+ * @Short_description: A container which can hide its child
+ * @Title: GtkExpander
+ *
+ * A #GtkExpander allows the user to hide or show its child by clicking
+ * on an expander triangle similar to the triangles used in a #GtkTreeView.
+ *
+ * Normally you use an expander as you would use any other descendant
+ * of #GtkBin; you create the child widget and use gtk_container_add()
+ * to add it to the expander. When the expander is toggled, it will take
+ * care of showing and hiding the child automatically.
+ *
+ * <refsect2 id="expander-special-usage">
+ * <title>Special Usage</title>
+ * <para>
+ * There are situations in which you may prefer to show and hide the
+ * expanded widget yourself, such as when you want to actually create
+ * the widget at expansion time. In this case, create a #GtkExpander
+ * but do not add a child to it. The expander widget has an
+ * #GtkExpander:expanded property which can be used to monitor
+ * its expansion state. You should watch this property with a signal
+ * connection as follows:
+ * </para>
+ * <informalexample>
+ * <programlisting id="expander-callback-example">
+ * expander = gtk_expander_new_with_mnemonic ("_More Options");
+ * g_signal_connect (expander, "notify::expanded",
+ * G_CALLBACK (expander_callback), NULL);

+ * expander_callback (GObject *object,
+ * GParamSpec *param_spec,
+ * gpointer user_data)

+ *
+ * expander = GTK_EXPANDER (object);
+ *
+ * if (gtk_expander_get_expanded (expander))
+ * {
+ * /* Show or create widgets */
+ * }

+ * <para>
+ * The GtkExpander implementation of the GtkBuildable interface
+ * supports placing a child in the label position by specifying
