Solved How to calculate range in QScrollBar?
-
Hi,
I have QScrollArea and big widget on it ( 1000x2000 ):
this->setWidget(bigWidget);
so QScrollArea has vertical QScrollBar too. I would like to know how can I calculate range values. When verticalScrollBar is up, the value is 0. I would like to know what is maximum Value ( when the verticallScrollBar will be on down ). When my BigWidget has height = 312, maximum value for verticallScrollBar is 1690.
1690 + 312 = 2002 != 2000
So why that 2?

the extra 2 pixel are coming either from the top/bottom border or margin/padding in a layout etc
check the value returned from frameWidth() of the scrollarea widget -
