/**
 * 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.
 *
 * Special Usage
 *
 * 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
 * "expanded" property which can be used to monitor
 * its expansion state. You should watch this property with a signal
 * connection as follows:
 *
 * $(DDOC_COMMENT example)
 *
 * <hr>
 *
 * GtkExpander as GtkBuildable
 *
 * The GtkExpander implementation of the GtkBuildable interface
 * supports placing a child in the label position by specifying
 * "label" as the "type" attribute of a &lt;child&gt; element.
 * A normal content child can be specified without specifying
 * a &lt;child&gt; type attribute.
 *
 * $(DDOC_COMMENT example)
