Catch EVT_RIGHT_UP and call event.Skip() for normal processing. Calling
virtual functions like this is discouraged and may not continue to work in
the future for all platforms.

C++ requires you to subclass and override all virtual functions. The
speed/size overhead to do this for all classes/functions would be enormous
so wxLua only does this where absolutely necessary.
