Hi,
Currently I have a QTreeWidget with drag/drag enabled, successfully copying/moving items.
However, this is not fully correct. My QTreeWidgetItems are subclassed (type being indicated in UserRole) and I only want to allows keys of certain types to drop in keys of certain other types.
I've subclassed QTreeWidget and overridden mimeData and dropMimeData to allow me to encode/decode custom information. However with my custom mime format I now get a you cannot do that icon (circle with line through it) when I go to drop it in the desired location.
Where does QTreeWidget decide if a drop can be made on a given it? I did try to override event, looking for QEvent:ropMove but it does not seem to come in there.
Help appreciated,
Simon
