Is very good thanks
Now I'm trying to intercept the signals for combo,but Ive only intercept the enter key
I would also know which are the signals emitted when I'm navigating into the list . Is it possible?
Enteresting is also the other example "autocompletion entry"
Ciao

The only signal available for GtkComboBox is "changed".
The popup window from GtkComboBox is a temporary window. The problem is that there's no method to get hold of the id to this temporary window.
If you want to be able to detect the button that open the pull down menu, and the signals for key up and key down while navigating into the treeview, you will need to use the orignal solution that you have presented.
Have extended your code to a more complete sample code:
