Details

The Add method is used to add specialized design type instances to the Tree.

Design reusable parts must implement the Prim_Book.iBookDesign interface and inherit from the class specified in the Design property of the Book.

When using the Add method, Tree no longer works like a LANSA list, and is intended for more advanced implementations.

Example

Adding a specialized design type, in this case a page for an Employee data object.

     Mthroutine Name(AddItem) 

Define_Com Class(#prim_Tree.TreeItem) Name(#Item) Reference(*Dynamic)

#Item <= #Tree.Add(#MyEmployeeItem)
#Item.RelatedReference <= #DataEmployee

Endroutine
