This non-instantiable class is the superclass of all stream classes
onto which graphics can be drawn. This includes windows (instances of basic-pane
and its
subclasses), the screen (whose class is screen
), bitmap-stream
, and
printer
streams. The class may be useful for specializing methods that should
apply to any stream on which graphics can be drawn.
A diagram of window and widget classes is shown in Widget and window classes in cgide.htm.
