Scroll Bar Problem

[zgulser]

Hi,

I have a scroll vertical scroll bar by my list widget. When I use mouse wheel it moves both upward and downward which is fine. But when I try to this via mouse left button(more precisely mouse click) it doesn't move upward, moves only downward.


By the way my list widget stays in another widget(frame). Whwn I get it of this frame, list widget moves both upward and downward with both wheel and button.
