GtkCombo does not send signal

[Pramod Patangay <pramod patangay gmail com>]

Hi,

I am using GTK 2.4 and facing a problem with GtkCombo. I populated a
GtkCombo with entries. I want to catch signals when the selection
changes. I am handling "changed" signal on the combo. I would like to
know even if the selection was not changed but the user popped up the
combo and selected the already selected entry. In this case "changed"
signal is not emitted. How do I achieve this? Is there some other
signal for this?

Also how to I programmatically set the focus to combo.
gtk_widget_grab_focus fails.

Thanks
