update im fenster ???

Hi !
Wie kann ich die Elemente im Fenster updaten, weil immer, wenn ich das Fenster verschiebe, dann ist z.b. der Button weg oder b.z.w. wird nicht mehr neu gezeichnet.Gibts da eine Funktion ???

Nimmst du Standard-Buttons oder malst du deine selber? Das ist auf jeden Fall nicht normal ;). Zeig mal ein bisschen Code :).
