I think topline() uses size() to determine the max,
so if you use help->topline(help->size() - help->h());
this would probably get you right to the bottom. eg:
#include <FL/Fl_Window.H>
#include <FL/Fl_Help_View.H>
int main(int argc, char *argv[]) {
if ( argc < 2 )
{ fprintf(stderr, "usage: %s /path/to/foo.html\n", argv[0]); exit(1); }
Fl_Window win(300,300);
Fl_Help_View *help;
help = new Fl_Help_View(10,10,300-20,300-20);;
help->load(argv[1]);
help->topline(help->size() - help->h()); // <<<--------------
win.end();
win.resizable(win);
win.show();
Fl::run();
return(0);
}
