Description | ODOS2WindowCanvas is an OS2-specific SOM class that encapsulates onscreen dynamic drawing contexts. The ODOS2WindowCanvas class is derived from ODOS2Canvas and wraps a presentation space. It can be instantiated directly as a result of the ODOS2Canvas::CreateConcreteCanvas or ODPlatformCanvas::CreateConcreteCanvas factory methods. This class overrides nearly all of the methods of ODOS2Canvas. Because ODOS2WindowCanvas does not introduce any methods, it can be referred to using a pointer to an ODOS2Canvas.
Methods | The ODOS2WindowCanvas class defines no new methods.
