org.dvb.application.plugins.XletContainer
This class provides a container that can be embedded in a widget hierarchy, and can provide a container that can safely be used as the top-level container of an embedded Xlet. This solves the problem of an embedded Xlet being able to call getParent() to discover the widget hierarchy in which it is embedded.
