The objects you write in IDL can, in the vast number of cases, take full advantage of the Export Bridge technology, with only a few of IDL’s capabilities not available. In addition, due to limitations imposed by external environments (COM and Java), certain restrictions exist for the method signatures that are exposed through the Export Bridge. This section outlines these functional limitations.
The section also provides a concise introduction to the object classes available to make drawable wrapper objects (objects that subclass from IDLitWindow, IDLgrWindow, and IDLitDirectWindow) and which to use when, with examples.
