// bemerkungen : wenn paintEvent aufgerufen wird, wird das komplette
//               widget gel<65>scht und nur die sachen gezeichnet, die in
//               paintEvent stehen ! sollen dinge z.b nur bei maustasten-
//               druck gezeichnet werden, so mu<6D> dies in mousePressEvent
//               stehen !
//               paintEvent wird aufgerufen, falls fenster <20>berdeckt wird,
//               oder auch einfach bewegt wird
