Description | ODWin32WindowCanvas is an Win-specific SOM class that encapsulates onscreen dynamic drawing contexts. The ODWin32WindowCanvas class is derived from ODWin32Canvas and wraps a device context. It can be instantiated directly as a result of the ODWin32Canvas::CreateConcreteCanvas or ODPlatformCanvas::CreateConcreteCanvas factory methods. This class overrides nearly all of the methods of ODWin32Canvas. Because ODWin32WindowCanvas does not introduce any methods, it can be referred to using a pointer to an ODWin32Canvas.
Methods | p. ODWin32WindowCanvas defines no new methods.
