That is true, but it shouldn't have anything to do with subclassing. That just means that you can't add a Window to another container (except a Display).
Most of the tutorial examples use this approach - for example: http://svn.apache.org/repos/asf/pivot/trunk/tutorials/src/org/apache/pivot/tutorials/buttons/PushButtons.java http://svn.apache.org/repos/asf/pivot/trunk/tutorials/src/org/apache/pivot/tutorials/buttons/push_buttons.bxml If you want to create a component that you can use within another container, you'll need to extend a different class. Maybe BoxPane or TablePane?
