In the attachement simple app that shows the problem. Try to drag and
drop to the view...
Hi.
I'm doing dropping to the QGraphicsView some data.
I successfully receive dragEnterEvent( QDragEnterEvent * event ) and
here accept action with event->acceptProposedAction().
But I don't receive dropEvent on dropping and cursor shows that my
view doesn't accept drop.
Why? What am I doing wrong?
