handle_event


Description:

public bool handle_event (Event event)

Handles 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 [[email protected]_entry], this function will return immediately with a warning.

Showing the search bar on key presses

```c static gboolean on_key_press_event (GtkWidget *widget, GdkEvent *event, gpointer user_data) { HdySearchBar *bar = HDY_SEARCH_BAR (user_data); return hdy_search_bar_handle_event (self, event); }

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

// Add more widgets to the window...

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

Parameters:

this

a search bar

event

a [[email protected]] containing key press events

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.
