pyright can't resolve PyQt (PySide6) events?

[amigaosz]

Hello I have a stupid problem with pyright I can't solve myself.

I have the following class file which works without any problems:

from random import choice
from PySide6.QtWidgets import QPushButton, QMainWindow, QLabel, QLineEdit, QVBoxLayout, QWidget

window_titles = [
    "Some sample text",
    "Even more text",
    "Oh no! No more lemmings!",
    "This is really a lot of text",
    "Stop texting me"
]

class MainWindow(QMainWindow):

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

        self.label = QLabel()

        self.input = QLineEdit()
        self.input.textChanged.connect(self.label.setText)

        self.button = QPushButton("Press Me!")
        self.button.clicked.connect(self.clicke_di_click)

        layout = QVBoxLayout()
        layout.addWidget(self.input)
        layout.addWidget(self.label)
        layout.addWidget(self.button)

        container = QWidget()
        container.setLayout(layout)

        self.setMinimumSize(300, 240)
        self.setMaximumSize(600, 480)
        self.setWindowTitle("My App")

        self.windowTitleChanged.connect(self.window_title_change)

        self.setCentralWidget(container)

    def clicke_di_click(self):
        new_window_title = choice(window_titles)
        self.button_toggle_status = self.button.isChecked()
        self.setWindowTitle(new_window_title)

    def window_title_change(self, window_title):
        print(f"Oh no, the window title changed to: {window_title}")

    def __str__(self):
        return "Window Module"

But when checking my code with pyright on the command line (installed with pip) I get the following output when linting this code:

No configuration file found.

I can ignore it but I would really like to use coc-pyright inside vim and this addon shows me also three errors in the editor.

What am I doing wrong and how can I solve it?

It looks like you're using a "pyproject.toml" configuration file. What configuration options have you provided for pyright?

Which version of PySide6 do you have installed? The latest version is a "py.typed" library, which means that it includes inlined type annotations and should therefore work with static type checkers. When I ran "pip install PySide6 --upgrade", it installed version 6.2.4. When I use this version with pyright's default settings, I'm not able to repro the errors you're seeing. That means your configuration must be different than mine.

I'm having the same issue here using PySide6 version 6.3.0
Code:

import sys
from PySide6 import QtCore, QtWidgets, QtGui


class HelloWorld(QtWidgets.QWidget):
    def __init__(self):
        super().__init__()

        self.button = QtWidgets.QPushButton("Push me!")
        self.button.clicked.connect(self.magic)

    @QtCore.Slot()
    def magic(self):
        print("magic")


def run():
    app = QtWidgets.QApplication()

    widget = HelloWorld()
    widget.setWindowTitle("Hello World!")
    widget.resize(500, 500)
    widget.show()

    sys.exit(app.exec())

Output:

The class QPushButton defined in the file PySide6/QtWidgets.pyi does not contain a method or attribute called clicked, nor do any of its parent classes. If you think that the stub file is in error and this class should expose a member with that name, please file a bug with the maintainers of PySide6.

Thanks for the quick response!
