Simple answer: don't just single-click the triangle but keep the mouse button pressed while moving down over the popup list. Complex answer: you are referring to some very fundamental GTK+ behaviour. To my knowledge, this behaviour can't be changed easily, not even by themes. I think there should be a chance to manually highlight list items when the mouse moves over them (without any mouse button being pressed) by intercepting certain signals. I haven't tried this and it's generally not advisable to attempt this, for about 4 reasons: 1. you would need to program this non-standard behaviour for every single combobox of your application, 2. the behaviour of other GTK+ applications wouldn't change by this, 3. this different behaviour between your and other GTK+ applications would most certainly irritate users, 4. the change in behaviour appears to be so fractional that apparently noone else considered a change of the standard behaviour (or even complained about it) as yet. An always open alternative for you would be to (re)write your own CustomCombobox widget. Then you can implement exactly the behaviour (and look) you intend. But again, this would most certainly irritate more people than being regarded a benefit. Not to mention the amount of time you would have to spend for this. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
