QTreeWidget (Qt 4.3) - how to handle custom drag/drop?
Message 1 in thread
How is one supposed to implement the back-end side of a drag/drop
operation within the tree widget? I'd like the QTreeWidget to do the
front-end side of it - ie. managing the visual part of the drag/drop,
but let me rearrange the items internally once the "drop" happens. I
don't want it moving the items around.
Also - there seems to be (at least one) bug. If I override
supportedDropActions() to only return Qt::MoveAction, then no drag
happens at all. It seems it only starts up if CopyAction is also
returned. But I don't want to copy the items - just move them.
Rather confusing.
