2011-05-10Last round of simplification of Signal/Slot classesPavel Labath1-39/+31
- merged all the common stuff from 0,1,2,3 argument versions into one common base class - removed ReturnType template parameter as it was instantiated with "void" everywhere and the current ignores the return value of the callbacks anyway
2011-05-10Simplify Slot.hhPavel Labath1-232/+43
Replace CallbackHolder, FunctorHolder and SlotHolder with a (smaller) set of polymorphic classes. SignalHolder now stores a (smart) pointer to the class.
