If someone is using PyQt, I usually assume they have a strong understanding of basic python

digital rose
#

well it isn't the first time people tell me i'll have a hard time with something
and they're right, it's just, what am i supposed to give up then, because i'll have a hard time
i mean, with godot for instance, it was extremely hard at the beginning, but eventually i got very used to how signals work and most of the basic functions, that i was able to make scripts almost completely without help eventually
but yes, at the beginnning i had to ask for help a lot, so then i can actually gain some experience

digital rose
#

not as standalone tho

#

until; now

sleek hollow
#

as long as you're aware of where your shortcomings are, you can focus on that area though

#

if you don't know what functions are, that's a good time to brush up on them

#

godot makes extensive use of functions too and it's the exact same there

digital rose
#

i'm assuming functions in this case use def instead of func

sleek hollow
#

yes

digital rose
#

ok pog

sleek hollow
#

but getOpenFileName is a function that PyQt has already defined for you

#

just like move_and_slide()

#

you don't have to define it yourself

#

just like move_and_slide returns a velocity, getOpenFileName returns a tuple

digital rose
digital rose
sleek hollow
#

you need to get that returned value

#

also I'm literally watching a godot tutorial with this discord chat open on my other screen, haha

#

btw can I use a QStandardItem subclass with QStandardItemModel?

sleek hollow
#

what do you mean "can you use it"?

#

QStandardItemModel is a model of QStandardItems

somber hemlock
#

I want to use a font icon for the icon of a QStandardItem. Qt Widgets supports no such thing, so I wonder if I subclass QStandardItem and use two different Label objects with different backing fonts I could get that working

sleek hollow
#

What do you mean by "font icon"?

somber hemlock
#

I have a font which contains icons

#

Like fontawesome for example

sleek hollow
#

so the glyphs of the fonts are what you want to use as icons?

somber hemlock
#

Or those Windows MDL2 assets font

somber hemlock
sleek hollow
#

You could probably do some cheeky workaround using a paintEvent

#

you can "draw" text

somber hemlock
#

I override this for my QStandardItem subclass?

sleek hollow
#

No, you'd need a way of generating the icon elsewhere

#

and then just set that newly painted icon to the DecorationRole

#

actually it doesn't even need to be paintEvent

#

just a QPainter

#

I have to get going in like 2 minutes though or I'd help come up with an example. Seems like a fun challenge

somber hemlock
sleek hollow
#

you need a subclass that will hold the qpainter object

#

subclass QIcon

#

or just create a function that returns a painted Icon

#

you shouldn't even need a whole class for it

#

ok gtg

somber hemlock
#

Bye

digital rose
#

I finally did it

#

i can browse then open images

#

By the way

#

How do i check if stuff are leaking because of the code?

#

in godot, it would tell you if something leaked, but i'm not sure if it tells you here

#

does it?

#

i couldn't show the whole thing accurately because obs only records each window you select, so when i click on the button, it opens a new window, but then i have to make obs detect it, and when i do that, i can't find the window anymore

#

but yea it works

#

now i'll try saving it back

#

so like you could overwrite other images in file explorer with the image you opened

digital rose
#

what does this warning mean?

#

I'm running the py file in Visual studio code now

#

and i got this warning eventually

hey guys, so i figured out how to open a save file dialog, but when i try to overwrite a image with the one i already have open, it doesn't do anything
it tells me are you sure you want to overwrite, but then it doesn't overwrite that image

image.png
sleek hollow
#

the main difference between getOpenFileName and getSaveFileName is the OpenFile has to select a file that already exists, while SaveFile can create new file paths

#

I don't know. Please don't ping me specifically for all your questions

hi, i am using Tkinter to create a GUI, inside it i have a button, whenever this button is pressed a new threading.Thread is created and a long running function is called. What i want to do is when i press tkinter's close button i want to stop this long running thread. is there any better way to do is since threading.Thread does not support thread killing and i am not using any loops inside that function to use events. (ping when answering)

#

Though I'm not certain if that's the best way.

#

Why spawn two processes instead of running Tkinter in the first process, you may ask? Because multiprocessing will try to copy the existing memory into the new process, and that's definitely not something you want

#

Tkinter objects don't support pickling, after all

#

I think
Even if they did you wouldn't want that

somber hemlock
#

I think you can start an empty blank process too

dense elm
#

Maybe, I haven't looked deeply into multiprocessing yet

silver sun
#

It cannot be used with object methods

dense elm
#

Well that's "really unfortunate"

#

but wdym?

silver sun
#

🫠

#

Means the functions which I want to be threaded are inside classes. And when i try to start a process it raises an exception something like pickle ran out of input

dense elm
#

That's what I was talking about initially

#

Use one process for tkinter and another one for the background job(s)

#

Instead of running tkinter in the parent process, run it in a child process

#

Have 2 child processes and make the parent process wait for them

#

to end

silver sun
#

I think i got what you mean to say, will try that, thanks!

dense elm
#

You're welcome

tepid ember
#

what is the best way to output a list of contacts with email, phone number etc using an f string, i have tried many ways and none look nice to look at

tribal path
#

with padding adding or tabulate

tepid ember
#

i just have the information displayed on different lines rn

first name:
surname
number

and so on

tribal path
#

tabulate should be getting padding values for you for the whole dataset

tepid ember
#

would you be able to provide an example?

#

of how you would use tabulate for a similar scenario

tribal path
#

would be just passing the list to tabulate, what structure is the list in

tepid ember
#

ooh, i did not know there was a tabulate module in python

#

let me just research this real quick

i figured out how to save png files, but when it saves it, the png file doesn't have anything inside it

image.png image.png
dense elm
somber hemlock
#

the last line of your show_pic method is also unnecessary

digital rose
#

Well mostly

#

There are transparency issues when saving a png photo as jpg

#

But otherwise seems to work pretty much fine

somber hemlock
#

Use PNG its a better format

digital rose
#

Lel

#

Well I can save image as png or jpg

#

But never knew or forgot that jpg doesn't have transparency

somber hemlock
#

WebP is the best of them, very efficient

digital rose
#

Webp sounds like a format you'd only use for viewing photos in the internet

#

Like webm for video files

#

Why is it called webm

somber hemlock
#

It was invented for that purpose, but its compression ratios are unbelievably good

#

You take a png and webp of the same resolution you see a very different size for both of them

digital rose
#

What about webm

#

Is it efficient

somber hemlock
#

Should be

digital rose
#

One thing I don't get about video files is why can't you have regular transparency in them?
You can have regular transparency in png, gifs, a lot of other formats, but for some reason with video files, you need to use green screen, etc

#

I don't get that

Hey there Everyone,
I am currently using PySide6 as my GUI lib.

I Am looking at creating a menu bar on the QMainWindow widget but I was thinking about putting it in a separate file so I can compartmentalize each stage of the UI.

I Currently have this for the main_window.py file

from PySide6.QtWidgets import QMainWindow


class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("JLS: Houdini package manager")

        self.setMinimumWidth(350)
        self.setMinimumHeight(400)
        
        self.create_menu_bar()
        
        # self.menuBar().addMenu("File")

    def create_menu_bar(self):
        from GUI import window_menu_bar

        window_menu_bar.CreateMenu(self)

And for the menu_bar.py file I have the following:


class CreateMenu():
    def __init__(self):
        super().__init__()
        self.menuBar().addMenu("File")

QUESTION
I was wondering, is there a way to pass through the class of MainWindow() ?

#

I know I could inherit from MainWindow() But I keep getting a recursive error Which makes sense. Im just not sure how to get around that 🤔

Why is discoverability in an application interface important?
A. It prevents users from making mistakes.
B.It helps users understand what things can be accomplished with the interface.
C.It allows new users to find more advanced ways of using the application.

from PyQt5 import QtWidgets

class MainWindow(QtWidgets.QMainWindow):

    def __init__(self):
        super().__init__()
        self.menu_bar = CustomMenu()
        self.setMenuBar(self.menu_bar)


class CustomMenu(QtWidgets.QMenuBar):

    def __init__(self):
        super().__init__()
        self.addMenu('File')
        self.addMenu('Settings')
        self.addMenu('Help')


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

something like this

#

just CustomMenu would be in its own separate file

#

exact same implementation though

#

also my example is pyqt5 instead of pyside, but still the same

hello, why when i import a python tkinter file that contains root.mainloop() , when i run the file where i imported it just runs until the import and start the app without executing other codes. Here is a simple example :
gui.py

root = customtkinter.CTk()
root.geometry("900x600")
root.title("Example By: Lvvz")
label = customtkinter.CTkLabel(root, text="User").pack()
root.mainloop()```
secondfile.py
```py
from gui import root, label
print('this doesn't print')```
it runs the root.mainloop() that in gui.py because i imported it, i hope you understand.

I'm trying to make a simple graphing calculator in tkinter with matplotlib using the canvas imported using

matplotlib.backends.backend_tkagg import FigureCanvasTkAgg```
The canvas doesn't redraw properly until I manually change the window, I tried using ```py
canvas.get_tk_widget().event_generate("<Configure>")

to force it to redraw properly but it didn't work.

I did manage to fix it using

w, h = window.winfo_width(), window.winfo_height()
window.geometry(f"{w+1}x{h}")
window.update()
window.geometry(f"{w}x{h}")

however this seems a bit inelegant and causes issue in full-screen
Any idea how I can make the canvas draw properly?

For reference the canvas should look like this (this is after resizing the window by one pixel and then setting it back)

yes, tkinter is definitely easier than pyqt

and depends how much you know about oop

but overall pyqt is far more robust

CustomTkinter is an improvement though for better looking widgets

but as mentioned above, it takes work to do so. Vanilla widgets for any of these packages won't look great, but they're very customizable

pyqt can use css stylesheets

and qt widgets can only get you far upto a certain level

What's the easiest way to send a message from a child process to the parent, portably? I have a tkinter app that starts another Python app, and I need it to send a URL back after it's started. That child app does use its stdout/stderr for messages to the user so I can't just use that

#

I don't think I can open another pipe portably, that probably doesn't work on Windows

#

I could give it the path to a temporary file, or open a TCP socket, but that seems rather involved. Is there a super easy way to pass back a tiny bit of information once?

somber hemlock
#

and they work on all platforms

from multiprocessing import Process, Pipe

def f(conn):

if __name__ == '__main__':
    parent_conn, child_conn = Pipe()
    p = Process(target=f, args=(child_conn,))
    p.start()
    print(parent_conn.recv())   # prints "[42, None, 'hello']"
    p.join()

You can replace f with the imported entrypoint of your child process

Hi all, I'm looking at using Kivy for a project of mine, part of which includes having a CodeEditor inside of a TabbedPanel's tab, I'll have a few of them hardcoded in

I'm currently using the Builder.load_string() function with the following text

Builder.load_string("""
<EditorWidget>:
    do_default_tab: False
    
    TabbedPanelItem:
        text: 'Bios'

            lexer: NasmLexer
            style_name: 'colorful'
""")

For some reason, if I create a CodeInput with manually assigning lexer=NasmLexer(), then it is perfectly fine
But when I do it with the Builder, I get the error NameError: name 'NasmLexer' is not defined
Could someone please help me as to why this is occuring?

Are there any resources to help one decide which gui framework to use? I've done some searching online and found:

  • The QT libraries generally cost money (but QT Designer is available)
  • Kivy's selling point is touch controls and mobile, but I'm pretty sure it can also do desktop. Though for desktop, I'm not sure why I'd pick it over another

Before I start listing out all the others, assuming I'm just looking to make a desktop gui, are there any tangible reasons to use anything over TKinter? I'd think since it comes with the python install...it's the most simple to use that? But my gui experience is very limited. Thus far, I've only used TKinter for the "openFile" dialog box.

Any suggestions, or personal opinions are welcome.

somber hemlock
# teal fable Are there any resources to help one decide which gui framework to use? I've don...

Qt (PySide6) is dual licensed under LGPL and a proprietary license. If you go open source, you can use Qt for free.
From my personal experience:

Qt:

  • Easiest to find help for (next to Tkinter)
  • Nicely documented, most sane choice if you have used it un C++
  • Overly bloated (its huge)
  • Not very Pythonic
  • You won't be using most of its features.

Kivy:

  • Pythonic API
  • Minimal dependencies
  • KV language
    - Immensely complex for basic things at times
  • No type hints
  • Default look and feel is outdated Android.
  • Rare updates, less maintained
  • Outdated or plainly inadequate docs.
  • Hard to find help for.

Which GUI library you should consider depends in what you want to make. Tkinter is adequate enough if you don't want to invest a significant time experimenting and learning stuff. It has a lot of problems, but its the easiest to get help about.

teal fable
#

Thanks! When you say "depends on what you want to make" beyond answering (and this isn't meant as snarky) "an app that runs on Windows that has an end user interface" which I would think (just about) any gui framework can do, it's hard to differentiate one vs. another. For example, let's say I picked framework "X" and someone asked me why...my best answer currently would be...because I wanted to play with the framework. I wouldn't really have any reason or justification.

Each UI lib has its strengths and weaknesses. You gotta pick the right tool for the job.
For small tool / utility, Tkinter would be adequate, but think of anything real world, it sucks.
Qt can pull off everything you can imagine, but Qt is a C++ library. The chances of finding something for Qt C++ is much higher.
I wouldn't recommend Kivy, its not exactly easy and quite untuitive, but you might find it easier if you have done Android dev.
If you want something that looks clean and modern out of the box, try flet.
If you have some data rich app, where you need to draw a lot of charts, plots, nodes etc, try dearpygui
If you want a very native looking UI, try wxPython. It uses native controls, so on Windows it looks like a classic old Windows app

can i have a combo keyPress as event for tkinter?

#

like shift + enter?

sleek hollow
#

<KeyPress event state=Mod1 keysym=x keycode=88 char='x' x=113 y=110> this was the event for pressing X on my keyboard

#

<KeyPress event state=Shift|Mod1 keysym=X keycode=88 char='X' x=113 y=110> and this was the event for shift+X

ruby crystal
#

i haven't seen many of theses before
sorry

sleek hollow
# 
import tkinter as tk 

def keypress(evt):
    print(evt)

root = tk.Tk()
root.bind('<KeyPress>', keypress)
root.mainloop()
#

this was my entire code to generate that print-out

#

if you do evt.state, you'll get the modifiers held, which are represented as ints

#

do print(evt.state) and see what the results are and then you can check for that int when looking for certain keypresses

#

8 is "no modifiers"

#

9 means "shift was held"

# 
import tkinter as tk 

def keypress(evt):
    if evt.state == 9 and evt.keycode == 88:
        print("Shift X was pressed!")

root = tk.Tk()
root.bind('<KeyPress>', keypress)
root.mainloop()
ruby crystal
#

like what is state, keysym, keycode, char, x, y

sleek hollow
#

state is what modifiers were held, keysym is symbolic of what key was pressed. char is the text of the key pressed (not all keys have this)

#

x and y is where your mouse cursor was when the event happened

#

try printing out the event and pressing buttons on your keyboard and see the results

#

you can make your own observations like this 🙂

ruby crystal
#

ok i'm getting some of it now

sleek hollow
#

There's no need to memorize all the keycodes and states. If you're looking for a certain combo, then print the event, do that combo on your keyboard, note down the results, and then now you know the combo to look for if you want that specific keypress

ruby crystal
#

mm
can you tell me the difference between modifiers and keysym?

sleek hollow
#

modifiers is a combination of all the the modifier buttons that were held at the same time. shift, alt, ctrl

ruby crystal
#

mod is the one we keep and keysym is just one press?

sleek hollow
#

those are the modifiers

#

state is the modifiers

#

try printing out event.state

#

and pressing different combos of these

#

these are keysyms

#

the text representation of the button pressed on your keyboard

#

keycode is simply an int representation of the key you pressed

#

print out keysym and keycode together to see this

ruby crystal
#

mmm
this is interesting

ruby crystal
# sleek hollow

state=Mod1|0x40000 keysym=Alt_R why do i get this when pressing right alt?

sleek hollow
#

I wouldn't worry too much about what it says after state=

#

just do event.state to get the proper int

ruby crystal
#

so in order to get a shift + enter event
i should set the state to shift and keysym to return?

#

or i'm way off? 🙂

sleek hollow
#

tell the function to print event.state. Then press shift+enter. Note down what the printed value was

#

It's a little confusing because you'll likely see 8 first, which means "no modifiers"

#

this is because when you pressed shift, you weren't holding any other modifiers

#

but shift plus any other key will have a state value of 9

#

so if I print keysym and state, I get this

#

don't just test 1 key. Hold shift and press a bunch, and you'll see they all have a state of 9

ruby crystal
#

okay thank you
but how is the syntax of writing mod and keysym?

sleek hollow
#

use keycode instead of keysym

ruby crystal
#

no i got that part

#

but if i want to write an event

#

like <shift_l-return>
or..

sleek hollow
#

what do you mean "write an event"?

#

then you could use keysym

#

the combos are bitwise combined

#

so alt is 131080

#

shift is 9

#

alt+shift is 131081

#

!e

print(131080 | 9)
proven basinBOT
#

@sleek hollow :white_check_mark: Your 3.11 eval job has completed with return code 0.

131081
sleek hollow
#

you could create a dictionary of all these combinations if you like

ruby crystal
#

btn.bind("<131081>", pressed)
would do alt+shift?

sleek hollow
#

no, always bind to KeyPress, and then check for the event in the function

#

binding to buttons isn't a great idea since they need focus to perform their bind action

#

if you're trying to make a shortcut for a button, just bind it to root and have the bind call the same function that the button would (after checking for key combo)

# 
import tkinter as tk 

def hotkey_pressed(evt):
    if evt.state == 9 and evt.keycode == 13: #Shift + Enter
        button_action()

def button_action():
    print("Button clicked")

root = tk.Tk()
btn = tk.Button(text='Click me', command=button_action)
btn.pack()
root.bind('<KeyPress>', hotkey_pressed)
root.mainloop()
#

now the button click OR the hotkey both lead to the same result

#

you could have one function responsible for all your hotkey combos and their resulting actions

ruby crystal
#

ok this was really useful
searched many web sites and didn't get any of this :/

thank you🙏

Don't do anything from non-Tkinter callbacks, as you can't be sure of their thread context.

That might be it, I'm creating a new window from an on_press callback from pynput

#

So how should I do it? Create it first and hide it and only show it on the on press condition?

somber hemlock
#

Use a queue, which notifies the UI thread to do operations

#

in your callback, push a message to your queue. Make a function in your UI thread which regularly polls this queue for a new item. Do the polling with tkinter.after

#

But first really verify what causes that error

#

I would just start using some print messages to debug the path that your code is taking through the logic you've laid out

#

and hopefully can catch something happening incorrectly

#

The way you're using self.update_textEditBox is a bit odd though

sly topaz
sleek hollow
#

I'm also not too familiar with pandas so I'm not sure if the function is even being applied correctly

# 
if isinstance(value, str) and (value.endswith(" ") or value.startswith(" ")):
                            self.result = sheets + ": " + value



                            self.con_res_txt = str(self.result)

                            self.update_textEditBox(self.con_res_txt)

                        else:
                            self.update_textEditBox('No Errors')
#

your if/else will either append data to the text box, or completely clear it out and say "no errors". This isn't super reliable to do inside a for loop

#

since only the final result will be apparent

#

Also sorry but I need to head out for a bit

this all can be condensed into a single row of controls. You can remove the "your text" label. Use an icon for the gender and slow motion option. It will speak on pressing Enter.
You can make it a floating window which become translucent when out of focus, remove the titlebar, add a keybind to escape out
You can also make the text entry a combobox which shows the history.

So I'm trying to add scrollbars to a tkinter window and I'm sure I'm doing something dumb but this just doesn't seem to work:

    window_outer = tk.Toplevel(root)
    info_windows[rid] = window_outer
    window_outer.geometry("500x800")
    window_outer.title = f"Patient #{recdata['PatientID']}"
    bary = tk.Scrollbar(window_outer)
    bary.pack(side='right', fill='y')
    window = tk.Canvas(window_outer, yscrollcommand=bary.set)
    window.pack(side='left', fill='both')
    bary.config( command = window.yview)
#

Am I missing something obvious here?

#

The scrollbar is there but it's greyed out and disabled like you can see the whole canvas (when you definitely can't)

how can I create widgets programatically

like, I want my QDialog to have a check box and label for each value on a list

#

I managed to do it tho, thanks

covert rock
#

how can I create a QGridLayout that is scrollable in a QDialog window?

sleek hollow
covert rock
#

this is the window I have

image.png
#

it's being generated like this

# 
class MngSubsWin(QDialog):
    def __init__(self, num, parent=None):
        super().__init__(parent)

        self.setWindowTitle("Manage Subs...")

        lorem_ipsum = [
            "Lorem ipsum dolor sit amet",
            "consectetur adipiscing elit",
            "Sed venenatis, ex nec euismod dignissim",
            "neque eros molestie nunc, nec fermentum",
            "massa arcu quis enim",
            "Nullam vestibulum vehicula",
            "metus ut volutpat",
            "Morbi pretium felis ut leo eleifend"
            "eget porttitor nunc sollicitudin",
            "Fusce ac tincidunt elit"
        ]

        self.main_layout = QGridLayout()

        cnt = 0
        for e in range(num):
            self.checkbox = QCheckBox()
            self.series_info = QLabel(lorem_ipsum[e])
            self.main_layout.addWidget(self.checkbox, cnt, 0)
            self.main_layout.addWidget(self.series_info, cnt, 1)
            cnt += 1

        self.main_layout.setAlignment(Qt.AlignTop | Qt.AlignLeft)
        self.setMinimumSize(QSize(300, 24 * self.main_layout.rowCount()))
        self.setLayout(self.main_layout)
#

how do I place that layout inside a QScrollArea?

sleek hollow
covert rock
#

thank you so much 😁

sleek hollow
covert rock
#

it would so much easier if QDialog had a setCentralWidget method

#

but it works

#

that's what matters

sleek hollow
#

I almost always use a vboxlayout as my primary qdialog layout

#

and then just add whatever to that

#

you could set a single QWidget to that layout and then nest from there

covert rock
#

yeah, it's the wrapping my head around it that it's a bit of a struggle

sleek hollow
#

but yes, I do agree, scroll areas are a pain, haha

#

You could make a subclass for it and save yourself a bit of pain if you need multiple scroll areas

covert rock
#

now, I need to figure out how to programatically get those programatically generated boxes and labels signals

covert rock
sleek hollow
#

you could create a custom signal and connect your dialog to it

covert rock
#

not there yet

#

I'm still learning Qt

#

while doing what I want to do with it

#

basically, the idea is to have check boxes and labels

#

then the user would check the boxes related to items they want to delete

#

the way I'm thinking is

sleek hollow
#

Pretty much any time you need to repeat a feature into your UI, it should be subclassed

covert rock
#

to create a slot that will read the location in the grid that the marked check box is, then just move one column to the right and read the label there

sleek hollow
#

also although grid layout works for what you're doing, I would recommend QFormLayout in the future

#

it's built pretty much exactly for this "text/widget" row setup

covert rock
#

no no

#

not in this case

#

this is what you mean right?

sleek hollow
#

yeah

covert rock
#

nah, this isn't what I want

sleek hollow
#

what are you ultimately trying to do?

covert rock
#

at least I don't think so

sleek hollow
#

It works with checkboxes too

covert rock
#

basically

#

this QDialog is to show the currently subscribed mangas the user want to be notified of. then the user would check the boxes of the subscriptions they want to delete than hit okay to unsubscribe

sleek hollow
#

Yeah, that would be perfectly fine to use QFormLayout

covert rock
#

yeah

#

so it seems

#

it has these, which grid doesn't

sleek hollow
#

I would always try and avoid getting widget details based on location

#

it's not very reliable

covert rock
#

how can I get them though, without a variable name? since they are being added programmatically?

sleek hollow
#

store them in a list

#

and iterate through the list

#

one sec, I'm doing an example

#

with subclassing

#

it makes everything so much easier to manage

            self.inner_layout.addWidget(pair[1], cnt, 1)
            cnt += 1
sleek hollow
#

Subclassing in my example makes it so much easier to keep track of the label and checkbox as a single unit

#

You also then don't even need a grid layout or form layout

#

they just get treated as a single widget that can be placed in something like a vbox layout

covert rock
#

I'm still trying to understand

#

give me a minute lol

#

ah okay.

sleek hollow
#

sure, let me know if you have any questions

covert rock
#

so LabelCheck is just stacking inner HBoxLayouts inside MainWindow's VBoxLayout every time it's called

sleek hollow
#

LabelCheck inherits from QWidget

#

QWidget is essentially an empty container

#

So the LabelCheck class is a simple QWidget with an hboxlayout that displays a label and a check

covert rock
#

and since the things inside self.label_checks are objects with their own memory addresses, you can just iterate and use the isChecked and get_label_text methods on each one

covert rock
sleek hollow
#

just wanted to clarify that it's stacking widgets, not layouts

#

I could just as easily set LabelCheck to use VBoxLayout, it just won't look as good

covert rock
#

but those widgets aren't being added to a hbox and that hbox isn't being added to the main window vbox?

#

so you're basically stacking multiple layouts inside the main window layout, right?

sleek hollow
#

the contents of the QWidget are irrelevant to the main window

#

all the main window's vbox is saying is "stack these widgets"

covert rock
#

that's my doubt

sleek hollow
#

QWidget is like an empty box, ready to have things added to it

covert rock
#

it may be an irrelevant question but

#

you aren't stacking widgets right? the subclass is packaging them in a hbox before they are passed to the vbox, aren't them?

sleek hollow
#

no, the hbox is inside the qwidget

covert rock
#

ahhhhhhhhhhhhhhhhhhhhhhhh

sleek hollow
#

self.setLayout(QHBoxLayout())

covert rock
#

okay

#

yeah now I get it

sleek hollow
#

QWidget's can have a primary layout

#

which is set through .setLayout

#

and then any further layouts must be nested under there (but my example only has 1)

covert rock
#

ah okay

#

so, if my understanding is correct

#

LabelCheck is really just a renamed QWidget class

#

and each instance of it is a QWidget with the check box and the label in it

sleek hollow
#

exactly!

#

but because we've subclassed it like this, we can create our own methods for how we want to interact with it

covert rock
#

yeah

#

man OOP is wack

sleek hollow
# 
    def isChecked(self):
        return self.check.isChecked()

    def get_label_text(self):
        return self.label.text()
#

this makes it really easy to determine if this "widget" is checked, and what the label text says

covert rock
#

yeah because you're working on the object

#

I'm still dipping my toes on OOP

#

it's really useful, but it's quite a bit of a mental shift from just using functions like I've been doing

sleek hollow
#

Yeah it can definitely be overwhelming

#

but especially with GUI, it's important to identify when you'll want to subclass

#

any reusable component should pretty much always be a subclass

covert rock
#

yeah

#

in this case

#

the subclasses is more for ease of use

sleek hollow
#

yeah absolutely

covert rock
#

because this will be the only window where this will be used

sleek hollow
#

you could have done it without subclassing

covert rock
#

in this QDialog

sleek hollow
#

but then you'd have to manage your labels and your checkboxes and find a way to keep them in sync

covert rock
#

yeah

sleek hollow
#

whereas with a subclass, it already self-contains all that information

covert rock
#

I guess I will finally take that OOP book seriously and read it

sleek hollow
#

As you do more GUI work, you're likely to end up with a collection of really useful subclass components

covert rock
#

from O'Relly

sleek hollow
#

so you don't have to reuse them every time you make a new ui

covert rock
#

yeah

#

do you know how to program in C++?

sleek hollow
#

nope

covert rock
#

because finding examples for qt in python is paltry in comparison with the abundance of c++ examples

sleek hollow
covert rock
#

but I have no knowledge of it lol

sleek hollow
#

it's way more organized and easier to navigate

#

all that really matters is the method names

#

it's the same between c++ and python

covert rock
sleek hollow
#

I've really only used pyqt5 and pyside2

covert rock
#

I'm using pyside6

sleek hollow
#

I have to stick with pyside2 for work

covert rock
#

things didn't change too much from pyqt5

#

just the docs that got a lot better

#

for the primary binding

#

which is pyside6

covert rock
sleek hollow

then I'm staying with this

class MainWindow(QDialog):
    def __init__(self):
        super().__init__()
        self.main_layout = QFormLayout(self)
        for i in range(10):
            self.main_layout.addRow(f'Label {i + 1}', QCheckBox())

        self.view_btn = QPushButton("View Checked")
        self.view_btn.clicked.connect(self.on_view_btn_clicked)
        self.main_layout.addWidget(self.view_btn)

    def on_view_btn_clicked(self):
        for row in range(self.main_layout.rowCount()):
            checkbox = self.main_layout.itemAt(row, QFormLayout.FieldRole).widget()
            if checkbox.isChecked():
                label = self.main_layout.itemAt(row, QFormLayout.LabelRole).widget()
                print(label.text())
#

same end result

covert rock
#

but in this case

#

there wasn't a need for a subclass

sleek hollow
#

yeah

covert rock
#

and it seems more tidy too

sleek hollow
#

We can use FieldRole and LabelRole to get the widget and label of each row in the form

covert rock
#

the check box would be field or label role?

sleek hollow
#

field

covert rock
#

so field is the widget in the form layout

sleek hollow
#

exactly

covert rock
#

gotcha

sleek hollow
#

so in general, there's multiple ways to approach a task

covert rock
#

yeah

sleek hollow
#

it's up to you to use the tools you know to achieve it

it's a pull notification system for a manga aggregator

they don't have an RSS or push notification system yet

but they have a great API

so I wrote a small beta to be able to get toaster notifications each time a manga I follow is updated

sleek hollow
#

oh neat!

covert rock
#

it's a hastely cobbled together thing

#

but I did learn a lot about interacting with apis and doing http requests

#

now I'm doing the major refact , better UI, and more features for the 1.0.0 version

covert rock

this is what I did

        self.inner_layout = QFormLayout()

        for e in range(num):
            self.checkbox = QCheckBox()
            self.series_info = QLabel(lorem_ipsum[e])
            self.inner_layout.addRow(self.checkbox, self.series_info)

        self.inner_layout.setAlignment(Qt.AlignTop | Qt.AlignLeft)

        self.container_widget = QWidget()
        self.container_widget.setLayout(self.inner_layout)

        self.scroll_area = QScrollArea()
        self.scroll_area.setWidget(self.container_widget)

        self.delete_button = QPushButton("Delete Subscriptions")
        self.delete_button.clicked.connect(self.delete_subs)

        self.outer_layout = QHBoxLayout()
        self.outer_layout.addWidget(self.scroll_area)
        self.outer_layout.addWidget(self.delete_button)

        self.setMinimumSize(QSize(300, 24 * self.inner_layout.rowCount()))
        self.setLayout(self.outer_layout)

        def delete_subs(self):
            for row in range(self.inner_layout.rowCount()):
                checkbox = self.inner_layout.itemAt(row, QFormLayout.LabelRole).widget()
                if checkbox.isChecked():
                    label = self.inner_layout.itemAt(row, QFormLayout.FieldRole).widget()
                    print(label.text())
#

getting this error

#

AttributeError: 'MngSubsWin' object has no attribute 'delete_subs'

#

MngSubsWin is the class this is in

sleek hollow
#

delete_subs shouldn't be nested in whatever method you're currently in

#

it should be at the same level

covert rock
#

ah damn it

#

it was still inside init

#

sorry lol

#

stupid me

sleek hollow
#

are you trying to remove/delete the row when it is checked?

covert rock
#

no

#

it will read the label for the manga series name, then delete the instance with that series name from Mangas class, then delete the related dict with the manga info from the json, then save the json

#

and hell yeah I'm subclassing all of this shit

sleek hollow
#

is there a reason the instance needs to be deleted? What if they check the button again? It has to generate a new instance?

#

Seems like you should simply leave all the instances intact and then use the checkboxes to determine what should be skipped when saving

covert rock
#

it will only delete if they click the button to confirm after checking the box

sleek hollow
covert rock
covert rock
#

I'm showing that it's a lot of stuff, so I'll subclass to make it tidier

sleek hollow
#

ahh yeah

covert rock
#

it's based on those dicts that I populate the Mangas class

#

and it's only populated and checked once at the start of the program

#

if I don't delete the instance, then it will keep pinging the API about that series, even if the user is not subscribed to it anymore

#

the way I figure, it's better to just purge the unnecessary memory space

sleek hollow
#

oh ok, that makes sense then

class MainWindow(QDialog):
    def __init__(self):
        super().__init__()
        self.main_layout = QVBoxLayout(self)

        self.main_layout.addLayout(self.label_layout)

            if wdg.isChecked():
                to_delete.append(wdg)
        for wdg in to_delete:
            wdg.deleteLater()      


class LabelCheck(QWidget):

    def __init__(self, text):
        super().__init__()
        self.setLayout(QHBoxLayout())
        self.label = QLabel(text)
        self.check = QCheckBox()

        self.layout().addWidget(self.label)
        self.layout().addWidget(self.check)

    def isChecked(self):
        return self.check.isChecked()

    def get_label_text(self):
        return self.label.text()


if __name__ == '__main__':

    app = QApplication([])
    win = MainWindow()
    win.show()
    app.exec()
#

this is how I would handle the deleting

#

I didn't rename the method name, but it deletes whatever is checked now

#

and instead of storing the LabelCheck instances in a list, it uses the children of the layout (which will only have those instances added to it)

covert rock
#

I mean

#

in this case, that isn't necessary

#

because when the user presses the delete subscription button

#

the qdialog will delete the instances, delete the dicts, save the json and close

#

so the next time the qdialog is open

#

it will only show the current instances of the Mangas class

#

so I don't need to delete the rows

Does anyone have an image/video viewer or sorter program in pyqt? Id like to see one as a reference to see what improvements i can make to my own project

somber hemlock
mellow hemlock
#

I did manage to find 2 and holy crap they are using sooo many stuff i have no idea about 😆

#

i found this main.ui file in one of the github programs i downloaded

image.png
#

what language is this and what is it for?

#

and how is it incorporated into pyqt

mighty rock
#

Looks like XML. It stores configurations between opening and closing tags

mellow hemlock
#

Do i need to learn that as well? Or is it just something like an addon to beautify pyqt

sleek hollow
#

Instead of manually coding all the UI widgets, you can use Qt Designer to drag and drop build a UI and it spits out this .ui file

mellow hemlock
#

Oh wow i only started learning pyqt 4 days ago so have only used qt designer a few times

#

So i dont need to learn the xml formatting and all right

sleek hollow
#

I honestly don't recommend it (designer) to beginners. You're better off learning how widgets are created/placed manually first

sleek hollow
mellow hemlock
#

ah thats neat then

#

btw what function do i need to call to display webp files

#

because it falls neither in the pixmap nor in the movie

sleek hollow
#

not really sure, I've never had to deal with that before

mellow hemlock
#

I making an image/video sorter and the webp images are giving me a headache XD

sleek hollow
#

that's a pretty advanced place to start if you're just starting with pyqt

mellow hemlock
#

i was able to make it using the vlc library before so i thought why not use a gui instead

#

so tried to learn pyqt

#

yeah pyqt is a bit hard to read 😅

sleek hollow
#

There's definitely an overwhelming amount of info/features

#

I always recommend the C++ docs though over the python ones

mellow hemlock
#

tinker had a very old windows XP style ui and i didnt really like it

#

thats why i sticked to pyqt

worthy dew
#

is there a document on pygame.org for a scrollable surface?

mellow hemlock
sleek hollow
#

one video definitely isn't enough. I've been using pyqt for nearly 2 years and I'm still learning a ton of new things

mellow hemlock
#

how do you even read the documentation tho, i havent really tried learning that way before

#

do i just skim through every single commands and see if it is useful?

sleek hollow
#

All that's really important is the methods/signals/slots

#

So you learn how to interact with that widget

mellow hemlock
#

hmm

#

do you know any website that has pyqt example projects then?

#

ig i can just learn by doing

this first link is a good tutorial project

#

ooh awesome!

#

ill try that one out today then

#

btw there is one question i had

#

is there a way to make it so that there is a + button which adds more buttons on the screen that also scales to according the the number of buttons?

#

i was thinking of having a + button to add more options on how to sort/move the files

#

so that it would be more configurable in the gui

#

instead of going inside the code for each button

sleek hollow
#

You can pretty much do anything you want, you'll just need to code these exact features yourself

mellow hemlock
#

ah makes sense

sleek hollow
#

What are these buttons?

#

the thumbnails?

mellow hemlock
#

like button 1 to move to folder x
button 2 to move to folder y
and then a + button to add more options

mellow hemlock
sleek hollow
#

If you want a bunch of selectable images, you should likely be using listwidget instead

#

it has a toggle for text or image mode

mellow hemlock
#

ooh alright

#

will look into ti!

#

and one last things, what is the super().__init__

#

😅

sleek hollow
#

do you know what __init__ is?

mellow hemlock
#

techwithtim wrote that as if expecting the viewer to already know about it so i was confused if i missed something

#

i think i do? its for initialising a class right

sleek hollow
#

yes

#

When you inherit from a class, you gain access to all of its methods as well

#

However, when you define a method with the same name as the parent class, it is overwritten

#

this is even true for def __init__

#

however, we can use super() to allow our class to call up to the parent and access its original methods

#

so if you have a class that inherits from QMainWindow, you need to make sure that QMainWindow's __init__ is called or it won't be configured correctly

mellow hemlock
#

so here is what i understood

class example():
  def method(self): 
    self. something code

class example2():
  def __init__(self):
    super(example, self).__init__()```
#

the example 2 class will inherit the methods of example class?

sleek hollow
#

class example2(example)

#

you have to specify the class you want to inherit from

mellow hemlock
#

oooh gotya

sleek hollow
#

class MyGUI(QMainWindow)

mellow hemlock
#

ooooh right makes sense now

#

yeah the code has somethign similar to that

sleek hollow
#

this isn't just for init, but any method you need to overwrite

#

(if you also want the original behaviour)

mellow hemlock
#

init will just inherit all methods right

sleek hollow
#

no

#

it does that anyways

mellow hemlock
#

its more for overwriting?

sleek hollow
# 
class MyWindow(QMainWindow):
    pass
#

if I have this super basic class

mellow hemlock
#

yeah

sleek hollow
# 
window = MyWindow()
window = QMainWindow()
#

these 2 lines would be practically identical

mellow hemlock
#

oooh yeah

sleek hollow
#

MyWindow has the exact same behaviours as QMainWindow

mellow hemlock
#

go on

sleek hollow
# 
class MyWindow(QMainWindow):
    
    def __init__(self):
        pass
#

but if I were to do this

#

then I've now overwritten QMainWindow's __init__ and now when the instance is created, nothing is being configured correctly anymore
