/**
* gtk_search_bar_handle_event:
* @bar: a #GtkSearchBar
* @event: a #GdkEvent containing key press events
*
* 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
* gtk_search_bar_connect_entry(), this function will return
* immediately with a warning.
*
* ## Showing the search bar on key presses
*
* |[<!-- language="C" -->
* static gboolean
* on_key_press_event (GtkWidget *widget,

* }
*
* g_signal_connect (window,
* "key-press-event",
* G_CALLBACK (on_key_press_event),
* search_bar);

*
* Returns: %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.
