python get checkbutton value nach Ende des Mainloops

Question

Ich möchte herausfinden, welche Checkbuttons nach dem Schließen der Anwendung überprüft wurden. Wenn ich Checkbuttons Werte in einer Sammlung speichern, ist es nicht möglich, Zugriff auf diese Sammlung zu haben, nachdem die Anwendung zerstört wurde.

app = Application(path_to_files) 
app.initialize(data) 
app.mainloop() 
#i want to know all checkbuttons values on this line

OK, modifizierte ich Ihren Code ein bisschen. Sie finden Erklärungen als Kommentare innerhalb des Codes. Ich habe die Protokollmethode (die Sie mit self.master.protocol aufrufen können) hinzugefügt und die close-Methode geändert, so dass sie die Anwendung durchläuft, bevor sie die Anwendung löscht und die Flags in einem Verzeichnis sammelt, das dann in eine globale Liste konvertiert wird.

Um es zu testen, musste ich den Bildteil Ihres Codes auskommentieren und meine eigene Spielklasse erstellen, um eine Liste mit gefälschten Spielen zu erhalten.
Ich weiß nicht, ob meine Lösung elegant ist, aber unter meinen Testbedingungen hat es funktioniert.

So nach app.mainloop() versuchen Sie print(out), die Ihnen eine Liste von Nullen und Einsen geben wird.

Ich hoffe, es hilft. Ah, und bitte überprüfen Sie den Einzug! Dieser Editor hat hier etwas seltsames gemacht, als ich meinen Code eingefügt habe.
