[sleek hollow]

When using an inherited QAbstractListModel, is it possible to return only a height for SizeHintRole?

Without any size hint, my listview properly adds a scrollbar when needed for width, but I'm not happy with the height of my items. I want to change my item height but let the width still smartly calculate what's needed

[mighty frigate]

@sleek hollownope. The size hint is something Qt itself uses and it needs to return what Qt is expecting

@sleek hollowthere's 3 things I'd try to do that:

• create a subclass of QStyledItemDelegate, and overwrite the sizehint() function, call the parent function there to retrieve the correct width and calculate the height you want. It should look something like this :

def sizeHint(self, opt: QStyleOptionViewItem, index: QModelIndex):
    item_size = QStyledItemDelegate.sizeHint(opt, index)
    # modify item_size here
    return item_size

• Another that might just work is modifying all default item height using the stylesheet of the view

view = QListView()
view.setStyleSheet("""
QListView::item {
    height: 100px;
}
""")

for reference, the stylesheet documentation : https://doc.qt.io/qt-5/stylesheet-reference.html

• Lastly, modify your parent model data() function to retrieve the parent sizeHint for your index, and modify the item heigh there

[proper jetty]

Hey, when using tksheet I display my data and want checkboxes above the data.

For i in cols:
    s.create_header_checkbox(c=i)```
Works, but the documentation states this can be set with a single "all" statement. I didn't get it to work, any advice?

[mighty frigate]

@sleek hollowyup, the stylesheet way just works:

from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
import typing
import sys

class Model(QAbstractListModel):
    def __init__(self, datas, parent = None) -> None:
        self.datas = datas
        super().__init__(parent)

    def rowCount(self, parent: QModelIndex = ...) -> int:
        return len(self.datas)

    def data(self, index: QModelIndex, role: int = ...) -> typing.Any:
        if index.isValid() and role == Qt.DisplayRole:
            return str(self.datas[index.row()])

app = QApplication(sys.argv)

listview =  QListView()
model = Model(range(0, 10))
listview.setModel(model)
listview.setStyleSheet("QListView::item { height: 50px; }")

mainwindow = QMainWindow()
mainwindow.setCentralWidget(listview)
mainwindow.show()

app.exec_()

Also it appears that I was wrong about what I told you yesterday : you do need to store your own checkstate datas, Qt won't do taht for you

a working example of checkable string list model :

class Model(QStringListModel):
    def __init__(self, datas, parent = None) -> None:
        self.datas = datas
        self.checkdatas = [False for _ in datas]
        super().__init__(parent)

    def flags(self, index: QModelIndex) -> Qt.ItemFlags:
        default_flags = super().flags(index)
        default_flags &= ~Qt.ItemIsEditable
        return default_flags | Qt.ItemIsUserCheckable

    def rowCount(self, parent: QModelIndex = ...) -> int:
        return len(self.datas)

    def data(self, index: QModelIndex, role: int = ...) -> typing.Any:
        if not index.isValid():
            return None            
        if role == Qt.DisplayRole:
            return str(self.datas[index.row()])
        if role == Qt.CheckStateRole:
            return Qt.CheckState.Checked if self.checkdatas[index.row()] else Qt.CheckState.Unchecked
        return super().data(index, role)

    def setData(self, index: QModelIndex, value: typing.Any, role: int = ...) -> bool:
        if not index.isValid():
            return False
        if role == Qt.CheckStateRole:
            self.checkdatas[index.row()] = True if value == Qt.CheckState.Checked else False  
            return True
        return False

[swift mountain]

I don't get it...does PyQt5 have anything like "gui" in its library that pyqt6 does not have?

[mighty frigate]

... You already imported QtGui, what more do you want

[swift mountain]

or is it a whole different library idk i am kinda new to interfaces

[mighty frigate]

@swift mountainwhat are you looking for exactly

Qt never had a gui library afaik, it does have a QtGui library tho.

[uncut oar]

I'm building a command line tool with argparse and the documentation for the actions keyword arg to add_argument (https://docs.python.org/3/library/argparse.html#action) strikes me as weird. What's the use case for action='store_true' and action='store_false' when default=True and default=False does the same thing?

[sudden coral]

Setting a default doesn't do the same thing, because it would still allow the user to override the value. I'd equate action='store_true' to action='store_const', const=True instead. I'd guess it just exists as a shorthand for a common use case.

[charred oracle]

https://paste.pythondiscord.com/asafunotet - why does this example have a text box, why doesn't the text go into the active application, how I make that happen. I want the on-screen keyboard at the bottom and a much larger place to enter text at the top. Not just the text box but a whole area at the top of the screen where you can enter text. This is an example I copied from someone's github. Also, I want to use pysimplegui to change the color from blue to pink, where would I put the hex color codes for each element of the keyboard?
also why does it use something called Elvis in the code?

[devout galleon]

Hey there, I've created a version of Conway's game of life (with classes), using matplotlib. So I have a bunch of buttons, interactivity with the plot, etc. And I want to use TKinter to create a user interface and allow anyone to run the game as an exe.

[lament rampart]

Hello, I have a problem with pyqt5 with multithreading when I am creating a new thread to do some background calculations after a button click this newly created thread is not being destroyed after the end of the function and when I am clicking again the button another thread is created on top of the previous one. Short example: Initially -->MainThread, first click of a button--> MainThread, DummyThread-1, second click of a button--> MainThread, DummyThread-1, DummyThread-2 .... . I know I have to use Signals(pyqtsignal), but I dont know exactly how to use them. Can anyone give me some tips on how to signal the stop of the thread after the end of the function. I tried to follow this tutorial(https://realpython.com/python-pyqt-qthread/) but the finished.emit() signal is not being emitted.

[mighty frigate]

wait wait wait

@lament rampart let's take the problems one by one

[lament rampart]

ok

[mighty frigate]

what are you using to create and start your thread

there's a few different way to do it wih Qt

[lament rampart]

Ok, I have this line of code that triggers a POS_accept_request function. self.Entry_button_PayPod.clicked.connect(self.POS_accept_request)

POS_accept_request function is this:

[mighty frigate]

are you subclassing QObject and moving it to a QThread ? Are you subclassign QThread ? Are you using QRunnable and QThreadPool ?

QObject and QThread ok

[lament rampart]

yeah right Qobject and qthread

[mighty frigate]

show me Worker pls

[lament rampart]

one moment

Worker class is too big its start is like this:

[mighty frigate]

idc about the urn function

[lament rampart]

my bad

[mighty frigate]

I just want the signal definition and the emit

np

[lament rampart]

I am initiliazing the finished variable with a pyqtSignal

[mighty frigate]

looks fine

what about the emit ?

[lament rampart]

ok, emit is located inside this bug run function in several points. One point is this one: (Give me a moment)

[mighty frigate]

ok I trust you

[mighty frigate]

when you run your code in debug mode, is there anything showing in the console like "cannot connect signal" blablabla ?

[lament rampart]

No, the code runs fine. The problem is that the created threads in the end of the function are not being deleted.

[mighty frigate]

we'll see about that

add

def __del__(self):
        print("--- Worker destroyed")

in your worker class

and tell me if the message is printing

[lament rampart]

no the message is not printing

[mighty frigate]

are you in a run mode where messages actually get printed usualy ?

[lament rampart]

Yes I am in run mode. These are the messages

[mighty frigate]

are you sure the signal is actually emitted

like, can you put breakpoints on every emits of finishe and check if you actually run on it

[lament rampart]

Ok, before doing that, I have a question. I assigned my thread to the self.pay_thread_1 variable. When I am running self.pay_thread_1.isRunning() is printed False, which means that the thread is not running. But When I am threading.enumerate() (that function creates a list with the active threads) the dummy thread is alive how is that possible?

[mighty frigate]

it may be because you didn't start the thread yet, or it is finished already

threading.enumerate() doesn't ring a bell, I'll have to check the documentation

[lament rampart]

I have checked the documentation where it says that:

[mighty frigate]

oh this is a python function

[lament rampart]

Yeah.

[mighty frigate]

I wouldn't trust it too much

like, Qt likes doing its own thing

I wouldn't be suprised if Qt kept that thread alive behind the scene because Qt reasons

[lament rampart]

Ok. I can see your point.

[mighty frigate]

in that regard I have more faith in QThread::isRunning

[lament rampart]

Yeah, but wont I have in the future a problem with the memory if too many threads are created?

[mighty frigate]

I can make you a working example of Worker/QObject with a correct finished emitting

maybe you can use that to compare to your own thing and see what's going wrong ?

I mean, if the finished signal isn't emitted, it's perfectly normal that the thread isn't destroyed

that's where the problem is

[lament rampart]

Ok, I will try now your proposition of using breakpoints at every self.finished.emit() to see if the signal is emitted. I really appreciate your help @mighty frigate. Message me If I can do something for you in the future.

[mighty frigate]

np

that's one of the only thing I can do ok-ish

oh also, I noticed you maybe forgot to connect to destroyLater of the QThread when the worker is finished

you might want to do that

or maybe you're doing it somewhere else idk, but still

[lament rampart]

Let me check that, but I just checked the signal is indeed emitted. So maybe this is the problem.

[mighty frigate]

I don't think it is

because the worker isn't destroyed

it should, as you've connected the finished signal to the worker deleteLater func

[mighty frigate]

but we're going somewhere, the signal is emitted but isn't received somehow

[lament rampart]

Ok, this is the piece of code, the first line what it does when the worker finishes quit the thread

[lament rampart]

Ok, so I have to check if the signal is received where I want. Understand.

[mighty frigate]

afaik quitting a thread doesn't destroy it

anyway that's not the main problem for now

what does exit_UI do ?

I'll rephrase

you have a QApplication somewhere

does exit_UI destroys that QApplication ?

[lament rampart]

exit_UI is a function where I am modifying a widget.

[mighty frigate]

ok

[lament rampart]

self.w is the widget

[mighty frigate]

it's fine then

[lament rampart]

This function is running btw

[mighty frigate]

destroying the QApplication might explain why it's not working because QApplication is reponsible of the event loop. If you destroy the event loop, there's no signal/slot anymore. well afaik.

so plan B it is

[lament rampart]

One moment I want to understand this clearly.

[spark tinsel]

@mighty frigate @lament rampart can you help a noob? How can I nest tabs inside pages in pyqt? After you finish your problem ofc, I can wait. 🙂

[lament rampart]

I have one question and I wont spend any more time. The event loop if the run function in the Worker class?

[mighty frigate]

don't bother with the event loop. If you have a QApplication and you're not destroying it, you're fine

[lament rampart]

Ok. I appreciate once more the help. Dont hesitate if you need something. Thanks a lot!

there's indeed some weird things in the python Qt API

like, the worker deleteLater signal is never actually called for some reason

but the underlying C++ wrapped object is correctly deleted tho

I'm not sure I understand wth is going on, but this example does work

there's also some dummy threads showing in vscode but I think it's more incompatibility between threading and Qt than a real problem

[hollow stump]

That's the thing I can't seem to find how to use it in my case

I try to call the figure object from my class Conway and then use the TkAgg on that but it doesn't work

[lament rampart]

Ok, so your opinion is that the thread is actually deleted or no?

I ran your code and I figured out something interesting indeed the threading was deleted everytime run button is pressed, but when I put a breakpoint this happened.

I just added to your code self.thread.destroyed.connect(self.enumerate) and I put a breakpoint at enumerate function and then the threading was not being deleted.

[mighty frigate]

I'm confident that the thread and the worker are deleted, but I really don't understand why the worker destroyed signal isn't triggered and why threading think there's still threads pending

[hollow stump]

(https://github.com/ChrisZeThird/Game-Of-Life/tree/main/ObjectOriented source code)

I'm asking once again

because I can't figure this out

setting the buttons and connecting the functions doesn't seem complicated but I don't see how to make it work

[hollow stump]

I just don't understand how to insert my matploltib figure inside a tkinter window. I've searched online, found several answers from different posts, but I don't see how to apply those solution to my problem, especially because I created classes. Can I create the root window outside the class or should I create it in the init of my classes. I kinda see how to add the buttons, and connect them to my different functions, but what about the animation? Creating buttons resulted in an embedded plot in tkinter, an empty matplotlib window being displayed and a non working animation (only the plot interactivity when you click on a cell works).
I've tried adding the root window to the class, using canvas and FigureCanvasTkAgg. This places the figure inside the tkinter window but it isn't animated anymore.

Class Versus():
  def __init__(self,N):
    ...
    self.root = init_figure.root
    self.root.title("Conway's Game of Life - by ChrisZeThird" )
    self.root.geometry("1080x720")
    self.fig = init_figure.fig
    self.ax = init_figure.ax
    self.fig.suptitle(f'Each player has {self.nbr} cells to place', fontsize=20)
        
    self.canvas = FigureCanvasTkAgg(self.fig, self.root)
    ...
    ## I translated matplotlib buttons to tkinter buttons
    ...
    self.canvas.get_tk_widget().pack(fill="both", expand=True)

and later on I have self.canvas.mpl_connect('button_press_event', self.turn_on) # connect cells management to figure. I also removed the event variable in the button commands and remove the button axes and definition to replace them with tkinter button.

I tried doing it externally to the class. So I made another file and called the class there.

versus = cv.Versus(N)
fig = versus.fig
# Creating Canvas
canv = FigureCanvasTkAgg(fig, master = root)
canv.draw()

get_widz = canv.get_tk_widget()
get_widz.pack()

And that generated a separated figure, so not embedded.

You can do this with tkinter

Afaik you can even make the edges rounded

[unborn gale]

how would I make the shape without making a window?

[somber hemlock]

Idk about rounded, but tk.Tk has an attribute for that non bordered

Search on google, there will be stackoverflow results

[unborn gale]

do i just look up "tkinter shape without seperate window" or something? what i am looking up is not showing anything

[somber hemlock]

Search tkinter borderless window

Then search tkinter rounder window

Or search the second directly

@somber hemlock why is it so big

smh

Can't really notice it with your black IDE theme going on

i need to make it smaller, and it looks rigid

oh yeah so how would i center it?

[somber hemlock]

Well you can make it as small as you want can't you

[unborn gale]

the rounded thing is made with length and width

[somber hemlock]

Grab the screen coords and offset your widgets controls by those amounts

[unborn gale]

why the sides doingf that 😭

I'm using pyqt6 and wanted to know how to make a QStackedWidget resize to fit the content of the currently displayed widget exactly

[pliant pike]

Nothing I do seems to be working..

[thick apex]

Please, help
PyQt5, how do scrollable list/table kind of [image text]

like on youtube

[mighty frigate]

@thick apex QTableWidget is the simplest

probably best to use model/view with QTableView tho but it's more advanced

@pliant pike did you try QWidget.adjustSize() ?

worst case scenario you can use on of the resize function (setMinimumSize, setFixedSize, setMaximumSize) of QStackedWidget with your content sizeHint()

[thick apex]

I'm seriously a newbie and don't know much about sizing in PyQt5

Its possible to push on elements in table, not like cells, but like on whole lines

[mighty frigate]

you're the one in control. What's stopping you from creating a function that insert your whole line cell by cell

[thick apex]

not insert

i mean selecting, like pushing on element(line) and

[mighty frigate]

also if you're handling a list and not a table, you should consider using QListWidget instead

selecting whole line ?

I believe there's a selection policy for that but I'll have to double check

@thick apex https://doc.qt.io/qt-6/qabstractitemview.html#SelectionBehavior-enum

to use with the setSelectionBehavior ofc

[thick apex]

its on table widget too?

[mighty frigate]

yes. see: https://doc.qt.io/qt-6/qtablewidget-members.html

@thick apex

even if the official documentation is in C++ I strongly advice you to go and read it, and search things in it. It can answer most of your questions.

[thick apex]

how to block changing elements text (content) in a table in QTableWidget?

[plain cliff]

Is it good?

[somber hemlock]

Why do you have a button for clearing fields?

The sign up button should be at the middle

Because that's the main action on that page

Could adjust margins more ig it looks super packed

[plain cliff]

To delete the values on entry

[plain cliff]

Alright thanks

[plain cliff]

Well i am going to add more buttons

[somber hemlock]

There's no need to put it. If somebody does an error they can clear a field by backspacing as well right?

[somber hemlock]

You can add a scrollbar then, don't try to fit it all in a single screen

[spark tinsel]

Is there a widget in PyQt to just add a wall of text (non - interactive)? QLabel is only 120 char long, I need something bigger if there is one.

[spark tinsel]

Or is there a way to expand QLabel somehow?

[thick apex]

how to make the column width stretch to the borders of the QTableWidget widget?

type of maximum width stretching. I don't have any ideas

[thick apex]

How do Signal for Entire Row Selection in QTableWidget in python pyqt5?

like this https://stackoverflow.com/questions/3144418/signal-for-entire-row-selection-in-qtablewidget

?

[spring saddle]

Can anyone help me with aligning "Single" with the other options?
its made w tkinter python

this is the coding

a =StringVar()
a1 =StringVar()

label = Label(window, text= 'Sex:').grid()

c = Checkbutton(window, text= "Male", variable= a)
c.deselect()
c.grid(row=0, column=2)

c1 = Checkbutton(window, text= "Female", variable= a1)
c1.deselect()
c1.grid(row=0, column=3)

label = Label(window, text= 'Marital Status:').grid()

MaritalStatusList=['Single', 'Married', 'Complicated', 'Divorced']
checkboxes={}
def ShowCheckBoxes(MaritalStatusList):
    Cbcolumn = 0
    Cbrow = 2

    for Checkbox in range(len(MaritalStatusList)):
        name = MaritalStatusList[Checkbox]
        current_var = IntVar()
        current_box = Checkbutton(window, text=name, variable=current_var)
        current_box.var = current_var
        current_box.grid(row=Cbrow, column=Cbcolumn)
        checkboxes[current_box] = name  # so checkbutton object is the key and value is string
        if Cbcolumn == 0:
            Cbcolumn =2
            Cbrow += 1
        else:
            Cbcolumn = 2
            Cbrow+= 1

ShowCheckBoxes(MaritalStatusList)

[eager abyss]

Instead of your if/else statement at the bottom, you can simply do Cbrow += 1
and then Cbcolumn should be 2 when you initialize it if you want it to line up in the center rather than underneath the Marital Status label.

[fringe coral]

anyone that can help me with a stopwatch function inside qt designer?

[mild whale]

Check in flag: "horizontalHeaderStretchLastSection" in header section

[fringe coral]

it only counts to 0.1 then stops, my conclusion is that it only runs once instead of getting updated, problem is I don't know how to fix it

here's the code

https://paste.pythondiscord.com/xobixomupu

[thick apex]

im go to try it

How set...HeaderItem(QHeaderView)?

its possible?

In QTableWidget

I can't figure out how to do it right

[fringe coral]

how do I stop this from resetting its size everytime something changes in the designer

it's qtextedit

[spark tinsel]

You haven't created a signal for when the timer starts, here's an example timer I've found online:
https://linuxhint.com/use-pyqt-qtimer/
You need to assign "False" as initial value to the flag and also set "self.timer.setSingleShot" to False. The way it is now it's like it's saying, if True and just loops forever. I think those two are the issues. I'm a beginner so not sure but it may fix this.

[fringe coral]

thanks, also, would you happen to know why

    @Slot()
    def submit(self):
        self.thread_manager.start(self.submit)
        print("Submitted")

which is attached to a .clicked.connect

gets run continously when I click it once, just starts spamming prints in the console forever

thread_manager is just self.thread_manager = QThreadPool()

[spark tinsel]

Sorry idk about threads yet.

[fringe coral]

I figured it out

[mild whale]

Are you not able to find that flag in header section??

[mild whale]

Tick that checkbox

[queen trout]

is there a way to increase the width of this white line in pyqt, these are 2 styled QPlainTextEdit widgets side by side

[vague parcel]

Qt using https://doc.qt.io/qt-6/qgraphicsview.html

try using custom tkinter

[prime prawn]

you know any good fork of tkinter?

[fringe coral]

yeah, it's called custom tkinter

[prime prawn]

oh sorry lol, didnt think that actually was the name. thx :) il try it out

[somber hemlock]

Qt is used by a lot of such detailed complicated apps, like IDA for example

[thick apex]

I want Stretch and Interactive selection resize modes in one time :

table = QWidgetTable()
table.setColumnCount(2) 
header = table.horizontalHeader()
header.setSectionResizeMode(0, QHeaderView.Stretch)
header.setSectionResizeMode(0, QHeaderView.Interactive)

[thick apex]

how i can do this?

[mighty frigate]

@thick apex the documentation says both modes can't work together :
https://doc.qt.io/qt-6/qheaderview.html#ResizeMode-enum

[thick apex]

If I want to resize it

With mouse

Mb other Way?

[mighty frigate]

please give me something I can run

preferably short

[thick apex]

Ok

@mighty frigate

import sys
from PyQt5.QtWidgets import (
    QWidget,
    QApplication,
    QGridLayout,
    QTableWidget,
    QHeaderView,
)


class W(QWidget):
    def __init__(self):
        super().__init__()
        self.resize(600, 400)
        layout = QGridLayout()
        self.setLayout(layout)
        table = QTableWidget()
        layout.addWidget(table)
        table.setColumnCount(3)
        table.setRowCount(4)
        header = table.horizontalHeader()
        header.setSectionResizeMode(0, QHeaderView.Stretch)
        header.setSectionResizeMode(1, QHeaderView.Stretch)
        header.setSectionResizeMode(2, QHeaderView.Stretch)


if __name__ == "__main__":
    app = QApplication(sys.argv)
    w = W()
    w.show()
    sys.exit(app.exec_())

i want column headers first: to stretch
second: to resize with mouse like by default

[mighty frigate]

how about

import sys
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *

class W(QWidget):
    def __init__(self):
        super().__init__()
        self.resize(600, 400)
        layout = QGridLayout()
        self.setLayout(layout)
        table = QTableWidget()
        layout.addWidget(table)
        table.setColumnCount(3)
        table.setRowCount(4)
        header = table.horizontalHeader()
        header.setSectionResizeMode(0, QHeaderView.Interactive)
        header.setSectionResizeMode(1, QHeaderView.Interactive)
        header.setSectionResizeMode(2, QHeaderView.Interactive)
        header.setStretchLastSection(True)

if __name__ == "__main__":
    app = QApplication(sys.argv)
    w = W()
    w.show()
    sys.exit(app.exec_())

[thick apex]

This only last section

[mighty frigate]

so you want the same behavior but not for the last section; only for the first one

correct ?

[thick apex]

For all

[thick apex]

by default the columns are NOT stretched evenly to the QTableWidget borders, but they can be resized with the mouse?

I want columns to stratch and after enable to mouse resizing

@mighty frigate I have only stretch, how do resizng after?

[mighty frigate]

you know I won't work any faster the more you ping me.

give me a minute

[thick apex]

I just asked, I think there may not really be an answer, so don't think I'm rushing you, I'm sorry

[mighty frigate]

my food just arrived I have to go

this is where I am

import sys
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *

class W(QWidget):
    def __init__(self):
        super().__init__()
        self.resize(600, 400)
        layout = QGridLayout()
        self.setLayout(layout)
        self.table = QTableWidget()
        layout.addWidget(self.table)
        self.table.setColumnCount(3)
        self.table.setRowCount(4)
        header = self.table.horizontalHeader()
        header.setSectionResizeMode(0, QHeaderView.Interactive)
        header.setSectionResizeMode(1, QHeaderView.Interactive)
        header.setSectionResizeMode(2, QHeaderView.Interactive)

    def showEvent(self, a0: QShowEvent) -> None:
        ret = super().showEvent(a0)

        v_header = self.table.verticalHeader()
        default_col_width = (self.size().width() - v_header.size().width())/3 - 8 # 8: some borders somewhere ? contentMargins ? needs to investigate
        
        h_header = self.table.horizontalHeader()
        h_header.resizeSection(0, int(default_col_width))
        h_header.resizeSection(1, int(default_col_width))
        h_header.resizeSection(2, int(default_col_width))

        return ret

if __name__ == "__main__":
    app = QApplication(sys.argv)
    w = W()
    w.show()
    sys.exit(app.exec_())

it's working but it's not perfect, it needs more time

[thick apex]

time is money

it is possible to make the rightmost edge of the header attached to the right side of the widget?

[winged solar]

First time using PyQt5 (or any Python GUI framework for that matter) and I can't figure out how to make it so my window updates after every frame. I tried it with calling .update() but that doesn't work. I tried it with .hide(); .show() which actually closed and reopened the window but still didn't actually draw anything. I tried .repaint() but that too didn't work.

Because my actual code would be unnecessary complex I came up with this minimal reproducible example.
When I comment out the loop method it actually shows me the paper at 100, 100 but whenever I let loop execute it just "crashes" and even after the code finished it still doesn't show me anything.

import sys
import time

from PyQt5.QtGui import QPixmap
from PyQt5.QtWidgets import QApplication, QMainWindow, QLabel

PAPER_IMG = "paper.png"
WIDTH, HEIGHT = 500, 500


def loop(win, elem):
    """This example method just drags a paper across the screen"""
    x, y = 0, 0
    frame = 0
    while x < WIDTH - 15 and y < HEIGHT - 15:  # arbitrary end condition
        time.sleep(1)  # arbitrary sleep (simulates a framerate in actual code)
        print(f"Frame {frame:03}")  # just to see that something is actually happening
        elem.setGeometry(x, y, 15, 15)

        win.update()

        x += 10
        y += 10
        frame += 1


def example():
    # Boilerplate PyQt5 code
    app = QApplication(sys.argv)
    win = QMainWindow()
    win.setGeometry((1920 - WIDTH) // 2, (1080 - HEIGHT) // 2, WIDTH, HEIGHT)  # centralized on a 1920x1080 screen

    # Add an image to the canvas
    elem = QLabel(win)
    elem.setPixmap(QPixmap(PAPER_IMG))
    elem.setGeometry(100, 100, 15, 15)

    # initial draw and loop
    win.show()
    # loop(win, elem)

    sys.exit(app.exec_())


if __name__ == '__main__':
    example()

Also the paper.png file in case you want to test-run it yourself (It's a custom 15x15 pixel art, hence the size of 15)

So yeah, question is: How can I repaint/update after every frame?

[mighty frigate]

@winged solar can you explains to me what it is you're trying to do ?

in 99.9% of the scenarios you want to let Qt do his thing and update the widgets itself

[winged solar]

In the code snippet provided: Move a paper across the screen.
In my actual problem: Simulate rocks, papers and scissors like in this video: https://youtube.com/shorts/D86dl1Hc5uI?feature=share

Can't remove embeds on mobile right now

[mighty frigate]

ok so you're actually in the 0.1% that needs to have some kind of control over the update

did you figure out how you're going to display the content yet ?

are you going to draw it all yourself, or are you going to create widgets

oh the answer is in the snippet, you're going to have widgets

[winged solar]

I have a class Element where each Element has a QLabel with a pixmap set to one of the pixel arts.

Element provides functionality to update movement, do collision checks, generate start values for all elements, etc

[mighty frigate]

give me a minute

[winged solar]

The snippet is actually really close to my actual code, just a tad simpler

[mighty frigate]

something like this

import sys
import time
import typing

from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *

PAPER_IMG = "paper.png"
WIDTH, HEIGHT = 500, 500

class MainWindow(QMainWindow):
    def __init__(self, parent: typing.Optional[QWidget] = None, flags: typing.Union[Qt.WindowFlags, Qt.WindowType] = Qt.WindowFlags()) -> None:
        super().__init__(parent, flags)
        
        self.frame = 0
        self.x = 0 
        self.y = 0

        self.elem = QLabel(self)
        self.elem.setStyleSheet("background: black;")
        self.elem.setGeometry(100, 100, 15, 15)
        self.elem.show()

        self.timer = QTimer()
        self.timer.setInterval(1000/30) # 30 movement updates per second
        self.timer.timeout.connect(self.updateElement)

    def updateElement(self):
        self.x += 10
        self.y += 10
        self.frame += 1
        self.elem.setGeometry(self.x, self.y, 15, 15)

    def showEvent(self, a0: QShowEvent) -> None:
        self.x = 0 
        self.y = 0
        self.frame = 0
        self.timer.start()
        return super().showEvent(a0)

def example():
    # Boilerplate PyQt5 code
    app = QApplication(sys.argv)
    win = MainWindow()
    win.setGeometry((1920 - WIDTH) // 2, (1080 - HEIGHT) // 2, WIDTH, HEIGHT)  # centralized on a 1920x1080 screen

    # initial draw and loop
    win.show()

    sys.exit(app.exec_())

@winged solar

[winged solar]

Thank you, I'll look at it after taking a nap. Trying to fall asleep with a prostate infection is quiet tedious though.

[mighty frigate]

ow well, good luck and good nap

[winged solar]

Kind of a longer nap, but at least now I'm fully awake.
The code you sent appears to be producing exactly what I was looking for. I'll look into how it actually works. Thank you so much.

[mighty frigate]

np

@winged solar if you're new to Qt, you def should take a look at the signal/slots feature

[winged solar]

Beg your pardon?

Where can I find that?

[mighty frigate]

in the official Qt documentation

https://doc.qt.io/qt-6/signalsandslots.html

[winged solar]

aight, thank you

But that's for PyQt6

[mighty frigate]

the official documentation is in C++, but it doesn't change much. The Qt API is the exact same in python and C++

oh right

[winged solar]

Do I need the Qt 5.15 LTS?

[mighty frigate]

https://doc.qt.io/qt-5/signalsandslots.html

[winged solar]

okay, yes. I needed the Qt 5.15 LTS

Just one more thing, the documentation seems to use C++.
Is this also relevant for Python?

Is PyQt5 just a wrapper for Qt5?

[mighty frigate]

yes

well that's not completly correct to says that

but for all purpose you can considere it is

afaik PyQt is not really Qt but some other company, while PySide is actually done by Qt

[winged solar]

okay, I'll just go with that x)

[mighty frigate]

but afaik both are just wrappers around the Qt C++ libs

and the official C++ Qt documentation is way more complete than any Qt Python doc you may find

[winged solar]

got it, thanks

[restive umbra]

hi guys, i want to make a good looking gui app with python.. can anyone suggest the best libs for gui in py please ?
i dont know with what i'm supposed to continue with, either tkinter or pyqt or anything else 😬

[rare crater]

both are sufficient for normal stuff
what did you have in mind?

[somber hemlock]

You don't need the ltest

Concepts remain the same

[somber hemlock]

Not a lot

Qt is fairly stable to break too much API

But that's what release notes are for

[coarse mirage]

hey i want to know that can we make the button in tkinter function only once no matter how many times we click it shouldn't execute the respective command

[somber hemlock]

You can disable and enable the button by using btn.config(state="disabled") or use a bool variable inside button's callback to store its state

Does adding gif animations cause significant overhead? I'm working with PyQt5 right now, and im thinking of adding animations for changing button states, but I wanted to know if there is too much of a performance hit for it to be worth it. Has anyone done anything like this before?

[bold roost]

does anyone know using textual, how to make it autoscroll?

[mighty frigate]

@chilly needle best is to try for yourself

ofc there's an overhead, there's always an overhead, but for most app it's insignificant

[vast radish]

Whats the best option to use out of tkinter, pyqt5 or flet. I just need to make a simple light ui that doesnt rely on anythign except python and can run entirely offline

ik a bit of tkinter and i love it, just that it's ui is out of date

Ping me when you have a response pls

[mighty frigate]

@vast radish I only use Qt so I wouldn't know, but I can tell you Qt is definitively the most complete of the 3

[vast radish]

is it hard to use

[mighty frigate]

arguably yes

[vast radish]

tkinter is very simple to make a basic ui and get it going

[vast radish]

any good tutorial (preferably text based)

[mighty frigate]

are you the kind of guy that reads documentation ?

[vast radish]

not really, that stuff confuses me

[mighty frigate]

well you'll probably struggle then

[vast radish]

unless it is written really well so that it is easy to understand

i learnt tkinter from a book lol

[mighty frigate]

there's some key concept you need to know and understand when you work with Qt. Iguess it's true for all libraries tho

[vast radish]

whats the qt docs?

[mighty frigate]

best advice I can give you : the official Qt documentation (in C++) is very nice

use it

[vast radish]

ahh ok

i do a little coding in c

mostly c#

but python is my main coding language

[mighty frigate]

tbh it doesn't really matter, the API is the exact same in C++ and Python

[vast radish]

ahh ok

[mighty frigate]

the syntaxe is a bit different but it doesn't change anything

[vast radish]

is pyqt web based?

[mighty frigate]

nop

https://doc.qt.io/qt-6/signalsandslots.html

one of the key concept we were talking about

[vast radish]

i need to be able to run it as an exe that can be downloaded very quickly

[mighty frigate]

well I guess that's on you

[vast radish]

so a signal is the start and the slot is the destination

[mighty frigate]

yessir

[vast radish]

yeah, thats how i build it

[mighty frigate]

exactly

[vast radish]

can i download qt with pip or is it a standalone app

[mighty frigate]

both

with python you can use pip

in Cpp you actually have to download Qt yourself

[vast radish]

ahhh

i love coding on a mechanical keyboard, Clickety clack all the time

[vast radish]

any docs specific to python version. id like to have a read of them too

[fervent onyx]

I want to make a simple gui app for a project i've made so that anyone can use it. The app just needs to ask for the input, activate the virtual env and run the code. How can i do this?

[vast radish]

virtual env's ewww

ahah jk

[fervent onyx]

Hmm is something wrong

[vast radish]

ahaha, no. i just don't use virtual env's

Activate the virtual environment
Before you can use this virtual environment, you need to explicitly activate it. Activation makes the virtual environment the default Python interpreter for the duration of a shell session.

You’ll need to use different syntax for activating the virtual environment depending on which operating system and command shell you’re using.

On Unix or MacOS, using the bash shell: source /path/to/venv/bin/activate
On Unix or MacOS, using the csh shell: source /path/to/venv/bin/activate.csh
On Unix or MacOS, using the fish shell: source /path/to/venv/bin/activate.fish
On Windows using the Command Prompt: path\to\venv\Scripts\activate.bat
On Windows using PowerShell: path\to\venv\Scripts\Activate.ps1
Note that the activated environment only works for the context it was activated in. For instance, if you launch two instances of PowerShell, A and B, and you only activate the virtual environment in instance A, that environment will only apply to A. It wouldn’t apply anywhere else.

Many Python IDEs automatically detect and activate a virtual environment if one is found in the current project directory. Microsoft Visual Studio Code, for instance, can do this when the Python extension is enabled. Opening a terminal inside Visual Studio Code will automatically activate the selected virtual environment.

Source: https://www.infoworld.com/article/3239675/virtualenv-and-venv-python-virtual-environments-explained.html

hope that helps, i am useless with virtual env's as i never use them

[fervent onyx]

Ok it worked without the virtual env as well😂

[vast radish]

yeah, i see no point to them unless you have conflicting libaries

they require you te set them up and install packages each time. Typical Aussie internet, alot of packages can take a hot minute

[vast radish]

I work on KISS (Keep It Simple Stupid), When making apps for people, design it for some one who does not know how to use a pc (not to dumbed down but)

[fervent onyx]

Is this a python library?

[vast radish]

i got bored the other day and made an api that can remotely start a game server. I need to refine it and add a UI to make the API calls

[mighty frigate]

I wouldn't know I only use the official one

[vast radish]

ahh ok

[vast radish]

KISS?

[fervent onyx]

Yeah

[vast radish]

No....... its a saying

[vast radish]

how old are you............

[fervent onyx]

Oh hahahahah

What do you use to make an app then

[vast radish]

i used to use tkinter but ima try my hand at pyqt

[mighty frigate]

Qt does a lot more than just UX too

[vast radish]

...... once i have finished this damn assignment

[vast radish]

what else?

[mighty frigate]

SQL, filesystem, web related things, networking, regex and a lot more

[vast radish]

networking, OoOoOoOo

[mighty frigate]

https://doc.qt.io/qt-5/modules-cpp.html

[vast radish]

my career is IT and im on the Networking side of it

any good tutorial?

[fervent onyx]

Can tkinter solve this?

[mighty frigate]

well in languages like C++ it's a good thing because you don't install a lot of dependancies usually

[vast radish]

are the modules available in python as well? cos having bluetooth seems useless but cool

[mighty frigate]

but that's not the case with python.

like, if you need to do some networking task, you can simply use request

for example

[vast radish]

i love that

may make building my api server start thingy a UI easier

[pine jewel]

What's the fastest or best gui to learn?

[digital rose]

tkinter is pretty simple

wouldnt say best

[somber hemlock]

Kivy is good

If you can deal with the fact that it has no type hints

[hoary swift]

Is there a gold standard of CLI format converter design that is worth using as reference when building a new one?

[hoary swift]

do you mean fastest when running, fastest when learning, or fastest to build with?

Also, best depends on your priorities:
Good mobile support means kivy,
Ships with Python means TKinter,
Works with anything that has a framebuffer is probably one of the dearimgui bindings,
Web support means using a web-specific frontend framework, etc

[somber hemlock]

Kivy is not good at mobile, its only supported

Best consider it an alpha for android or ios

Good morning, I am using QgridLayout in pyqt5 desktop app. I am wondering if it is possible to move a QLabel inside its cell.
I have this ui:

I would like to move the second row near the first row and the QLabel of the second be at center text of the first row.

[mighty frigate]

QLayout::addWidget can take an alignment as params iirc

check the QGridLayout documentation

Thank you that worked.

There are many graphical user interface (GUI) toolkits that you can use with the Python programming language. The big three are Tkinter, wxPython, and PyQt.

[shell lily]

(TKINTER) how does button placement work when button is placed on a frame? In my code buttons gets croped and the frame size doesnt change , no matter what i do.

[copper jackal]

How can I do closeEvent in PyQt5 without using QMessageBox (for the X button at the top of the window)

[sharp junco]

One more thing...is Django best framework for websites or the is another language better?

[copper jackal]

Please tag when you answer thank you

[static cove]

You would override the function within your subclass for the QMainWindow or QObject

[copper jackal]

how so

[copper jackal]

I'm using this but it doesn't work ```py
def closeEvent(self, event: QtGui.QCloseEvent):
print("Check")

[static cove]

class MainWindow(QMainWindow):
    def closeEvent(self, event):
        print("Trying to close this window")

main_window = MainWindow()

This is super slimmed down and non-functional, but that's how you'd do it

[copper jackal]

I really don't understand and I can't 😦 Would you look if I threw you open source codes?

[static cove]

Yeah, if you have code post it~

[proven basin]

Hey @copper jackal!

You either uploaded a .txt file or entered a message that was too long. Please use our paste bin instead.

[copper jackal]

https://paste.pythondiscord.com/muwububuva

[static cove]

So the issue is how you're constructing your classes. You want to catch the closeEvent from Form, but that's not something you're subclassing. Rather than creating a generic class Ui_Form that then takes a QWidget as an argument, just subclass QMainWindow directly

[copper jackal]

how do i change this

[static cove]

So I don't follow your code 100%, especially how you're passing around Form.
This code doesn't 100% function since I commented out some stuff, but hopefully it gets the point across.

You want to change your Ui_Form to be the main class and have it inherit from either QWidget directly or QMainWindow. You then want to change your code to build directly in this class instead of passing around Form

https://paste.pythondiscord.com/warunuqusu

[copper jackal]

but it did happen

[static cove]

What happened?

[copper jackal]

nothing loads and functions do not work

[static cove]

Right, like I said I did comment out a bunch of things and the code I have there is to show you that you can now catch the closeEvent event. I didn't change it over 100%, that's still up to you

[copper jackal]

both the widget defined above and below

[static cove]

I just called the other widget a temp name widget, you can change it to something else. But it's also different from self.widget

[copper jackal]

is it because of the variable of _translate that he didn't read this place?

not work 😦

[boreal halo]

Is Eel good for GUI development?

[hidden mirage]

I am very slowly building the internals for a system that would help a DM to run combat in a game of Dungeons and Dragons. It isn’t intended to be a virtual tabletop, it won’t handle maps or movement or anything like that. It’s just a tool to track initiative, hit points, actions, and so on.

Ideally it will eventually have an interactive interface for the DM, and a “read-only” interface for players (probably over the web?)

When I’m satisfied with the core logic, I will start adding API hooks, probably with FastAPI because I know it a bit.

What I don’t know yet is, what should the UI technology be for the DM? Ideally a user would have to do some setup in advance, but when playing they would just need to press a few keys. I’d love a hot key system, where the DM could do anything if they need to, but all the most common options are easy to see and easy to pick - ideally just a single keypress.

Can I use a modern TUI for that, at least for a prototype? Can you recommend one?

And for a final version, are there web tools that will allow me to focus on accepting keyboard input? I guess it would be some JS, right?

[hoary swift]

modern TUI
This had some hype around it a few months ago, but I haven't had a chance to use it yet. https://www.textualize.io/

Then you just draw a box and the rainbow color, something like rich is pretty good at that. Colorama if you just need simple stuff

any one could help me with this error?

[shell lily]

you need to add full path of the .ico file

[misty canopy]

I'm using pyside6. How can I do some job in a worker thread, then when it's done, modify something in the GUI in the main thread? I can't have the job itself do that; getting an error due to trying to add children to an element from another thread.

Do I need to use, like... some fancy Qt callback mechanism?

[eager beacon]

emit the result from the thread to a callback in the main

[misty canopy]

I'm currently doing this in the GUI thread:

text = self.links_inp.toPlainText()
parts = text.split()
failed = mildly_long_job(parts)
self.links_inp.setPlainText("\n".join(failed))

which works fine, but with a slight delay due to mildly_long_job.

[misty canopy]

hmm, interesting, lemme check how that works..

[eager beacon]

its fairly straight forward to do most of the time

threadSig.whatever.connect(self.mainthreacallback)
threadSig.emit(something)

Are you using a runnable or Qthread ?

[misty canopy]

I was trying to just submit a callable to a python threadpool

[eager beacon]

there is QThreadpool that works with with signal/slot and there are a bunch of good examples online

https://www.pythonguis.com/tutorials/multithreading-pyqt6-applications-qthreadpool/

Thats a nice write up on different methods available for threading and it has boilerplate examples to play with

QThreadPool is probably the most complex of the available options but its still easy enough to understand if you're familiar with how threadpools work in general

[misty canopy]

@eager beacon I ended up doing this, which works. How does this look?

class WorkerThread(QThread):
    result_ready = Signal(list)
    def run(self):
        failed = mildly_long_job(parts)
        self.result_ready.emit(failed)

def update_links(failed):
    self.links_inp.setPlainText("\n".join(failed))

text = self.links_inp.toPlainText()
parts = text.split()
thread = WorkerThread(self.app, self)
thread.result_ready.connect(update_links)
thread.finished.connect(thread.deleteLater)
thread.start()

[eager beacon]

That works as is?

[misty canopy]

It does.

[eager beacon]

Oh, yeah.. I guess it might. Are you using a worker object?

QObject subclass

[misty canopy]

I don't have any direct subclasses of QObject, no

[eager beacon]

That's usually the best way to go from what I understand though if you search enough you can find an old thread on the old Qt site saying that using QThread alone doesn't have to be a bad thing

[misty canopy]

I assume that's what's used in this horrible, probably autogenerated-from-C++-docs snippet

[eager beacon]

usually you set up a worker that has a callback that does the actual work. generally It's called using mythread.started.connect. When the worker callback is complete it emits the result to wherever you need it to go

yeah, i'd be surprised if that worked. you almost always have to use self.worker for self.worker.moveToThread things to work properly

[misty canopy]

It is important to remember that a QThread instance lives in the old thread that instantiated it, not in the new thread that calls run() . This means that all of QThread ‘s queued slots and invoked methods will execute in the old thread. Thus, a developer who wishes to invoke slots in the new thread must use the worker-object approach; new slots should not be implemented directly into a subclassed QThread .
I'm guessing it's because of this gotcha, but in my case that's actually exactly what I want, so the thread-subclass approach works.

[eager beacon]

nice when stuff just works out like that

[coarse prism]

Question, to call an interface in other file does it need to have classes and that kind of stuff?
this is the case:
I have two files, login and map, login is code with a class that basically gives you correct or incorrect depending the input(user and password), and map it is just the root window with a frame that contains a map with some functions(markers, paths in the streets, etc), and the thing is that I wanna write a condition in login that if the user log in then the map will open, so the question is, can I call something inmap that gives me the entire interface working?

let me know if code is necessary, I didn't send it because the interface's code is a bit disorganized, but tell me if it is necessary

For the ASCII art, you can use that generator, and for the coloring, perhaps you can use Blessed or just color each column individually

What do you think will be the next metaphor for UIs?

I've read that Gen Z see computers as "magic bags", and don't understand, nor follow, the idea of directory structures and "filing cabinets", just use the search bars to get what they need

I thought that was very interesting, and started noticing the analogical metaphors implied in all sort of software, and i think its a really interesting idea, one of a non-symbolic? iconic? (i never remember the terms of semiology) UI. To put an example, say art/image manipulation software, do we really need the concept of brushes and canvases when the people using it never used brushes or canvases? Do they think about image manipulation in that way?

Hey, I'm getting a visual bug with tkinter and tksheet.
I display a table and autosize it depending on the longest text in cells. This can cause a table to be 500px, in the next document maybe only 400px.

When displaying the new, narrower table it's placed visually above the old table and the remaining old 100px are still visible next to it. I can even scroll!

Is there any function to fully flush the page/frame? I tried

sheet.destroy

before but that didn't change it

[proper jetty]

oh well figured it out..
button now destroys the whole frame, via a function, then makes new frame, then new sheet. Couldn't call the .destroy in the same function, as then python throws an error that the variable fameFilter is referenced before initialization

def button_search():
    if randomCondition:
        frameFilter.destroy
        refresh_frameFilter()
        createSheet(data)

def refresh_frameFilter():
    global frameFilter
    frameFilter = customtkinter.CTkFrame(           
                    master=app,
                    corner_radius=15,
                    )
    frameFilter.grid(       
                    row=1,      
                    column=0,

Hi! How would you make such an animation in python? The animation is about showing the concept of time division multiplexing. Each user has data to send through the shared medium. Data from all users is combined into frames. Length of the frame is equal to number of users. When user has no data to send the slot remains empty

Here is another example: http://dccanimations.appspot.com/animations/tdm/animation.html
I think it's about moving squares from left to right

I just realized I get resolution problems on Laptop vs Desktop. Laptop has resolution scale set to 125% (16" display) and desktop is 100%.
My app looks well on the 125% setup and wrong on 100%. is there any way to easily fix it? i pass width and height in px to tkinter widgets and the window size.

first image is on laptop, second on desktop

[sleek hollow]

I've run into the exact same issue and it's a pain for sure! I've never gone as far as implementing a proper solution (I'm the only one using the tool), but you would need to get your monitor DPI and use it in some sort of ratio calculation for your widget sizes

I know how to get DPI with PyQt but not really sure with tkinter

[mighty frigate]

@sleek hollow that's the same kind of solution we have implemented in our product here too

but it's more like a quick fix than an actual solution honnestly. Best would be to do like most website do : have a set of target resolution, and reorganize the UI for each of those

[sleek hollow]

Yeah that seems way less head-achey!

[proper jetty]

Ok so it's not only me 😄 I found also a hacky solution.
On startup a window is created, set to full screen, save x&y, destroy window. Using those values I calculate the width& height for my usecase, works I guess

[mighty frigate]

sadly it doesn't work in all cases

[proper jetty]

One downside is this makes a small window flash up shortly.

[mighty frigate]

for example, you can customize the text size on windows

the resolution alone isn't a good enough indicator

[proper jetty]

Hm have to check that. As I mentioned I just realized this due to 100% vs125% scaling. Both monitors are 1080p bit the laptop looks so much different

[mighty frigate]

to solve the windows flashing, you could use another lib to get the screen size

[proper jetty]

Yeah probably easier. I found something on Stackexchange but I think that was for Linux. I'll look how to get the size, probably with some

os.getscreendimensions```
Or similar

There's some very nice answers on this topic on Stackoverflow. Let me see if I can find one.

[spring sinew]

Is it normal that when I use PyQt5 in VS Code, I get no autocompletion for methods like setCentralWidget or even any documentation describing what kind of parameters classes, functions and methods accept?

[ripe shuttle]

If you run into those kinds of problems, just check for plugins for the language/framework you are using. Popular ones almost always have a good plugin.

[somber hemlock]

Try this library. I suppose you have already installed Pylance, its like the most default thing VSCode does when you open a Python file

!pip PyQt5-stubs

[shell lily]

what do you guys think about this scrolling i added in my app?

[somber hemlock]

Considering tkinter has no animations, this is quite good 👍

[shell lily]

thx , i want to do this with 20 buttons , i dont think it will be as smooth as this after that

[somber hemlock]

Well this one looks smooth enough to me. But tkinter is entirely CPU rendered ig, so yea

Tkinter is quite bad perf-wise. You might have some better luck with canvas ig

[vivid dagger]

Hi, if I make an application in python using tkinter for my gui, will users have to manually install packages like tkinter and customtkinter? Or will the application just work for them out of the box.

[somber hemlock]

On linux you need to install tkinter separately

sudo apt install python3-tk

[shell lily]

If u r talking about making it like desktop app , u can do it with packege makers like , pyinstaller

[vivid dagger]

Yeah I want to make it into an installer.exe file that people download and then they can just use it. Just like any other software you download..

[shell lily]

Than use pyinstaller, u can install it through command prompt

Using pip

[vivid dagger]

Ok thx, and the user doesn't need pyinstaller to install my application right?

It will just be a setup.exe file that includes everything needed?

[shell lily]

Yes ,user can just use it as normal desktop app

[vivid dagger]

Ok thx man

[shell lily]

Gather all your necessary files in one folder
Than go to that directory in command prompt
Type : pyinstaller {main file of your app.py} --onefile --noconsole

[vivid dagger]

Thanks, yeah I'll be using customtkinter and I read that --onefile doesnt work with that instead it says to use --onedir

[swift mountain]

How to modify the UI after I've converted the .ui file into.py file...is there any way to modify it with Qt designer once it's converted to .py file?

[somber hemlock]

Just modify the .ui file and convert it to .py again

You can manually modify the code in .py file as well

[swift mountain]

Yeah but like I added lots of backend code into that file..so even if I edit the original .ui file and convert into .py again then I'll have to write the backend code all over again

[somber hemlock]

Backup the existing one, merge back the changes

You shouldn't even be touching the .py file created by qt, you are supposed to write your code in a different module

[swift mountain]

got it! thanks

Is there any way I can replicate that network activity graph in python? apart from matplotlib

[spring sinew]

Would you recommend using Qt Designer and loading .ui files when working with PyQt? That seems quite helpful initially but it feels like it would cause more issues down the road compared to just purely doing it via Python.

[mighty frigate]

@spring sinew Qt devs recommand using Qt Designer

I personnaly hate it and I don't use it

[spring sinew]

Is there any reasoning behind their recommendation and your hate?

[mighty frigate]

this is a litteral quote from a conversation I had a few months back with a dev from Qt

creating an UI manually is tedious and not error-proof 
unless you 100% understand the spacers, layouts, size policies let Designer do it for you. if you 100% understand 
2 situations:
* if you don't fully understand spacers, layout, size policies, ... → use QtDesigner.
* else → use QtDesigner

and I personnaly don't like it for 2 main reasons :

• I feel like I'm not in control of the generated code
• More often than not you need to customize the widgets you're using and you need to code it anyway

[rocky dragon]

I found it useful for prototyping how things should look, but other than that after maybe a week of using Qt it's faster to code manually anyway

[swift mountain]

Rather use tkinter tbh pyqt is meh

Like it's kinda messy when you need to modify your UI after converting to .py... with tkinter you know what you're doing because you're writing the code yourself instead of generating

[spring sinew]

Isn't that problem resolved by just not using Qt Designer and entirely writing it yourself?

[swift mountain]

Yeah then there's not much difference...but I guess people use pyqt for the designer

Also what I personally experienced is that PyQt has steep learning curve

I found tkinter less of a headache

[mighty frigate]

PyQt is, afaik, way more capable and has way more features than tkinter

it depends on your need I guess

[ebon bison]

Trying to update a label inside my app class from another class that inherites the app class, even declared it app=App() but it cant find the attribute label, what might I be doing wrong?

[mighty frigate]

you need to specify what lib you're using.

[ebon bison]

Sorry, tkinter + custom tkinter

[somber hemlock]

People use pyqt for real apps 😛

Those that already use qt for desktop apps would find pyqt easy

[mighty frigate]

^ can confirm that

it's the exact same

[short badger]

does anyone know where to find simple practical example of something made with tkinter (only the original modules no extensions or anything)

[sullen pendant]

Hi there, for some reason I'm struggling putting together a UI using Tkinter, I can't get the actual user input from text fields. Is there a more user friendly library than Tkinter?

[sleek hollow]

Can you share the code you've written that isn't working as expected?

[sleek hollow]

and tkinter is typically regarded as one of the more user friendly ones

just as I thought 😉

never .place() on the same line you assign your widget

[sleek hollow]

widget = Button().place()

widget = Button()
widget.place()

[sullen pendant]

Haha is that really the issue?

[sleek hollow]

yes, you've assigned widget to the return value of place() instead of Button() (as in my example)

and place() has no return

very common mistake

[sullen pendant]

Lol thats hilarious, thank you. I'll give that a shot

Thanks!

[sleek hollow]

it's ok to do this for widgets that you don't need to reference to later (like labels/buttons)

but anything you need to interact with again, you must separate it out like that

[sullen pendant]

Gotcha, I'll keep note of that. Thank you

@sleek hollow darn, no luck. Still getting "PY_VARX". Any other thoughts?

The text inputs lines are now of the form...

self.widget_input = tk.Entry(self, textvariable=self.var_name)
self.widget_input.place()

I've looked into using trace() as well, would that help here?

[sleek hollow]

depends what exactly and how exactly you're trying to do it

@sullen pendant Here's a super basic example of getting the text from an entry

import tkinter as tk 

def print_text():
    print(e.get())

root = tk.Tk()
root.geometry('200x50')
e = tk.Entry()
e.pack()
tk.Button(text='Press Me', command=print_text).pack()
root.mainloop()

Type something in the entry. When you press the button, it will print to console what text the entry has

[sullen pendant]

I haven't seen this pack(), maybe that's my issue?

[sleek hollow]

pack is just another way of adding something to the window

place and grid are the other ways

[sleek hollow]

What's the best way to approach filtering a model/view in PyQt? I have a class inheriting from QAbstractListModel, and it contains a list full of items from another custom class. Those objects have a bool attribute and I want a toggle to only display the ones with a True value. I tried using an if to only return the True objects but the False ones still show up (just without a display name or icon)

[sleek hollow]

Ended up using a buffer list to hold all the master objects and another to hold the filtered objects, and then I use that as my model. Not sure if this is the most efficient approach but it seems to get the job done for now

[young imp]

Wait what

You can make UI with Python?!!?

[vital dome]

Yeah. That's what I've been doing for the past 3 years

[mighty frigate]

@sleek hollow QSortFilterProxyModel does exacly that : https://doc.qt.io/qt-6/qsortfilterproxymodel.html

[earnest quest]

So I just started to create a UI and I'm planning to divide each section into classes to keep my code more organized. Here's what I have so far:

import tkinter as tk
from tkinter import ttk

class MainFrame(tk.Frame):
    def __init__(self, master):
        super().__init__(master)
        self.grid(row=0, column=0)

I'm planning to set the positions of widgets using grid inside the init method. If I want to position the main frame itself, I'd use self.grid(ARGUMENTS) but if I wanna position a widget inside that frame, I'd use self.widget.grid(ARGUMENTS).

---

The main problem I have here is the similarity of those two lines mentioned above. I'm afraid that it may confuse some people, since the main frame is positioned relative to its parent and the widget is positioned relative to the main frame. The lines also look very similar so I'm afraid that people may mistaken self.grid(ARGUMENTS) as positioning a widget instead of the main frame. As a result, I'm afraid my code will end up being a clutter of elements, some placed relative to the main frame and some placed relative to the parent of the main frame, with no way to find out which is placed relative to which. What should I do to fix this? Should I add comments to clear the confusion or is there a better way?

[somber hemlock]

You will call self.grid only once, I don't see an issue. You can also override the grid() method of MainFrame to separate the placement code from widget initialisation

[sleek hollow]

Not quite sure I follow how this is used. So how would I apply to my model to show only the objects that have a certain bool attribute as True?

[mighty frigate]

@sleek hollow so if you look at the presentation of the class, you'll see something like this :

model = MyModel(some_datas)
proxymodel = MyProxyModel()
proxymodel.setSourceModel(model)
myview.setModel(proxymodel)

As you can see, proxy models are models that wrap other models

@sleek hollow they provide some usefull builtin features that you can customise, like sorting and filtering

for filtering, proxymodels have a method that you need to overwride :

class MyProxyModel(QSortProxyModel):
    def filterAcceptsRow(self, sourceRow: int, sourceParent: QModelIndex) -> bool:
        return True if something else False

(this is an example for the rows, there's a similar functions for columns)

Applied to your case :

class MyProxyModel(QSortProxyModel):
    def filterAcceptsRow(self, sourceRow: int, sourceParent: QModelIndex) -> bool:        
        source_index = sourceModel()->index(source_row, self.filterKeyColumn(), source_parent);
        return source_index.data(MyCustomRoleForMyInternalBoolData).toBool()

This is untested and ported from C++, this might not be exactly correct but you get the idea

[spring sinew]

I am reading a book about PyQt and came across this block of code

import os
  if filename:
    if os.path.exists(filename):
      write_confirmed = QMessageBox.question(
        self,
        "Overwrite file?",
         f"The file {filename} exists. Are you sure you want to overwrite it?",
      )
    else:
      write_confirmed = True
    if write_confirmed:
      with open(filename, "w") as f:
        file_content = "YOUR FILE CONTENT"
        f.write(file_content)

which is responsible for handling already existing files when you want to save a file via QFileDialog.getSaveFileName(). Do I even need this? Apparently the native Windows dialog which pops up already checks if a file exists without me having to code the check myself.

[arctic kayak]

ThAt'S iLlEgaL

[mighty frigate]

@spring sinew afaik Qt already check for this. You can verify for yourself by browing the Qt code directly

[sleek hollow]

Is there a downside to the approach I use with a buffer list and manually do some filtering?

[spring sinew]

On Windows, and macOS, this static function will use the native file dialog and not a QFileDialog.
https://doc.qt.io/qt-6/qfiledialog.html#getSaveFileName

From what I understand, Qt just lets the OS native file dialog do its job when it is run on Windows or macOS. I don't use macOS but I would guess that its native file dialog also checks for existing files. Though I couldn't find anything about Qt's own file dialog checking for existing files if it e.g. runs on Linux.

Though this bug report https://bugreports.qt.io/browse/QTBUG-11539 and it being fixed makes me think that it does the check on Linux as well.

[mighty frigate]

@sleek hollow I don't think so. Other than it might be maybe less efficient.

@spring sinewthis is a very old ticket you got there

Qt4.6, in 2010

as to your problem, I have no idea. I've never tried for myself.

[sleek hollow]

Good to know. I'll have a look at the sortproxy when I'm at my pc next. I appreciate the help as always!

Hi!

Does anybody know how to get similar looking buttons with tkinter:

Best I have is this:

But first of all, the shadow is not in the right corner, and second of all, there is no "second border"

[vast tinsel]

try putting two buttons on top of eachother

[blissful fulcrum]

Oh... So there's no way to do this with a single element I guess

I'll use a frame instead

However, how can I make the shadow look so dark and be on the bottom right?

[obtuse acorn]

@blissful fulcrum

import tkinter as tk
win = tk.Tk()
win.geometry("50x50")
outer = tk.Frame(win)
outer.pack(fill="both", expand=True)
button = tk.Button(win, width=15, height=15, text="0", relief="raised", borderwidth=15)
button.place(x=0, y=0, width=45, height=45)
win.mainloop()

set your relief to raised and borderwidth to a decently large number

[obtuse acorn]

??? that's a bad recommendation, this is totally possible with just a button + config

[blissful fulcrum]

Oh wow, tysm!

On a slightly related note, are grids not expandable with tkinter?

I guess I could look that one up

[digital rose]

any help?

[obtuse acorn]

I really recommend the pack method after about 4 years of daily tk use prototyping etc

You will get cleaner / more consistent results if you avoid grid and use pack with the occasional use of the place method

[hollow pike]

hello guys,
I wrote a Tkinter GUI to display the images captured from the webcam on a canvas
a button on the right starts/stops the capture

what I'm doing is:

• assign to the button (buttonCaptureStartStop) a callback (start_capture) that will prepare and start the capture
• save the previous callback reference (start_capture) and assign a new callback to detect when the button is pressed (buttonPress), so that the function run using the after method (webcam_capture) knows when it should stop executing

I'd like to reduce CPU usage

• cap_delay used in .after() is 6ms, which theoretically limits the polling rate to ~166Hz, still a full thread (out of 8) of my i7-8550U seems to be in use (at 3.7GHz!)
• the FPS measured/reported on the Tkinter GUI can go up to 29.9-30.0, although sometimes the value drops to 20-25 FPS

is this a normal CPU usage? is it because 20-30 images have to be converted to Tk/drawn every second? (I guess the answer is yes?)

the script is located here: https://github.com/alex-fdias/computer_vision/blob/main/webcam_capture_tkinter.py

[obtuse acorn]

Reduced the columns to ones that really matter, the side-bar is now resizable and supports images, various text files, json loading and saving with configurable indents, and project details

Last step is git integration, and maybe a diffing system?

Does anyone know how I properly import tkinter & TKFileDialog

(python3)

Hey! Do someone know how to change the window's icon with the customtkinter library?

[hot mesa]

from tkinter import *
window = Tk()

window.geometry("1080x720")
window.resizable(False, False) 

window_icon = PhotoImage(file='icon.png')
window.iconphoto(True, window_icon)```

[restive mist]

I'm not using tkinter

I'm using customtkinter

[hot mesa]

oh mb

I thought you could still just use the normal Tkinter icon with it

Hi Guys!

[wary orchid]

you can research building a calculator with tkinter or a user login interface

[granite acorn]

Is there anybody who knows how I can add external image folders, font folders to bulldozer?

I want to make an apk

[somber hemlock]

Its still the same in tkinter

[somber hemlock]

do

import tkinter.filedialog as tkfd

and then use it everywhere like

tkfd.asksaveas(...)
tkfd.askopemfile(...)

This is better than a star import
Also showerror is from tkinter.messagebox

[somber hemlock]

Where is this HTML button? On a website or stored locally?

Can somebody help me with Tkitner?
I want to get the output from a for loop displayed in my GUI, any tips how to do it? I created Text widget, but my output come out when for loop is over, and i want it to be displayed in real time.

[short badger]

can i have grouped radio buttons

in tkinter

[short badger]

empty label i think right at least thats how it is in c#

and then set text to output (if im wrong im sorry and someone correct me ill delete messages)

[glossy frigate]

what would be the best python gui module to learn for relatively simple applications?

would pyqt be more useful to learn than tkinter?

I'm stitching together 2 icons to display on a QListView's decoration role, but for some reason the background of the stitched image is very noisy. The images are stitched nicely, but does anyone know what might be causing this noise?

My guess it has something to do with transparency?

Found painter.setCompositionMode(painter.CompositionMode_Source) which cleans up the noise to at least be black (still not transparent though). I can deal with that though, haha

[buoyant fulcrum]

Hi Guys! I'm working with tkinter.
I have a main window, but I want a toplevel window to open on my second screen.
How do I make a tkinter window open on my second monitor?
Thank you

[somber hemlock]

Call tkinter.update_idletasks() inside the for loop

I forget the name

[buoyant fulcrum]

if you have a loop, couldn't you just config the label?

or call a function that does?

[somber hemlock]

Yes but it won't get updated in real time

It will update only once at the end of the loop

[buoyant fulcrum]

ahh without time.sleep

[somber hemlock]

Don't use time.sleep

[buoyant fulcrum]

I used that to make mine update every 0.05 seconds

[somber hemlock]

Nor .after is needed

@sleek hollow I assume you've painted the image yourself. Have you paint the background also ? This isn't something I've seen before, looks like a random background to me

[short badger]

can you group radio buttons in tkinter

i need to have 36 buttons

[sleek hollow]

It's painter + pixmap and I'm using it to draw 2 pixmaps together. I didn't do anything special to handle the background though

[sleek hollow]

Yes, you can assign an IntVar to any button you want to be part of the same group

[short badger]

sorry, i mean like to where i can cut down on code instead of having 36 lines formatting buttons

and instead have 9 with buttons in groups of 4 for that purpose, not just for the var and values

[mighty frigate]

@sleek hollowcould you show me the code pls

[smoky needle]

Hi, i am currently trying to make app in PyQt and i want to have framed window, without title bar, but still have resize functionality like other apps (e.g. if you drag it on side, it will resize, resizing via cursor at all, etc.) How can i achieve that?

Currently i have this code for losing frame but that is not what i want

self.setWindowFlag(Qt.WindowType.FramelessWindowHint)

[mighty frigate]

@smoky needle I believe there's no default titlebar

from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
import sys

app = QApplication(sys.argv)

mainwidget = QWidget()
mainwidget.setStyleSheet("background-color: red;")

mainwindow = QMainWindow()
mainwindow.setFixedSize(400, 600)
mainwindow.setCentralWidget(mainwidget)
mainwindow.show()

app.exec_()

confirmed : no titlebar by default

[smoky needle]

That is not what i want, i want to remove title bar, but have still a frame around my app

[mighty frigate]

iirc you can choose to use the window manager or not use the window manager

but you can't choose what part of the window manager you want to use and which part you want to remove

[smoky needle]

How to choose to use window manager?

[mighty frigate]

this is what you're already doing

while incomplete, that's the right idea

from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtCore import Qt
import sys

app = QApplication(sys.argv)

mainwidget = QWidget()
mainwidget.setStyleSheet("background-color: red;")

mainwindow = QMainWindow()
mainwindow.setFixedSize(400, 600)
mainwindow.setCentralWidget(mainwidget)
mainwindow.setWindowFlags(Qt.WindowType.ToolTip | Qt.WindowType.FramelessWindowHint)
mainwindow.show()

app.exec_()

but then you loose all features provided by the OS window manager

that means you'll have to write your own drag and your own resize, for example

[spring sinew]

import sys

from PyQt6.QtCore import Qt
from PyQt6.QtGui import QPainter, QPixmap
from PyQt6.QtWidgets import QApplication, QLabel, QMainWindow

class MainWindow(QMainWindow):
  def __init__(self):
    super().__init__()
    self.label = QLabel()
    self.canvas = QPixmap(400, 300)
    self.canvas.fill(Qt.GlobalColor.white)
    self.label.setPixmap(self.canvas)
    self.setCentralWidget(self.label)

  def mouseMoveEvent(self, e):
    pos = e.position()
    painter = QPainter(self.canvas)
    painter.drawPoint(QPointF(pos.x(), pos.y()))
    painter.end()
    self.label.setPixmap(self.canvas)

app = QApplication(sys.argv)
window = MainWindow()
window.show()
app.exec()

I generated a small window where I can draw points by pressing down the mouse button and moving the mouse. I want to be able to draw without having to press down the button first. I found out that you need .setMouseTracking(True) for that. I have no clue how to actually implement that though. From how I understood it, self.setMouseTracking(True) in the initialisation of the MainWindow class should do the trick but it's not working. Neither did self.label.setMouseTracking(True).

[mighty frigate]

import sys

from PyQt5.QtCore import Qt
from PyQt5.QtGui import QPainter, QPixmap
from PyQt5.QtWidgets import QApplication, QLabel, QMainWindow

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.label = QLabel()
        self.canvas = QPixmap(400, 300)
        self.canvas.fill(Qt.GlobalColor.white)
        self.label.setPixmap(self.canvas)
        self.setCentralWidget(self.label)

        self.label.setMouseTracking(True)
        self.setMouseTracking(True)

    def mouseMoveEvent(self, e):
        pos = e.pos()
        painter = QPainter(self.canvas)
        painter.drawPoint(pos.x(), pos.y())
        painter.end()
        self.label.setPixmap(self.canvas)

app = QApplication(sys.argv)
window = MainWindow()
window.show()
app.exec()

@spring sinew

reason : the moues isn't actually over the mainwindow, but over the label. That's why you have to enable the mouse tracking for the label

but this won't be enough : if you don't enable the mouse tracking for the mainwindow too, the event won't be transmitted from the label to the mainwindow

[spring sinew]

I guess your first new line should be self.setMouseTracking(True) though?

[mighty frigate]

am sorry what

[spring sinew]

You added self.label.setMouseTracking(True) twice.

[mighty frigate]

ah indeed, too fast of a refactory

[spring sinew]

But you said you'd need to enable it for the main window and the widget

[mighty frigate]

corrected

that's what the 2 last lines do

[smoky needle]

And how can i keep that OS window manager but remove title bar?

[mighty frigate]

p.s: using eventFilter can help you debug and understand those kind of problem

@smoky needleI told you twice already, to my knowledge you can't. Because the title is handled by the window manager, not by Qt.

at least not with QtWidgets

[spring sinew]

I will look into that. Just playing around with some basic functionality for now. Thanks for the help

[mighty frigate]

@spring sinew a small example to illustrate

import sys

from PyQt5.QtCore import Qt
from PyQt5.QtGui import QPainter, QPixmap
from PyQt5.QtWidgets import QApplication, QLabel, QMainWindow

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.label = QLabel()
        self.canvas = QPixmap(400, 300)
        self.canvas.fill(Qt.GlobalColor.white)
        self.label.setPixmap(self.canvas)
        self.setCentralWidget(self.label)

        self.label.setMouseTracking(True)
        self.setMouseTracking(True)

        self.label.installEventFilter(self)

    def eventFilter(self, target: 'QObject', event: 'QEvent') -> bool:
        if target == self.label:
            print(event)
        return super().eventFilter(target, event)

    def mouseMoveEvent(self, e):
        pos = e.pos()
        painter = QPainter(self.canvas)
        painter.drawPoint(pos.x(), pos.y())
        painter.end()
        self.label.setPixmap(self.canvas)

app = QApplication(sys.argv)
window = MainWindow()
window.show()
app.exec()

@spring sinew one other thing : if you want to draw lines instead of dots, what you could do is memorise the last position of the mouse, and draw a line from the last position to the new one on each move

[sleek hollow]

#Images I want to combine
Valid = QtGui.QPixmap(':/confirm.png')
Invalid = QtGui.QPixmap(':/error.png')

#Pixmap to hold the resulting image
combo = QtGui.QPixmap(40, 20)

#Painter used to paint on the pixmap
painter = QtGui.QPainter(combo)
painter.setCompositionMode(painter.CompositionMode_Source)

painter.drawPixmap(0, 0, Valid)
painter.drawPixmap(Valid.width(), 0, Invalid)

Dummy = QtGui.QIcon()
Dummy.addPixmap(combo)

In the meantime, I'm likely just going to switch from ListView to TableView and use the columns to display the images I want instead

[mighty frigate]

painter.fillRect(combo.rect(), Qt.transparent)

untested, but somethign like that

[sleek hollow]

do that before any drawing?

[mighty frigate]

before the 2 draw()

what class is that in ?

[sleek hollow]

it's just part of my inherited QAbstractListModel class. It's an absolute mess because I was just testing with it and I was going to properly implement once I knew the logic worked

[mighty frigate]

alr

if you want to add more UX features, usually you want to implement a delegate

[sleek hollow]

Didn't seem to have any affect on it. Even tried commenting out the setCompositionMode

[sleek hollow]

Yeah, I'm still fairly new to model view in general so wanted to see what I could get away with before diving into delegates

but that seems to be the common reccomendation

[mighty frigate]

yeah model/view is a bit overwhelming in Qt

[sleek hollow]

It's so powerful though. It made this current task a breeze

[mighty frigate]

check if i'm not mistaken and the rect() is actually the correct rect, like (0, 0, 40, 20) or something

[sleek hollow]

PySide2.QtCore.QRect(0, 0, 40, 20)

[mighty frigate]

sounds alright

[sleek hollow]

I think the tableview solution is better anyways for now. I can keep adding more columns if I need more info icons

[mighty frigate]

what are you trying to accomplish again ?

sorry I have the memory of a fish

[sleek hollow]

I have a list of items and each of them has a view boolean attributes. I want an icon to represent those states of each item

[mighty frigate]

ok

so basically

[sleek hollow]

Right now I'm still just using an icon for 1 bool (the merged was a bust), and I'm colour coding the text for a different bool

[mighty frigate]

| name button1 button2 button3|
| name2 button1 button2 button3|

etc

[sleek hollow]

it's a list of assets for a game. The icons are meant to represent what stage they're at (has a model, has textures, has animation info, etc)

[mighty frigate]

ok

so yeah, listmodel listview and delegate

that's probably the best

tableview, I'm scared about the button press handling

[sleek hollow]

The only thing I need to worry about for that is selecting a row

another button handles loading from selection

[sleek hollow]

so what does delegate allow me to do icon-wise?

[mighty frigate]

the row of a table or a delegate ?

[sleek hollow]

I basically would expect the table view selection to behave exactly how the list view would

[mighty frigate]

that actualyl quite close

are you afraid of C++ ?

[sleek hollow]

Never used it

[mighty frigate]

welp

ok I'll need a sec

[sleek hollow]

I kinda get the gist reading the c++ docs for qt at least since the class/methods are all the same

but yeah, I get a bit lost in the structure

I guess my main question is where does the delegate live in relation to all the data?

[mighty frigate]

model = SomeModel()

delegate = SomeDelegate()

view = SomeView()
view.setModel(model)
view.setDelegate(delegate)

^ the basic usage

[sleek hollow]

I have my abstract list class that forms the model (holding my game asset objects), and that gets plugged into my listview

so is it QItemDelegate I inherit from for the delegate?

[mighty frigate]

class SomeDelegate(QStyledItemDelegate):
     def paint(self, painter, option, index):
          opt = option
          self.initStyleOption(opt)
          
          status_pixmap = index.data(MyCustomRoles.StatusRole)
          if not status_pix.isNull():
              status_icon_rect = QRect(opt.rect.x(), opt.rect.y(), status_pixmap.width(), status_pixmap.height())
              opt.rect.translate(status_pixmap.width(), 0)              
              opt.widget.style().drawItemPixmap(painter, status_icon_rect, Qt.AlignCenter, status_pixmap);

          opt.rect.setWidth(self.sizeHint(opt, index).width());
          super().paint(painter, opt, index);

^ this is the paint function of the delegate. Every item in the list is painted by it.

Here we're retrieving a pixmap representing a status; and if it exist we're modying the rectang where the item would normaly be displayed to make room for the new pixmap, and we're drawing it. After that, we let the default implementation of QStyledItemDelegate take care of the rest of the drawing.

so, in that function you have the painter (which is a QPainter) you already saw that one

option contains some datas related on the visuals : is the index selected for example

and index is the index from the model, you should more and less know what this is

this code also uses something I told you before about custom roles, if you remember

[sleek hollow]

yeah, there's predefined roles for certain operations but you can also define your own

[mighty frigate]

yes

this code draw the pixmap on the right of the item tho, not on the left

but you get the idea

[sleek hollow]

so ideally I would write a method that packs up all my bools like [0, 1, 1, 0, 0] and it knows which images to stitch together based on that?

[mighty frigate]

this isn't what I would do

I would have one role for each bool

[sleek hollow]

oh

[mighty frigate]

retrieve those datas in the paint()

and draw each pixmap one by one

[sleek hollow]

but then how would it refer to which image to draw?

[mighty frigate]

depends on you
