Programmatic QGraphicsView scrolling not updating properly

Question

I have a custom class derived from QGraphicsView that implements a slot call scrollHorizontal(int dx), inside the code is simply

void CustomView::scrollHoriz         


        

Answer 1

You are not supposed to call scrollContentsBy as explained here: http://qt-project.org/doc/qt-4.8/qabstractscrollarea.html#scrollContentsBy

I don't know if you can still call the hidden scrollbar to scroll it. If not, translate is an option.
