[Qt-interest] QMimeData problems between a QTableWidget and a QTreeWidget

[Andrei Cimpean]

Sweet, it works now. 
But, I have another question. When I get with the item i want to drop into the tree, it shows me under the cursor something that looks like a block. The method works, but this detail is kinda bothering.
Is there something I need to set with drag->exec() method call in order to set this functionality or am I missing something in the tree class?

Thanks for the help.
