QGraphicsView scroll to zero by adding a QGraphicsTextItem
Message 1 in thread
Hi,
QGraphicsView is always scrolling to 0,0 when I add a QGraphicsTextItem
on the Scene. It is not the case with QGraphicsSimpleTextItem
Am I doing something wrong or is it a bug?
I am working with Qt4.2.2
Best regards,
Sebastien

Sounds familiar. IIRC I got around this by setting the position
correctly (default is (0,0)) and then making the text visible.

It's a known bug that was fixed in 4.3 a while back. If you want to patch up
your 4.2.2, look at a recent 4.3 snapshot, pull up qgraphicsitem.cpp, and
look at the QGraphicsTextItemPrivate::_q_ensureVisible() function.
