Is GtkMethodExpression exist that could call a method to get the value?

[taozuhong]

<object class="GtkLabel">
  <property name="hexpand">TRUE</property>
  <property name="xalign">0</property>
  <binding name="label">
    <method type="gchararray" function="get_name" target="GFileInfo">
      <lookup name="item">GtkListItem</lookup>
    </closure>
  </binding>
</object>

the result is returned by calling method:

 (listitem.item as FileInfo).get_name();

Currently there is no support for that. I think it would be really cool if it GtkBuilder was able to get methods like that using gobject introspection.
