26 * SECTION:hildon-banner
27 * @short_description: A widget used to display timed notifications.
29 * #HildonBanner is a small, pop-up window that can be used to display
30 * a short, timed notification or information to the user. It can
31 * communicate that a task has been finished or that the application
34 * Hildon provides convenient funtions to create and show banners. To
35 * create and show information banners you can use
36 * hildon_banner_show_information(), hildon_banner_show_informationf()
37 * or hildon_banner_show_information_with_markup().
39 * If the application window has set the _HILDON_DO_NOT_DISTURB flag (using
40 * hildon_gtk_window_set_do_not_disturb() for example), the banner will not
41 * be shown. If you need to override this flag for important information,
42 * you can use the method hildon_banner_show_information_override_dnd().
43 * Please, take into account that this is only for important information.
46 * Two more kinds of banners are maintained for backward compatibility
47 * but are no longer recommended in Hildon 2.2. These are the animated
48 * banner (created with hildon_banner_show_animation()) and the
49 * progress banner (created with hildon_banner_show_progress()). See
50 * hildon_gtk_window_set_progress_indicator() for the preferred way of
51 * showing progress notifications in Hildon 2.2.
53 * Information banners dissapear automatically after a certain
54 * period. This is stored in the #HildonBanner:timeout property (in
55 * miliseconds), and can be changed using hildon_banner_set_timeout().
57 * Note that #HildonBanner<!-- -->s should only be used to display
58 * non-critical pieces of information.
