Hi Andrej, >If I understand correctly, you want to catch clicks on the treeview and >then analyse whick mouse button was used? If so, then: No, not the treeview but clicks on the column header, the event at the bottom of http://developer.gnome.org/doc/API/2.0/gtk/GtkTreeViewColumn.html I only see a user_data field, no button info. In fact I'd like to know the shift, control etc. mask too if possible. Thanks, Manuel _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
