/**
 * #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 action area at the bottom, #GtkInfoBar has an 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+ may use the message type
 * to determine how the message is displayed.
 * 
 * A simple example for using a GtkInfoBar:
 * |[<!-- language="C" -->
 * // set up info bar
 * GtkWidget *widget;
 * GtkInfoBar *bar;
 * 
 * widget = gtk_info_bar_new ();
 * bar = GTK_INFO_BAR (bar);
 * 
 * gtk_widget_set_no_show_all (widget, TRUE);
 * message_label = gtk_label_new ("");
 * gtk_widget_show (message_label);
 * content_area = gtk_info_bar_get_content_area (bar);
 * gtk_container_add (GTK_CONTAINER (content_area),
 * message_label);
 * gtk_info_bar_add_button (bar,
 * _("_OK"),
 * GTK_RESPONSE_OK);
 * g_signal_connect (bar,
 * "response",
 * G_CALLBACK (gtk_widget_hide),
 * NULL);
 * gtk_grid_attach (GTK_GRID (grid),
 * widget,
 * 0, 2, 1, 1);
 * 
 * ...
 * 
 * // show an error message
 * gtk_label_set_text (GTK_LABEL (message_label), message);
 * gtk_info_bar_set_message_type (bar,
 * GTK_MESSAGE_ERROR);
 * gtk_widget_show (bar);
 * ]|
 * 
 * # GtkInfoBar as GtkBuildable
 * 
 * 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”.
 * 
 * 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).
 * 
 * # CSS nodes
 * 
 * GtkInfoBar has a single CSS node with name infobar. The node may get
 * one of the style classes .info, .warning, .error or .question, depending
 * on the message type.
