The *FilterModels had a number of of virtual functions, which only accessed members of the base class. Moreover, these functions were identical and generated with macros. Therefore, move these functions to the base class. The one excption is data(), which uses different count functions (passed as a macro parameter). Thus, introduce a virtual countDives() function and likewise move data() to the base class. A function pointer might be even more clear, but since the rest of the code/Qt relies heavily on runtime polymorphism, let's do the same here. The only macros left are those creating the singleton accessors. This could be more clearly realized by templates, but let's likewise keep it the way is.
