ich habe ein Programm geschrieben, das eine eigene Bildschirmtastatur beinhaltet. mein Problem ist, dass wenn ich den Curser in die Console der GUI setze und dann auf einen Button auf dem Tastatur-Toplevel klicke, das Hauptfenster mit der Console den Fokus verliert und das Tastaturtoplevel fokusiert wird. dadurch erscheint der angeklickte Buchstabe nicht in der Console.
hier mein vereinfachter Code:

oder gibt es ein besseres widget als das Toplevel um die Tastatur umzusetzen?
sie soll aber weiterhin frei beweglich sein, also frei platzierbar...
Hauptfrage: Wie bekomm ich es hin, dass wenn ich auf einen Button der Tastatur klicke das entsprechende Zeichen auch in der console (also dem Textfenster) angezeigt wird?
