But everytime if i just move over with the cursor, the painter paints the bounding rect
white -> the green outline which is painted in a other class is overpainted.

found the problem, actually it is not a problem, just the way relalizes what has or will be updated.
Changed the properties that one change in the child object, letÅ› all other itmes per default also be redrawn....
