In the constructor I call this function and it initializes certain members. Now I derived another class and there I defined the virtual function as well, to override the original one. Now I call the constructor from the derived class and it in turn calls the virtual function, but the problem is that the called function is not the one that overrides it. Instead it calls the function of the base class. Maybe I missunderstand something here, but I thought that when I decalre a function as virtual always the overriding function is called unless I specify :: explicitly. Is this a missbehaving of the compiler or is this correct? How can I achive that a overiding function is called? The base class shouldn't and doesn't know about classes that overrides it but what good is a virtual function when it doesn't get called? --- [ comp.std.c++ is moderated.
