Fl_Browser, and all the vrowser selection types (select, multi) are all exactly
the same. Only the type() filed is set differently. Just use Fl_Browser
everywhere and you are fine. dynamic_cast<Fl_Select_Browser *>(w) of course
returns NULL because the class is Fl_Browser with type() set.
Sorry, it's in the history o FLTK/FL/Forms.
