[closed] "checked" variable (attribute?) origin?

[paul18fr]

Ok I think I finally figured out: if I want something to be printed (or checked) when the signal is sent, one need to define a variable that "sets" the boolean.

import sys
from PySide6.QtWidgets import QApplication, QPushButton


def Anyfunction(AnyArg_JustSomething):
    print(f"AnyArg_JustSomething  = {AnyArg_JustSomething}")


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

    button = QPushButton("press me to send a signal")
    
    button.setCheckable(True)           # must be set to True to allow signal(s)
    button.toggled.connect(Anyfunction)    # signal

    button.show()
    sys.exit(app.exec())

Output:
AnyArg_JustSomething  = True
AnyArg_JustSomething  = False
AnyArg_JustSomething  = True
AnyArg_JustSomething  = False
AnyArg_JustSomething  = True
AnyArg_JustSomething  = False
...
