QGraphicsScene doesn't accept Drops

[momesana]

Thank you all for replying to my post.
The reimplementation of dragMoveEvent did the trick .
I was really frustated yesterday after I couldn't get it to work after 5 hours of trial and error experiments. Today I was demoralized enough to give up and try another approach. I made the QGraphicsView catch the Event.

This also failed so I looked up the Qt Drag and Drop online documentation and searched for examples and noticed that in the examples dragMoveEvent is also implemented. I did the same and QGraphicsView could successfully catch the events. But it didn't come to my mind to apply this knowledge to GraphiscScene. I just tried it now after reading your replies and it works. Thanks jpn

It's because QGraphicsScene provides a default implementation of dragMoveEvent that checks if there are items on the scene under the cursor that accept drop events. If not, the event will be ignored, and you won't be allowed to drop.
