If you ever need to call another widget's draw method from within your own draw
method, e.g. for an embedded scrollbar, you must downcast the embedded widget's
pointer to Fl_Widget* and call the virtual draw() method.
Fl_Widget *s = &scroll; // scroll is an embedded Fl_Scrollbar
s->draw(); // calls Fl_Scrollbar::draw()
(end of quote)
Just a minor nit. I believe the term "downcast" means something
like "use of a cast operator to convert from a base class to
a derived class pointer or reference." I don't think the example
shows a cast, and if it did it would be an upcast.
I'd suggest "... you must assign the embedded widget's pointer ..."
Best,
Stan
