itself already derives from XComponent (like e.g. awt::XWindow

still abstract. Using this macro in the most derived class
definition provides overrides for the XComponent methods,
forwarding them to the given baseclass.

Name of the class this macro is issued within
@param baseclass
Name of the baseclass that should have the XInterface methods
forwarded to - that's usually the WeakComponentImplHelperN base
@param implhelper

forwarded to - in the case of the WeakComponentImplHelper,
that would be ::cppu::WeakComponentImplHelperBase
