Description

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.

Details

struct GtkSearchBar

struct GtkSearchBar;

gtk_search_bar_new ()

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

gtk_search_bar_connect_entry ()

void                gtk_search_bar_connect_entry        (GtkSearchBar *bar,
                                                         GtkEntry *entry);

Connects the GtkEntry widget passed as the one to be used in this search bar. The entry should be a descendant of the search bar. This is only required if the entry isn't the direct child of the search bar (as in our main example).

bar :

 a GtkSearchBar

entry :

 a GtkEntry

Since 3.10

gtk_search_bar_get_search_mode ()

gboolean            gtk_search_bar_get_search_mode      (GtkSearchBar *bar);

Returns whether the search mode is on or off.

bar :

 a GtkSearchBar

Returns :

 whether search mode is toggled on

Since 3.10

gtk_search_bar_set_search_mode ()

void                gtk_search_bar_set_search_mode      (GtkSearchBar *bar,
                                                         gboolean search_mode);

Switches the search mode on or off.

bar :

 a GtkSearchBar

search_mode :

 the new state of the search mode

Since 3.10

gtk_search_bar_get_show_close_button ()

gboolean            gtk_search_bar_get_show_close_button
                                                        (GtkSearchBar *bar);

Returns whether the close button is shown.

bar :

 a GtkSearchBar

Returns :

 whether the close button is shown

Since 3.10

gtk_search_bar_set_show_close_button ()

void                gtk_search_bar_set_show_close_button
                                                        (GtkSearchBar *bar,
                                                         gboolean visible);

Shows or hides the close button. Applications that already have a "search" toggle button should not show a close button in their search bar, as it duplicates the role of the toggle button.

bar :

 a GtkSearchBar

visible :

 whether the close button will be shown or not

Since 3.10

gtk_search_bar_handle_event ()

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.
