[Qt-interest] Mouse double click.

[Alexandre Beraud]

Hi,

Ok, my bad ! Then the code you sent in an earlier e-mail, using 
sendEvent(), seems good, but you have to construct the virtual mouse 
position yourself. If you have the QModelIndex then you can use the 
visualRect() function of the treeview to get an appropriate coordinate. 
Otherwise you must at least know the row and column of the item.

Regards,

Alex
