zu meinem Code, habe ich Fragen.
Ich möchte
Wenn ich in QLineEdit eine virtuelle Tasteneingabe z.B. "self.setText(os.sep)" mache, werden nicht die Pfade von / root im Completer ausgegeben.
Ich habe schon versucht in Code-Zeile 35 einen Ansatz zu finden, leider ....
Gibt es eine Möglichkeit, dies umzusetzen?
Grüße Nobuddy

Und bei dem f-String verstehe ich nicht was Du damit überhaupt sagen willst. Auch hier: einfach weg lassen und den Wert so nehmen wie er ist, denn in beiden Fällen wird ja der Wert nicht verändert, man könnte den also gleich so nehmen.
