@class wxDelegateRendererNative
wxDelegateRendererNative allows reuse of renderers code by forwarding all the
- wxRendererNative methods to the given object and thus allowing you to only
- modify some of its methods -- without having to reimplement all of them.
+ wxRendererNative methods to the given object and
+ thus allowing you to only modify some of its methods -- without having to
+ reimplement all of them.
Note that the "normal", inheritance-based approach, doesn't work with the
renderers as it is impossible to derive from a class unknown at compile-time
by using this class.
Except for the constructor, it has exactly the same methods as
- wxRendererNative and their implementation is trivial: they are simply forwarded
- to the real renderer. Note that the "real" renderer may, in turn, be a
- wxDelegateRendererNative as well and that there may be arbitrarily many levels
- like this -- but at the end of the chain there must be a real renderer which
- does the drawing.
