|
wxRenderer class is used to draw all wxWindows controls. This is an ABC and
|
|
the look of the application is determined by the concrete derivation of
|
|
wxRenderer used in the program.
|
|
|
|
It also contains a few static methods which may be used by the concrete
|
|
renderers and provide the functionality which is often similar or identical
|
|
in all renderers (using inheritance here would be more restrictive as the
|
|
given concrete renderer may need an arbitrary subset of the base class
|
|
methods)
