Hi...

I've a QGraphicsView and I've set a custom scroll bar with setVerticalScrollBar().
It change the default scrollbar but I've two problem:

1) If I try to resize this scroll bar more than the default..half of it is hidden. I've tryed with many solution but I can't see all the new scroll bar.

2) Does anybody know a way to make it possible that If a user press with the mouse (and not whit keyboard PagDown or arrow keys) a scroll bar...this scroll bar can slide with a predefinite minimum value (and not for all the value of the slider)??!!

I want to make the same about press the Page Down key (set whit setSingleStep()) and the mouse that grab the scroll bar.

Thanks
