[Qt-interest] QTReeWidget Drag and Drop

[sarvesh saran]

Hi Sujan,

you can get some pointers on how to begin here:
http://doc.qt.nokia.com/latest/model-view-programming.html#using-drag-and-drop-with-item-views

and an example can be seen here:
http://sector.ynet.sk/qt4-tutorial/dnd.html

hope this helps!
