gtktreeview selection signals

[Daniele Speziani <daniele speziani phitecingegneria it>]

Hi all,

I've a little problem with mouse/keyboard selection on treeview. In my 
application the user may select a treeview field ( MULTIPLE_SELECTION ) 
by mouse click or cursor change. The problem is that if I change my 
selection by using the up-down keys the "cursor_change" signal is 
emitted and when the selection is done with mouse click both 
"button_release_event" and "cursor_change" signal are emitted. In this 
last case two callbacks are executed. I would like to know if is there a 
way to emit just one signal or if I am usign the wrong signals for my 
purpose.

Thanks
Daniele
