I was trying to do my components based on the FLTK lib, but I figured out that
the major of the components don't have virtual methods, so there is not way to
do a secure inheritance. If, for instance, I specialize Fl_Widget to intercept
some events by overriding int handle(int) method, and the user somehow calls
the method by using a pointer to the basic class(Fl-Widget), I will have a not
desired behavior. Is there a reason to have the classes this way(call speed?)
and how the people are doing to specialize these classes(besides rewriting the
fltk code, that I don't think is a good idea for maintenance)?
Thanks,
J.Marcelo Auler
