Good morning
I have a problem by centering the scrollbar with a large label.
I made a Scrollbar with a label witch has a large text in it. With an menu
I try to set the position off the bar at the center off the text. (see the
example).
It seems that setPosition sets the postion off the beginning off the bar
and not really centered off the text.
Has anybody an idea how I can set the scrollbar centered?
Regards
Marcello
