Yes, for an example of a custom draw() routine in a subclassed widget,
see:
http://seriss.com/people/erco/fltk/#FltkX
http://seriss.com/people/erco/fltk/#AnimateDrawing
..the "void draw()" routines being the one in question.
If you search for 'void draw()' on that page, you'll find
several examples that do this, the first example (FltkX) being
the simplest, and the second (AnimateDrawing) being one that involves
image drawing. The latter has a call to "Fl_Box::draw();" which
is similar to what you were trying to do.
In FLTK there are several situations where you subclass a widget
(Fl_Box, Fl_Window, etc) to gain access to features; the FLTK
draw() method, handle() method, and resize() method, to name a few.
