+ * SECTION:gtkinfobar
+ * @short_description: Report important messages to the user
+ * @include: gtk/gtk.h
+ * @see_also: #GtkStatusbar, #GtkMessageDialog
+ *
+ * #GtkInfoBar is a widget that can be used to show messages to
+ * the user without showing a dialog. It is often temporarily shown
+ * at the top or bottom of a document. In contrast to #GtkDialog, which
+ * has a horizontal action area at the bottom, #GtkInfoBar has a
+ * vertical action area at the side.
+ *
+ * The API of #GtkInfoBar is very similar to #GtkDialog, allowing you
+ * to add buttons to the action area with gtk_info_bar_add_button() or
+ * gtk_info_bar_new_with_buttons(). The sensitivity of action widgets
+ * can be controlled with gtk_info_bar_set_response_sensitive().
+ * To add widgets to the main content area of a #GtkInfoBar, use
+ * gtk_info_bar_get_content_area() and add your widgets to the container.
+ *
+ * Similar to #GtkMessageDialog, the contents of a #GtkInfoBar can by
+ * classified as error message, warning, informational message, etc,
+ * by using gtk_info_bar_set_message_type(). GTK+ uses the message type
+ * to determine the background color of the message area.
+ *
+ * <example>
+ * <title>Simple GtkInfoBar usage.</title>
+ * <programlisting>
+ * /* set up info bar */
+ * info_bar = gtk_info_bar_new ();
+ * gtk_widget_set_no_show_all (info_bar, TRUE);
+ * message_label = gtk_label_new ("");
+ * gtk_widget_show (message_label);
+ * content_area = gtk_info_bar_get_content_area (GTK_INFO_BAR (info_bar));
+ * gtk_container_add (GTK_CONTAINER (content_area), message_label);
+ * gtk_info_bar_add_button (GTK_INFO_BAR (info_bar),
+ * GTK_STOCK_OK, GTK_RESPONSE_OK);
+ * g_signal_connect (info_bar, "response",
+ * G_CALLBACK (gtk_widget_hide), NULL);
+ * gtk_table_attach (GTK_TABLE (table),
+ * info_bar,
+ * 0, 1, 2, 3,
+ * GTK_EXPAND | GTK_FILL, 0,
+ * 0, 0);
+ *
+ * /* ... */
+ *
+ * /* show an error message */
+ * gtk_label_set_text (GTK_LABEL (message_label), error_message);
+ * gtk_info_bar_set_message_type (GTK_INFO_BAR (info_bar),
+ * GTK_MESSAGE_ERROR);
+ * gtk_widget_show (info_bar);
+ * </programlisting>
+ * </example>
+ *
+ * <refsect2 id="GtkInfoBar-BUILDER-UI">
+ * <title>GtkInfoBar as GtkBuildable</title>
+ * <para>
+ * The GtkInfoBar implementation of the GtkBuildable interface exposes
+ * the content area and action area as internal children with the names
+ * "content_area" and "action_area".
+ * </para>
+ * <para>
+ * GtkInfoBar supports a custom <action-widgets> element, which
+ * can contain multiple <action-widget> elements. The "response"
+ * attribute specifies a numeric response, and the content of the element
+ * is the id of widget (which should be a child of the dialogs @action_area).
