- * 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).
- * </para>
