Drag from tree widget

[EricF]

I seem to remember this is a necessity on Windows.

This was part of QDrag implementation, QDrag::start adds Qt::CopyAction not the windows specific implementation. It's kind of funny though as this function is declared obsolete and they still use it. QDrag::exec() accepts a defaultDrop which would to the trick I think.

If you are the one creating the mime data, you can subclass it or provide the data you need in some other way to carry it with the object to the drop site.

Yeah I know because I'm already subclassing the mime data, it's just that I didn't want to add data for this specific drop target. Anyway, it works now. Thanks, again.
