I’m using my custom item model (subclassed from QAbstractItemModel) with custom QTreeView. I want to allow internal drag-n-drop movement (MoveAction) and, when modifier key or right mouse button is pressed, pass CopyAction to my model (to dropMimeData) to copy items. However, default implementation of dropEvent() in QTreeView seems (from C code) only capable of passing […]
