/**

 * 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).
