handle_event

This function should be called when the top-level window which contains the search bar received a key event.

If the key event is handled by the search bar, the bar will be shown, the entry populated with the entered text and gdk_event_stop will be returned. The caller should ensure that events are not propagated further.

If no entry has been connected to the search bar, using connect_entry, this function will return immediately with a warning.

}
