Release 10.1A: OpenEdge Development:
ADM and SmartObjects

Support include files

As noted in Chapter 1, "Overview," a SmartObject template generally includes a single support include file: the primary include file for the class on which the SmartObject is based. This include file has the same name as the template (but a different extension). For example, the SmartDataViewer template viewer.w includes the primary include file viewer.i. A primary include file such as viewer.i does not directly contain most of the code needed to support the SmartObject. It contains only those program elements required to compile a master built from that template:

Any variable or other definitions needed by all masters of that type.
A reference to the next support include file up the chain (for example, a SmartDataViewer is a visual object that displays data, so it includes datavis.i; if there is no other intermediate object above this type, it includes smart.i), and its own property include file, which defines those properties stored in the ADMProps temp-table for the object.
Initialization code in the main block for this object type’s properties and any other generic object startup code.
Any routine that requires compile-time resolution of preprocessors or for some other reason must be part of the master’s compilation unit (.r file).
