template <typename RealType, typename HandleAs> int registerMetaType()

Registers the type RealType with the metatype system.

This method can take a second template parameter to specify a cast that should be invoked during registration. This is useful if a base type is already supported.

   class SomeType
   {
   public:
     QString someProp() const;
   };

   // define some introspectable API for SomeType

   KTEXTTEMPLATE_BEGIN_LOOKUP(SomeType)
     if (property == "someProp")
       return object.someProp();
   KTEXTTEMPLATE_END_LOOKUP


   class OtherType : public SomeType
   {
     // ...
   };

   registerMetaType<SomeType>();

   // Only the introspectable API from SomeType is needed, so we can reuse that
 registration.
   registerMetaType<OtherType, SomeType>();
