[Interest] QGraphicsSceneMouseEvent, mapFromScene...

[Alexander Semke]

Hi,

I'm having here a problem with mapFrom/mapTo-functions. In a class derived 
from QGraphicsItem I override mousePressEvent and I get for 
mapFromScreen(event->screenPos()) a point that is different from event->pos().
Similarly, mapToScreen(event->pos()) doesn't lead to event->screenPos(). Why?
There is something here that I don't completely understand... 
Can somebody help?


Best regards
Alexander
