Python 3.5 tkinter: Widgets in Fenstergröße ändern

Question

Ich lese, lese und lese aber immer noch nicht die passende Antwort auf mein Problem. Ich plane ein 'Masterfenster' zu erstellen, in dem ich mehrere Frames implementiere (zur Zeit ein Navigationsfeld auf der linken Seite, ein 'RootFrame', der angezeigt wird, wenn kein Prozess läuft, eine Statusleiste unten, die für Alerts und Verarbeitungen gedacht ist und einen Hauptrahmen, den Code unten ausführend, funktioniert alles gut, aber die Rahmen passen sich nicht an die Größe des Fensters an.

Nun, ich weiß, ich muss ein paar Kleben in Haupt-und Unterklassen und setzen grid_column- und rowconfigure auf eine Gewichtung von> 0

Ich kann den Grund nicht sehen, was fehlt mir? Muss ich alles in einen anderen Masterframe stecken ?? was ich am Masterfenster festhalte? kann nicht stimmen, da ich Frames überall vererbe ...

Danke für Ihre Mühe und Eingabe. rgds

ps: ach übrigens: kann any1 mir sagen, wie man durch die Zeilen in einer Grid-Methode iterieren, so dass ich einfach sagen 'Gitter das Widget in der nächsten Zeile' (relativ) und nicht verwenden müssen absolute ganze Zahlen?

Answer 1

Sie vernachlässigen alle Zeilen oder Spalten im Stammfenster. Ohne es weiß tkinter nicht, wie Sie zusätzlichen Speicherplatz reservieren, wenn Sie die Größe des Fensters ändern.

def main(cls): 
    ... 
    root.grid_rowconfigure(0, weight=1) 
    root.grid_columnconfigure(0, weight=1) 

Da Sie nur ein einziges Widget im Hauptfenster setzen, empfehle ich pack da Sie alles in einer einzigen Zeile erreichen können.

self.pack(fill="both", expand=True)
