View Full Version : Drag and drop between QListWidget's

21st April 2008, 05:47
Hi friends,

I need guidance to do the drag and drop between two QListWidget designed in the designer. By dragging an item of the first QListWidget for the second, should be checked if this item already exists in this second QListWidget. If it does, it is removed from the first and added the second.

Thanks for reply, wisota...

I created a form in the designer with two QListWidget, with the properties to "true" to acceptDrops, dragEnabled, dragDropOverwriteMode and dragDropMode = QAbstractItemView: DragDrop. The big question is whether you do what I just drawing these QListWidget in designer and in writing any code, without having to write a class based on QListWidget and reimplementar functions of drag and drop.

You'll surely have to subclass QListWidget... The default implementation of QListWidget will do something close but not identical to what you want out of the box.
