I have two (possibly related) questions:
	1) What does "virtual" mean when you subclass like this:
		class MyClass : virtual public TheirClass { ...

	2) When I try to compile a test program which embeds an
OPPart in a MainWindow I get (I've made a stripped-down example
for myself from the code in embed2):
	myopapp.cpp:59: cannot allocate an object of type
`::MyModule::MyPart' 
	myopapp.cpp:59:  since the following virtual
functions are abstract: 
	myopapp.cpp:59:  void ::KOM::Base::connect(const
char *, class ::KOM::Base *, const char *) 
	myopapp.cpp:59:  void ::KOM::Base::disconnect(const char *, class
::KOM::Base *, const char *)

	and the list goes on and on.

Thanks for the help so far and TIA for more!

Dave
