it pops up in the center of your screen, as opposed to in the center of your parent.

[queen trout]

I'm guessing resizing and location issues also

I want to create an interface overlay over a windows application. My app should stick to that window even when I move it around

Can I use tkinter for this?

and pyautiogui to select the windows e.g

[somber hemlock]

yep

You can create frameless windows with tkinter

[pastel lotus]

That should come in handy then

Thx

[somber hemlock]

The overlay part tho

Some software don't like it

So they can do stuff like killing your process or hiding the gui themselves

[pastel lotus]

I'm using it on Bluestacks

But I'll see what happens

[pastel lotus]

I tried to understand tkinter grid function better by making this example.

import tkinter as tk
from tkinter import ttk

# Open root window
root = tk.Tk()
root.geometry("800x400")
root.title('test')

# configure the grid
for cel in range(8):
    root.columnconfigure(cel)
    root.rowconfigure(cel)

for column in range(8):
    for row in range(8):
        login_button = ttk.Button(root, text=(str(column), str(row)))
        login_button.grid(column=column, row=row, sticky='nesw')

root.mainloop()

What I expected to happen here is 1 button in each grid stretched out, but the result is as follows:

Already fixed it had to add weight = 1 when configuring the row and columns

I have this now, is there a way to make the buttons touch? Like there is no gap in between

[jolly verge]

Your code?

if you use pack/grid, set padx and pady to 0 (or remove them)

[pine glen]

I am self taut and did not find much good on place. Can you tell me the main differance between place and pack and place and grid

[sleek hollow]

place should be avoided 99.9% of the time, it's pretty much useless

absolute positioning is a nightmare if you need to make any adjustments. pack and grid manage the widgets so they're aware of what's around them and will adjust position accordingly

[mint grove]

Guys are any of u familiar with the python flet framework/library

i have seeend videos about it and honestly its better than tkinter pyside6 and PyQT5

although i have only worked with Tkinter ,PyQT and customtkinter

I developing with it now and tbh its better than all the python UI frameworks ever existed

it's two times larger than Tkinter

but they say its still devlopment

it has the multiplatfrom concept

you guys should try it too

I'm currently learning it

here is the documentation

flet.dev

https://flet.dev/

it has the flutter concept to develop apps

but in pythons which im so thankfull for

Tkinter is shit

after i tried this

[sleek hollow]

what don't you like about pyqt?

[mint grove]

iam just saying that flet is better than them in options you get

it has multiplatfrom support too

[pastel lotus]

def home_page():
    home_frame = tk.Frame(main_frame)
    home_log = scrolledtext.ScrolledText(home_frame, font = {"Times New Roman", 15})
    home_log.pack(fill='both', side='bottom', expand=False)
    home_frame.pack(pady=20, padx=20)

Why is my scrolledtext widget filling the entire frame? And not attached to the bottem like I assigned it to.

[placid steeple]

@placid steeple just use documentation/online tutorials, it's much more convenient and efficient

Can i somehow integrate command prompt window in PyQt5 / Qt designer?

All I want is to show output of a .bat file using command prompt that is simulated in my Qt window

[hexed horizon]

@median junco what ide/engine are you using

[somber hemlock]

Use a global mutex

Must be something in threading

[next ridge]

how? and why isn't lockfile working?

[somber hemlock]

How? Let me lookup
Lockfile? Idk

[placid steeple]

onlien tutorials?

Do you have any ones you can reccomend to me

[next ridge]

alr

[hexed horizon]

@placid steeple tutorialpoint and geeksforgeeks both have some nice articles you can follow

[somber hemlock]

Do you want a windows only solution?

Or cross platform

[next ridge]

[somber hemlock]

seems like c++ qt has a QtSingleApplication which has no such thing in pyside or pyqt

[next ridge]

yeh I saw that online, couldn't find it in python lib

[placid steeple]

I will look into both of them thank you (my project is due in 3 weeks lol)

[next ridge]

there's this too tendo.singleton.SingleInstance, uses lockfile i think

it works but idk if I should use it

[hexed horizon]

tkinter is really easy to learn so you should be good ;)

and if you do learn tkinter you should aslo probably know customtkinter, since it looks way nicer and more modern

[somber hemlock]

@next ridge you can use this class as is https://stackoverflow.com/a/12712362/5541355 it involves creating / searching if a local port is open

[next ridge]

which would be faster? lockfile or this port method?

[somber hemlock]

Can't say for sure

But both are equally fast on modern systems

If you wanted a Windows only solution its as simple as creating a named mutex via a simple OS API call

[placid steeple]

yeah thats what the goal is

im learning tkinter to learn how to use customtkinter

https://realpython.com/python-gui-tkinter/

I've been using this as a basis for learning it

[hexed horizon]

real python is great

[placid steeple]

but this specific one has been explaining it as if writing it directly to console

while I prefer to make a demo file which I can look back at when coding

[hexed horizon]

if you have specific problems, tutorialspoint is helpful for that

[placid steeple]

its more kind of like

ive been writing it like this

but I cannot update the text boxes in real life to actually demonstrate these functions

because they happen automatically as the program is run

is there a way for me to sort of run these at my choice of time while the program is running without writing all my code to the console?

Im using pycharm

I tried it in the output but it doesn't really work like that

[placid steeple]

all 3 u sent me are open rn

[hexed horizon]

can you paste your code

[placid steeple]

sure

import tkinter as tk # This imports the tkinter file


window = tk.Tk() # This creates a window for tkinter

def task_1(window):

    greeting = tk.Label(text="Hello, Tkinter") # Creates some Text (A label) to the window
    frame = tk.Frame()

    greeting.pack() # This adds the label to the window!

    # Reminder!!!
    # When you pack a widget into a window, Tkinter sizes the window as small as it can be while still fully encompassing the widget.

    #Label widgets are used to display text or images.


    label2 = tk.Label(
        text="Hello, Tkinter",
        foreground="white",  # Set the text color to white
        background="black",  # Set the background color to black
        width=10, # Sets the width of the label
        height=10 # Sets the height of the label
    )
    # You can also use HexaDecimal Values for colours

    label2.pack() # Adds the label to the window

    # Next we will look into buttons, Buttons are just like Labels but you can click them!

    button = tk.Button(
        text="Click me!", # Defines the text for the button
        width=25,
        height=5,
        bg="blue",
        fg="yellow",
    )
    button.pack()
    # Next is Entrys which are text boxes which users can input text into!

    entry = tk.Entry(fg="yellow",
                     bg="blue",
                     width=50 # This will be the width of how many text units can be entered
                     )
    entry.pack()



# Now we are going to get create a text box which has functions

def entry_box(window):
    label = tk.Label(text="Name") # Creates a text box in which the person cannot edit
    entry = tk.Entry() # Creates a text bot which the user can edit
    label.pack()
    entry.pack()
    #Tkinter automatically centers the label above the entry, this is a feature of .pack()
    name = entry.get() # This gets the contents of the entry text box!
    print(name)
    entry.delete(0) # This deletes a character from the entry text box! In this example it is the first character.
    entry.delete(0, 4) #This deletes all the characters between the 0 and 4th character and is inclusive.
    entry.delete(0, tk.END) # This deletes the all the characters because of the special constant tk.END

    # If the user were to enter "Real Python"

    entry.delete(0, "Python") # This would delete everything up to Python making the text box just "Python"

    # Next is inserting text
    entry.insert(0, "Real") # This would insert real at the start of the text making it "Real Python" once again
    #If the text box is empty it doesn't matter what number you put, it will always place it at the start

def text_box(window):

    text_box = tk.Text()
    text_box.pack()
    # You could run text_box.get(), however it would return an excpetion.

    #If text box contained "Hello World" on a different line for each word

    text_box.get("1.0") # This would return just "H"
    # The index must contain the line and the position of the character on that line when using get for text boxes
    text_box.get("1.0", "1.5") # This would return "Hello", 1 represents the line, and after the "." represents the position of the character
    text_box.get("2.0", "2.5") # This would return "World"
    text_box.get("1.0", tk.END) # This would return "Hello\nWorld\n", "\n" represents a new line.

    # text_box.delete() is used similarly to entry boxes delete
    text_box.delete("1.0") # This would delete the first lines first character making it "ello"

    text_box.delete("1.0", "1.4")
    # When deleting with text boxes you pass two indices to delete a range of characters starting at the first index and up to, but not including, the second index.

    # Even after deleting this you will still

text_box(window)

window.mainloop() # This tells Python to run the Tkinter event loop. It is basically a start command, like bot.run()

It is a lot lol

I like having like a code bank of examples in which I can reference while coding

[hexed horizon]

hmm

make a button

button = tk.Button(window, text='text box', command = lambda:text_box(window)
button.pack()

[placid steeple]

ok

i made a button

[hexed horizon]

when the button gets pressed the command should execute

[weary vector]

why can't i assign a font to a variable with tkinter?

the docs tell me i can use tk.font but vscode is telling me tkinter has no such module

(i renamed it to tk when i imported it)

ok that problem is fixed, but im running into errors with changing the size of the font

i thought i could do MyFont.size(14) to modify the size attribute but apparently not

cause i wanna assign the font family to a variable so that i can change it as I like without having to go through every line to change it

but some text is bigger than other text, and I cant figure out how to make my text size change while keeping the same family

i see that you can call the size by just putting the number in without writing size= , meaning you can write it as tkinter.font.Font("Arial", 20), but then I dont know how i would call that attribute to change it

its even more confusing when i see there is a size attribute RIGHT THERE

[weary vector]

MyFont = TkFont.Font(font="Arial", size=14)

text_result = tk.Text(root, height=2, width=16,
                      font=MyFont.config(size=24))
text_result.grid(columnspan=5)```

basically this is how i wanna use it

is this the correct way?

(the things in there like root which arent defined arent the problem, i just didnt want to copy all my code)

[placid steeple]

oh your right

thank you

[hexed horizon]

you can either use myFont.configure(size=20) or just redefine the variable: ```py
#reference the variable
myFont = tkinter.font.Font("Arial", 10)
#new value
myFont = tkinter.font.Font("Arial", 20)

[weary vector]

the site said it was config bruh wtf 💀

[hexed horizon]

config and configure are essentially synonymous

[pearl meteor]

first = int(input('enter number: '))
operation = input("enter operation: ")
second = int(input('enter number: '))
if operation:
input("*")
print(first * second)
elif

it says there is a problem with elif

[weary vector]

it didnt work

the size isnt changing

heres more of my code for reference

Guys I got a noob question

How do I reach the Frame of class Home from class Menu. Obviously its an object, how do I reach the frame itself?
I want to change a frame on button click like this
command = lambda :app.Show_frame(Home.Frame))
But Home.Frame doesn't work

def Show_frame(frame):
    frame.tkraise()

class Menu(tk.Frame):
    def __init__(self, parent):
        super().__init__(parent)
        
        ButtonOne = tk.Button(self text="Home", command = lambda :app.Show_frame())
        ButtonOne.pack(expand = True, fill = 'both', side='top')

class Home(tk.Frame):
    def __init__(self, parent):
        super().__init__(parent)

Like why can't I just say Home.Frame when I'm in the Menu class

[median junco]

I don't know what "engine" means. I don't use an IDE. I code in vim.

[weary vector]

no one?

[static cove]

You need to hold a reference to Home somehow when you're inside the Menu class or vice versa. For instance, I might approach it like:

class Menu(tk.Frame):
    def __init__(self, parent):
        super().__init__(parent)
        self.parent = parent
        ButtonOne = tk.Button(self text="Home", command = lambda :app.Show_frame())
        ButtonOne.pack(expand = True, fill = 'both', side='top')

class Home(tk.Frame):
    def __init__(self, parent):
        super().__init__(parent)
        self.menu = Menu(self)

so with something like this, if you want to access Home.Frame from menu, it would be: self.parent.Frame
Does that make sense?

[static cove]

That won't work because MyFont.configure(...) doesn't return anything. You're essentially doing
font=None.

I would recommend just creating a new font variable at the size you want and using that.

[weary vector]

alright

at least that makes 2 lines to change instead of like 30

does pyglet accept otf files and not just ttf files? there is a font that i want to add but im having trouble with importing it (its an otf file)

i wanna know if that is the problem or if its something else

ive tried putting it in the same directory as the .py file and adding the whole directory with the add_directory() command, and so far nothing has worked

i cant find anything online telling me if pyglet accepts or doesnt accept otf files

ok even ttf doesnt work

what am i doing wrong

import pyglet
pyglet.font.add_file('lmroman10-regular.ttf')```

these are the only two lines concerned

the name is the exact file name, and the file is placed in the same directory as the .py file

[cedar turret]

Hello, anyone ever encountered this sort of problem in PySide6 before? using QScrollAreas...

myFont.configure() should be its own line of code, not a parameter

[steep ledge]

Hi, I'm new here, just wanted to show you guys a program I made using PyQt5 for a download manager that can download multiple files simultaneously. In order for me to show you what I did, you need to download it. It's just a zip file made from the auto-py-to-exe library to convert my py file to an exe file and zip up the folder containing the program's code. It's not a virus I swear, because every time I post something about a link to download something, people always say it contains a virus. Oh my god, I swear it does not contain a virus, because I just converted the py file to an exe file. So, if you want to check it out, you can. If not, then it's ok too.

This is the link:
https://drive.google.com/file/d/1iPNs1-4QpTbQAA05TgPgSDTGPpV5zuzO/view?usp=sharing

[sleek hollow]

We don't really allow unapproved advertising here, especially to run an unknown exe. If you'd like to share your project's code for something like a code review, it should be a paste link or a github page

[novel shell]

I want to write the code of this kind of design, but I think it is very detailed I can not do it how can I do it or does anyone have interface code in a style similar to this

[sleek hollow]

This could be done using pyqt

@fringe sorrel have you tried changing the color of your label/window?

[fringe sorrel]

yeah

[fringe sorrel]

even tried to close dark mode
nothing worked

[muted hazel]

Looking at the source code, the font support is platform-specific. For example, on Linux it looks like it would use FreeType, which does support OpenType fonts.

[PyQt] Is there an easy way to auto-expand an QLineEdit based on its contents (expand if it doesn't fit)? I'm thinking the only way would be to figure out the contents' width with QPainter.fontMetrics().horizontalAdvance() if that's even possible, but maybe there is an easier way?

And with QGridLayout, it is not possible to auto-determine how much width is available, and wrap rows according to how many columns fit? Or vice versa, wrap columns based on how many rows fit. I suppose it would be possible "manually" if I really need it, but I am not supposed to do that, right?

[sleek hollow]

what app is this youtuber is using? i find it very clean

please ping if you know, thanks!

looks like Sublime Text

[digital rose]

you think?

but it looks very similiar to VS Code tho

idk i'm quite a beginner on python so i like to explore editors

[sleek hollow]

nah, that's definitely not VSC

I use Sublime Text, this is 100% what it is

I don't use that colour scheme though

[digital rose]

ahhh really?

[digital rose]

so i'm using the IDLE

[sleek hollow]

I use this colour scheme

[digital rose]

well the font looks weird

[sleek hollow]

in idle?

[digital rose]

small thing i'm working on

sometimes it's annoying when you can't edit something at the same time if you want

[digital rose]

so that's i was thinking to change

yo

it looks the same now damn

[sleek hollow]

yes, it's definitely sublime

[digital rose]

I see

so is it free like IDLE?

[sleek hollow]

there's a free version

it has most features, and it bugs you to pay every once in awhile

Just be warned that it doesn't support input()

but that's fine since you can run your code from cmd

[digital rose]

well that's bad

for my lil project i'm gonna need that a lot

but thank you so much man

:)

[sleek hollow]

you don't really need input() if you're using GUI

[digital rose]

hm

but i thought if you are going to put in some numbers to convert

in that case i'm sorry like i said, i'm total noob like level 5 experience with python

How does QtQuick compare to QtWidgets? Is it more "troublesome" or less? Do you have to use QML, or can you still do stuff procedurally?

[burnt breach]

this is amazing! thank you! is there a way to do this in QML though?

[inland wedge]

have you heard of the lord and saviour gtk4

[rigid star]

[PyQt] A QScrollArea allows itself to be squished by QSplitter to the same (tiny) size, regardless of its actual widget size - because "well, you can always scroll it". Is it possible to disallow squishing it in one direction below its child widget size? I.e. I only want to scroll it vertically; but horizontally, it must never be below its widget width and force me to scroll! (Disabling horizontal scroll bar does not help - it simply does not show the bar.)

[rigid star]

I'm so dumb. Why does this always happen immediately after I post the question, and not during the hours before that? I was setting the sizePolicy of the widget inside the ScrollArea, and wondering why does that not affect the ScrollArea itself.

the stdlib includes tkinter https://docs.python.org/3/library/tkinter.html .

some people like Qt, some people like GTK windowing toolkits.

i think the standard reply is tkinter. however, the question could be clarified. UI in the web browser could be accomplished in a variety of ways, for instance. in my understanding, this chan is a/b desktop UI, but then again i haven't checked the scrollback.

any qtile fans out there?

[digital rose]

do people use pyinstaller with pyqt or something else to deploy to .exe (and other os)

like, can you deploy a pyqt app to android, what would you use then?

[digital rose]

also, bit of a tangential question but, I've finished a couple of tutorials on PyQtWidgets (and ModelView stuff). but then I discovered QtQuick and it feels confusing:

(1) it seems that everyone is moving away from QtWidgets and applying QtQuick + QML?
(2) not exactly sure how much of PyQt can be actually used with QtQuick
(3) it seems nice for developing mobile apps (but what if I don't want to bother with that?)

(4) looks very similar to kivy, I tried kivy but completlly failed at deploying a "Hello world" as an .apk (tried 3 days at it), why would you use this over kivy

in gtk4 you use the border-radius css property
in gtk3 i believe i saw someone using cairo to do this:

• Here is someone explaining this: https://stackoverflow.com/questions/35480832/create-a-rounded-image-in-gtk
• The gnome music project does this for album cover-s, an example gtk3 release was 3.38

The cairo approach requires creating a widget subclass, implementing the draw function and then creating a cairo surface with your image in, then using cairo function-s to clip the surface.
It is easier in gtk4 where you can add a css class to your image and then in the style.css file you can round all widget-s with that css class.
Perhaps a selector of image.myClass

[hexed horizon]

ehh, tkinter can be a hassle to learn, especially when people tell you to switch to customtkinter or ttk in the middle of learning it. and it definitely has its limitations, so some people decide to use an easier, better-looking alternative like Qt

[burnt breach]

use QML or Qt Widgets. You can create UI using drag and drop (or you could write it in either QML or XML(for Widgets) if you wanna do that)

like i'd like sort of that (sorry for language, i meant only to have a window with 2 or 3 panels where are items being able to be dragged between these panels):

and i'd like something like that in tkinter

sort of a todo list app with two views where i can drag tasks between lists on one window

[burnt breach]

well it seems like you are trying to make drag and drop widgits

[sudden elk]

yep

[burnt breach]

i would recommend QT for this(its literally made for this), but I believe this post has you covered: https://stackoverflow.com/questions/37280004/tkinter-how-to-drag-and-drop-widgets

[sudden elk]

will see cause im too dumb for qt designer and in tk i already made apps…

[burnt breach]

qt is easy

and ui looks better

tk looks ugly like you need to put insane amount of effort to make it look good or import a 3rd party theme

[sudden elk]

like theme i dont care but even qt designer is hard af for me (and where coding all that…)

Hello everyone, I'm learning python, which IDE would you recommend to a backend dev in training?

[inland wedge]

i prefer writing the ui using code, bc then i can implement dynamic behaviour with ease

[inland wedge]

any with a { tree-sitter+ lsp+ dap} backend. Have you used a modal editor before like vim?

[woven lava]

Hey, thanks for your swift response, I haven't used anything before I'm in a career change phase.
I'll look for what you recommend.

[inland wedge]

there are many capable modal editors like neovim which can use modern features however these require time to learn the keybindings
there is good reason to learn an editor with in depth keybinding systems as they are very fast once you learn them but there is that learning curve.
Out of these, i would recommend helix or neovim ( i have heard that emacs is good), they both come with support for pretty much any language

vscode is the only ide i know of with modern features without requiring one to learn many keybinds
i am hesitant to recommend vscode due to microsoft~s monopoly on many industries, i do not want to contribute,
There are probably other easy to pick up editors but vscode is the only one i have used

Ide-s used to be more clunky than they are today, they used to build in support for each language within themselves but nowerdays ,many editors support generic interfaces to different languages so that things such as ( code completion, highlighting, "go to definition") are handled by external software

that software is:

• tree-sitter: provides a quick representation of your code, the editors use this for colouring code and jumping around the document
• lsp ( language server protocol): provides more in depth features such as code completion, the ability to jump around references to a symbol, the ability to rename a symbol and have that rename propagate through the code, ...
  examples are: pylsp ( python), clangd ( cpp, c), marksman ( markdown)
• dap ( debug adapter protocol): provides a generic manner of debugging code, allows one to execute their code and view the program state in order to locate issues with the code

so in short, the modern code editors i can recommend are:
keybind heavy ( fast):

• helix
• neovim
• ( possibly emacs)
  easy to pick up and use, usually graphical:
• vscode ( with microsoft caveat ( vscodium is vscode but compiled without ms telemetery and such))

oh i used pycharm for a lil bit but again it is propriatary, they do have a community edition but it~s main function is to funnel people into the payed edition

Hi, I'm working with Tkinter to make a GUI with a scrollable Text widget, and everything to do with showing things in the widget works, but the Scrollbar seems to keep repeatedly snapping back to the top of the Text widget as soon as it gets pulled down. Any idea what could be causing this?

text = tk.Text(frame, wrap='word', width=40, height=10, font=('Arial', 10))
text.grid(row=0, column=0, padx=20, pady=20, sticky='ew')

scrollbar = tk.Scrollbar(frame, command=data_show.yview)
scrollbar.grid(row=0, column=1, sticky='ns', padx=(0, 10), pady=10)

text['yscrollcommand'] = scrollbar.set

another thing - someone know how to generate list of buttons in tk basing of text file with new lines as button labels?

like i can't generate dynamic variables

and i want sort of :

f = open("file.txt", "r")
num = 0
for line in f:
   $num+button(app, text=line).pack
   num++

while also being able to track such buttons so i can for example do later a condition to check text parameter contents (even if duplicate)

[sudden elk]

and also being able to count how much buttons are generated?

[cyan quiver]

Is kivy still pretty much the go to for mobile development without html/css/js?

[sudden elk]

still no answer…

[sleek hollow]

store the buttons in a list or dict as you create them

[sudden elk]

but how to pack them and display?

f = open("file.txt", "r")
num = 0
num2=0
for line in f:
   $num+button(app, text=line).pack
   num++
for button in buttons:
   if button[text] == *[@,#,$]*:
      $num2+button(frame,text=button[text]).pack
      num2++

like that

[sleek hollow]

import tkinter as tk


button_names = ['foo', 'bar', 'baz']
buttons = []

root = tk.Tk()

for btn in button_names:
    new_btn = tk.Button(text=btn)
    new_btn.pack()
    buttons.append(new_btn)

root.mainloop()

try running this

[sudden elk]

k, will see

ugh…

            items.append(additem)
            items2.append(additem2)

[sleek hollow]

it's telling you what the issue is

you likely don't want text=inititems[item]

you just want text=item

also absolutely do not pack and assign in the same line

additem = tkinter.Button(left,text=inititems[item]).pack(side=LEFT)

additem = tkinter.Button(left,text=inititems[item])
additem.pack(side=LEFT)

what is inititems? Your loop doesn't quite make sense here either

[sudden elk]

anyway - now works, used enumerate

now other problem - i'd like a container to wrap content if bigger than current window size

(config access will fix later)

[sleek hollow]

auto wrapping widgets is actually quite a complex problem to solve. I recommend just using some sort of scrolling widget or fixed grid
