I noticed you don't call the super methods in your reimplemented event handlers. If you determine you don't want to handle the item you can ignore it in the move event. Otherwise you could let the item drop using the default implementation. But if you really do need custom drop logic because you want to decide what exactly to copy to the new item, and where it goes, then yea you would have to handle the stuff like if it's dropped as a sibling of the item or as a child. Or if it really does replace the previous item. To determine if you should make it a sibling drop above or below you can get the visual rect of the drop target item and check where the drop event falls in relation to the center y http://doc.qt.io/qt-4.8/qabstractitemview.html#visualRect > My other question is if I am doing right the dropEvent(), because all I am > doing is creating a new item and copying the text of the item in the left. > I will also copy the data stored as userRole. > But is this a real drag and drop?

A widget receives a drip event with mime data and they interpret it somehow. Then the caller that initiated the drag receives the results of whether it was accepted and which action was used. So if it were a move, then the caller knows to delete their instance. But for a copy, the receiver is applying a copy of data. > R > > > El sábado, 8 de abril de 2017, 4:01:21 (UTC+1), Justin Israel escribió: > > If you now have the drop position from the QDropEvent, then you should be > able to inspect the item under the position via itemAt > > http://doc.qt.io/qt-4.8/qtreewidget.html#itemAt > > From there you can choose how you want to insert > > Justin > > On Sat, Apr 8, 2017, 4:10 AM Rudi Hammad <[email protected]> wrote: > > sorry, badLink.
