gtk-search-bar-handle-event (search-bar event)

search-bar -- a gtk-search-bar widget
event -- a gdk-event containing key press events

+gdk-event-stop+ if the key press event resulted in text being entered in the search entry, and revealing the search bar if necessary, +gdk-event-propagate+ otherwise.

This function should be called when the toplevel 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 the function gtk-search-bar-connect-entry, this function will return immediately with a warning. Showing the search bar on key presses
