Drag and Drop in QT4

[batileon]

Actually I m using the Q3ListView

What I want to do is just like there is a tree with some nodes(which are some folder) or left side, and there are some icons on the right(IconView items), and can drag the icon to different nodes.

Actually the code works well in QT3, so I want to know is there anything I need to set in order to let the tree listview accept the icon drag.

have you set setAcceptDrops(true)?

[batileon]

Yes, I have set that
I think the problem now is that there's still a "no entry" icon shown when I drag the item to the ListView tree, which means even I have set setAcceptDrop(true), seems it still reject dropping....... >.<
