[Interest] Re-ordering items in QListWidget by drag-and-drop

[Stephen Chu]

I am showing a list of item in a QListWidget and would like to allow 
user to reorder them by drag-and-drop.

I set the movement to free but it doesn't really do anything. I can't 
even select any of the items. The selection mode is set to SingleSelection.

What else should I set so I can reorder items? Or does QListWidget not 
support it?

Thanks.

Stephen
