@Taulmarill:
Habe es einigermassen gelöst.

@ptk:
Wie geht genau das mit Containern?




-----------
Das Ganze klappt nun, aber noch nicht so wie gewünscht.
Ich möchte mehrere Events einbauen.

z. B.
- Einfacher button
- Button der gedrückt bleibt egal wohin mal mit der Maus geht.
(while buttondown -> button = gedrück)
