Class XHtmlTarget

java.lang.Object
  net.xoetrope.html.XHtmlTarget

All Implemented Interfaces:

XContentHolder

public class XHtmlTarget
extends java.lang.Object
implements XContentHolder

When using framesets the 'screen' is devided up into a number of different target areas. Each target area may contain a page. The content for each target area is set by naming the target area when calling displayPage. This class provides support for this behaviour by wrapping the Container class to ensure the target area is properly sized. How the target areas are actually laid out depends on the layout manager being used.
