[Qt-interest] Mouse double click.

[Alexandre Beraud]

Hi,

In your QTreeView derivative, reimplement virtual void 
*mouseDoubleClickEvent 
<http://doc.trolltech.com/4.3/qwidget.html#mouseDoubleClickEvent>* ( 
QMouseEvent * /event/ ).
Then use indexAt(const QPoint & /point/) and you should get the 
corresponding QModelIndex.
Another (more complicated) way would be to use a QItemDelegate to handle 
everything in each cell as well
as an eventFilter() function. I think that with the first solution you 
should be able to do whatever you want.

Regards,

Alex
