Speichern und Wiederherstellen von Dockwidgets Position und Größe

Question

Ich kann nicht ganz herausfinden, wie die Sicherung und Wiederherstellung funktionieren soll, so dass ich die Dockwidgets Geometrics speichern kann, wenn die Anwendung geschlossen und erneut geöffnet wird. Ich habe 5 Dockwidgets, die ich gerne haben würde.

Ich nehme ich beide restoreState und saveState jeweils in init und close verwenden. Aber wie konfiguriere ich es?

Das funktioniert hier:

def __init__(self): 
    self.readSettings() 

def closeEvent(self, event): 
    print('closing') 
    settings = QSettings() 
    settings.setValue('geometry',self.saveGeometry()) 
    settings.setValue('windowState',self.saveState()) 
    super(Window, self).closeEvent(event) 

def readSettings(self): 
    settings = QSettings() 
    self.restoreGeometry(settings.value("geometry").toByteArray()) 
    self.restoreState(settings.value("windowState").toByteArray())
