Subclassing

Note that HelpView may not be subclassed like every other widget in FLTK because fltk::HelpView::draw( ) and fltk::HelpView::handle( ... ) are private. If I subclass them, I lose basic functionality because I cannot access those functions from a child class.

This is a "bug" and I'll report it when I have the time.
