ich steige gerade in das Thema Python ein und bin nun vor einem Problem gestoßen, dass ich seit vielen Stunden versuche zu löse.
Ich möchte für mich ein kleines Tool bauen, welches verschiedene Formen beinhaltet. Ich habe mein Repo wie folgt geordnet:
- docs (Folder)
- gui (Folder)
- researchtool (Folder)
- tests (Folder)
- assets (Folder with images)
- gui_mainmenu.py
- gui_summarization.py
- gui_settings.py
Mein Problem betrifft aber jedoch eher der gui_mainmenu.py und gui_summarization.
Ich möchte über die Form Mainmenu die Form Summarization aufrufen und wenn ich wieder die Form Summarization schließe die Form MainMenu aufgreifen.
Ich habe in der Dokumentation gelesen, dass dies über TopLevel und Klassen funktioniert und habe mich auch mithilfe dieses Tutorials versucht dies für meinen Fall zu lösen. Der einzige Unterschied ist, dass ich dies in Python Skripte trennen möchte. Dies ist für mich einfach wichtig, dass ich GUIs auch als Dateien trenne.

Ich hoffe man kann hier weiterhelfen, dass ich über MainForm die Summarization Form aus einer anderen Python Datei aufrufen kann. Viele Tutorials, die ich mir angesehen habe, arbeiten mit der GUI aus einer Datei heraus und konnten mein Problem nicht wirklich lösen.
