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?
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.
