Yes, you can do
For(;;) {
Fl::wait(0.0); // not Fl::check()!
do_stuff();
}
But that has a bunch of issues.
You can also do Fl::add_idle() which calls you other calculation every time
when there is nothing else to do for FLTK. This will eat up 100% of your CPU
though!
Without know what exacty you calculate, creating an entirely seperte thread
for your calculations seems to be the way to go.

No, redraw() can be called anywhere and any time fro any widget (assuming
the widget exists, of course). It can be called quite often without much
impact on performance. You can even call redraw() from another thread. All
it does is tell FLTK to refresh the widget as soon as it hits the next
Fl::run() or Fl::flush().
