55 * @short_description: Report important messages to the user
57 * @see_also: #GtkStatusbar, #GtkMessageDialog
59 * #GtkInfoBar is a widget that can be used to show messages to
60 * the user without showing a dialog. It is often temporarily shown
61 * at the top or bottom of a document. In contrast to #GtkDialog, which
62 * has a horizontal action area at the bottom, #GtkInfoBar has a
63 * vertical action area at the side.
65 * The API of #GtkInfoBar is very similar to #GtkDialog, allowing you
66 * to add buttons to the action area with gtk_info_bar_add_button() or
67 * gtk_info_bar_new_with_buttons(). The sensitivity of action widgets
68 * can be controlled with gtk_info_bar_set_response_sensitive().
69 * To add widgets to the main content area of a #GtkInfoBar, use
70 * gtk_info_bar_get_content_area() and add your widgets to the container.
72 * Similar to #GtkMessageDialog, the contents of a #GtkInfoBar can by
73 * classified as error message, warning, informational message, etc,
74 * by using gtk_info_bar_set_message_type(). GTK+ uses the message type
75 * to determine the background color of the message area.

110 * The GtkInfoBar implementation of the GtkBuildable interface exposes
111 * the content area and action area as internal children with the names
112 * "content_area" and "action_area".
115 * GtkInfoBar supports a custom <action-widgets> element, which
116 * can contain multiple <action-widget> elements. The "response"
117 * attribute specifies a numeric response, and the content of the element
118 * is the id of widget (which should be a child of the dialogs @action_area).
