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

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