I'll give a little more detail... Right now I have these non-generic types:
t_point = class f_left, f_top : longint; // so named for descendents // several fields and methods to manage it as I need end; t_box = class (t_point) f_width, f_height : longint; // more fields and methods to manage it as I need end; They've been great. Now I have need for a point and box that use real coordinates. The structure would be identical -- simply replacing "longint" with "single" -- which is why I thought generics would be perfect. However, t_box inherits from t_point, and this appears to be a sticking point. My code looks like this: generic gt_point<_num> = class f_left, f_top : _num; // other fields, methods end; generic gt_box<_t_point,_num> = class (_t_point) f_width, f_height : _num; // other fields, methods end; t_real_point = specialize gt_point<single>; t_real_box = specialize gt_box<t_real_point,single>; Thanks all! ~David. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
