virtual

Implements Graph_lib::Widget.

                               {
  // (FLTK работает на int'ах, так что преобразуем)
  ptr_wid = new Fl_Button{int(loc.x), int(loc.y), int(width), int(height),
                          label.c_str()};
  // (великий и ужасный...)
  ptr_wid->callback(reinterpret_cast<Fl_Callback*>(cb), this);
  own = &win;
}
