SearchBar.handleEvent

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.types.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 gtk.search_bar.SearchBar.connectEntry, this function will return immediately with a warning.
