So to be 'clean' I have to Set/GetAttrs() on the object pointer? Since I am deriving from gadgetclass do I have to use SetGadgetAttrs() instead of SetAttrs()? BTW, when I redefine a method for my subclass I have always to call DoSuperMethod() before my own code or my subclass can stick with my code whithout executing the code of the previous classes? Thanx in advance
