Specifying the Structure Frame Set as a Frame Itself

A common usage of the WsyStructure pattern will be to call the StructureFrameSet function from another Frame Set function.  In this way the Structure frame set will itself be a frame within a parent frame set.  See the documentation of the FrameSetPageGenerator pattern for more details.

Extending the Link Entity

In many situations, the inherited Link entity will need to be extended in different ways including:

• Specifying a list sequence and/or an active code to control the order and contents of the generated Node list.  In this case, it will be necessary to modify the key definition of the Link.ByParentChild view or to specify a new view.  It will also be necessary to update the Windows GUI functions in order to be able to update the new Link fields.
• Inheritance from the _StructureHierarchy, _StructureWithType, and/or _StructureKnowledge patterns in order to enhance or specialize the structure functionality.

Extending the Link entity also means that it is necessary to extend certain call parameters in the Tree, TreeGrid, and ChildGrid UI functions (double-click on the AllFusion Plex warning messages to get to the relevant call statements).
