+
+        When using the ::cppu::WeakComponentImplHelper base classes to
+        implement a UNO interface, a problem occurs when the interface
+        itself already derives from XComponent (like e.g. awt::XWindow
+        or awt::XControl): ::cppu::WeakComponentImplHelper is then
+        still abstract. Using this macro in the most derived class
+        definition provides overrides for the XComponent methods,
+        forwarding them to the given baseclass.
+
+        @param classname
+        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
+        Name of the baseclass that should have the XComponent methods
+        forwarded to - in the case of the WeakComponentImplHelper,
+        that would be ::cppu::WeakComponentImplHelperBase
