ich schreibe gerade mein erstes komplexeres Programm mit GUI
eigentlich relativ simpel, allerdings hänge ich gerade an einer absolut trivialen Stelle
In meinem GUI soll standartmäßig ein Text der in ein Feld eingegeben wurde nach Bestätigung in einer Liste ausgegeben werden. (code folgt am Ende)
Leider Wird langer Text fortlaufend und ohne Zeilenumbruch ausgegeben (achja, es sind auch eigentlich 2 Listen, eine im Startfenster und eine in der Alle Daten zusammengefasst ausgegeben werden)
Aus der Tkinter Bibliothek habe ich dafür den Befehl wrap=tk.WORD
Auf der Suche hier im Forum habe ich beim einzigen Beitrag zu dem Thema die Aussage gefunden, dass Tkinter widgets einen Zeilenumbruch automatisch machen...
Naja irgendwie klappt bei mir beides nicht
Stehe ich gerade so sehr auf dem Schlauch???
Hier mein Code:

self.title_entry = tk.Entry(self.master, font=("Helvetica", 12), fg="grey")
