[Qt-interest] Scrolling QScrollArea with mouse near borders?

[Soboljew, Patrick]

Hi again,

I've found a solution for my problem: the widget that gets passed to the
scroll area gets a pointer to the scroll area. Addiontionally it
overwrites the mouseMoveEvent method of QWidget. In the mouseMoveEvent I
call the ensureVisible method of QScrollArea with the coordinates of the
mouse pointer. It seems to work perfectly.
