Dcop implementation results in error

I've been trying to implement DCOP-support into Yammi, but sofar I haven't had any success.

I had some troubles but those were fixed by subclassing my DcopInterface after KMainWindow (I was told to do this on another forum).

But now a new problem has arisen. When I try to compile I get this error:

This is the changes that I've made sofar:

Created an interface which inherits DCOPOBject:

	Source code
1 2 3 4 5 6 7	class YammiDcopIface: virtual public DCOPObject { K_DCOP k_dcop: };

Edited the YammiGui class so that it inherits YammiDcopIface AFTER KMainWindow and added a call to DCOPObject("YammiPlayer") BEFORE the call to KMainWindow() in the Constructor.
