First of: thanks for the answer. I probably should consider going to the KDE- devel but honestly, I forgot about it. ;-) Yes, those are inner drag & drops, and are not meant to handled outside of the application. The approach you suggested would work, but I would like to use type in the QMimeData and properly accept, just because this would provide user visual feedback (cursor change to no-drop) if the drop will not be accepted. ___________________________________________________ This message is from the kde mailing list.
