GtkSearchBar is a container made to have a search entry (possibly with additional connex widgets, such as drop-down menus, or buttons) built-in. The search bar would appear when a search is started through typing on the keyboard, or the application's search mode is toggled on.
For keyboard presses to start a search, events will need to be forwarded
from the top-level window that contains the search bar. See
gtk_search_bar_handle_event()
for example code. Common shortcuts such as Ctrl+F
should be handled as an application action, or through the menu items.
You will also need to tell the search bar about which entry you are
using as your search entry using gtk_search_bar_connect_entry()
.
The following example shows you how to create a more complex
search entry.

bar = gtk_search_bar_new (); /<!---->* Create a box for the search entry and related widgets *<---->/ entry = gtk_search_entry_new (); box = gtk_box_new (GTK_ORIENTATION_HORIZONTAL, 6); gtk_box_pack_start (GTK_BOX (box), entry, TRUE, TRUE, 0); /<!---->* Add a menu button to select the category of the search *<---->/ menu_button = gtk_menu_button_new (); gtk_box_pack_start (GTK_BOX (box), menu_button, FALSE, FALSE, 0); gtk_container_add (GTK_CONTAINER (searchbar), box); /<!---->* And tell the search bar about the search entry *<---->/ gtk_search_bar_set_search_entry (GTK_SEARCH_BAR (bar), entry); |
GtkWidget * gtk_search_bar_new (void
);
Creates a GtkSearchBar. You will need to tell it about
which widget is going to be your text entry using
gtk_search_bar_set_entry()
.
Returns : |
a new GtkSearchBar |
Since 3.10
gboolean gtk_search_bar_handle_event (GtkSearchBar *bar
,GdkEvent *event
);
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.
Example 59. Showing the search bar on key presses

static gboolean window_key_press_event_cb (GtkWidget *widget, GdkEvent *event, gpointer user_data) { return gtk_search_bar_handle_event (GTK_SEARCH_BAR (user_data), event); } g_signal_connect (window, "key-press-event", G_CALLBACK (window_key_press_event_cb), search_bar); |
|
a GtkSearchBar |
|
a GdkEvent 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. |
Since 3.10
