Method

GtkSearchBarhandle_event

since: 3.10

Declaration [src]

gboolean
gtk_search_bar_handle_event (
  GtkSearchBar* bar,
  GdkEvent* event
)

Description [src]

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

{
  GtkSearchBar *bar = GTK_SEARCH_BAR (user_data);
  return gtk_search_bar_handle_event (bar, event);
}

static void
create_toplevel (void)
{
  GtkWidget *window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  GtkWindow *search_bar = gtk_search_bar_new ();

 // Add more widgets to the window...

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