Qt: how to set main window's initial position?

I think the normally window manager determines the initial position of the QMainWindow position on the desk top. I want to set the initial position myself. How is this done with Qt on Windows?

You can restore the window geometry with restoreGeometry(), and the state of docked elements with restoreState(), during the construction of your MainWindow...

    QSettings settings("yourcompany", "yourapp");

    restoreGeometry(settings.value("geometry").toByteArray());
    restoreState(settings.value("state").toByteArray(),YOUR_UI_VERSION);

Then, if you override closeEvent(), you can save the state as follows:

    QSettings settings("yourcompany", "yourapp");
    
    settings.setValue("geometry", saveGeometry());
    settings.setValue("state", saveState(YOUR_UI_VERSION));

YOUR_UI_VERSION is a constant you should increment when your UI changes significantly to prevent attempts to restore an invalid state.

I believe you're looking for setGeometry.
