@franz: yes, that onData function is being called, and yes, i could make the function virtual... but thats not really how i am trying to design this project. there will be multiple signal/slot connections and I dont want to force any receiver classes to have to implement and override the virtual function in the base class.

@marcvanriet: that is a good suggestion, but I do believe this type of signal/slot connection works. when an instance of the baseclass is created, so is an instance of the receiver class. 'this' object should include both the receiver class and any class it inherites from. otherwise, i should be seeing some compile/runtime error telling me it doesnt know what signal i am using to connect the slot.
