mal wieder ne Frage in Tkinter: Ich habe ein kleines Testfenster programmiert, um dem Styling mit ``ttk.Style()`` näher zu kommen. Daher wollte ich verschiedene Stylings beim Klicken auf einen Radiobutton aktivieren. Nur leider ändert sich das Design nur bei den Labels?
Warum aber ändert sich bei den Entries/Comboboxes nichts, wenn man auf den zweiten Stylingbutton klickt?
Hier der Code:
