Access Action declared in main.py from mainwindow.py

britesc

I have a main.py that houses the standard declarations and calls to setup up a QApplication, app and window. Within this I am also constructing a QSystemTrayIcon which works. Currently I have "Show" and "Quit", but I would like to toggle the "Show" to "Hide" and back to "Show" as I show and hide the mainwindow.
Next I have a mainwindow.py. In here I have overridden the showEvent and hideEvent . That also works.
Now I would like to use these to toggle the System Tray Menu for the "Show" and "Hide" entries / actions appropriately.

My question is how do I access the actions constructed in main.py from mainwindow.py which will allow me to set the relevant actions visible or not.

Thanks as always,
jB

main.py

def main() -> None:  # sourcery skip: extract-method, remove-pass-body, remove-redundant-pass, swap-if-else-branches
    """ Start the Main Function to get us going. """
    try:
        app = QApplication(sys.argv)
        window = MainWindow(app)
...
            tray_menu = QMenu()
            action1 = QAction("Show")
            action1.triggered.connect(window.showNormal) # type: ignore
            action1.triggered.connect(window.activateWindow) 
            action1.triggered.connect(window.raise_)
            action1.setIcon(QIcon(u":buttons/buttons/glassRound/glassButtonShow.png"))
            tray_menu.addAction(action1)

            action2 = QAction("Hide")
            action2.triggered.connect(window.hide) 
            action2.setIcon(QIcon(u":buttons/buttons/glassRound/glassButtonHide.png"))
            action2.setVisible(False) 
            tray_menu.addAction(action2)

mainwindow.py

class MainWindow(QMainWindow, Ui_MainWindow):
    """ The MainWindow Class. """
    def __init__(self, app) -> None:
        super().__init__()
        self.setupUi(self)  # type: ignore
        self.app = app  # declare an app member
 ...
    def hideEvent(self, event: QHideEvent) -> None:
        print("Hide Event Triggered")
>>> HERE IS WHERE I WANT TO ACCESS THE ACTIONS FROM main.py <<<
        return super().hideEvent(event)
    
    def showEvent(self, event: QShowEvent) -> None:
        print("Show Event Triggered")        
>>> HERE IS WHERE I WANT TO ACCESS THE ACTIONS FROM main.py <<<
        return super().showEvent(event)
    ```

If you choose to declare/define them in main() you will need to pass them as parameters to MainWindow, or pass tray_menu and read its actions, or via a setter exported from there, or some equivalent.

Whether the actions might be better declared in MainWindow is a different matter. Probably depends how/where you use them.

Hi,

Since these actions are there to manipulate the main window and updated by it, I would recommend that you create them in your MainWindow class and then retrieve them from it to be added to your QSystemTray object.
