Running a keep-alive timer at 5ms while my loop is running with
Fl::wait() has given me the effect I'm looking for with no noticeable
slowdown.
void keepAlive_to(void *)
{
Fl::repeat_timeout(0.005,keepAlive_to);
}
...
Fl::add_timeout(0.005,keepAlive_to);
while ( doSomething() )
Fl::wait();
Fl::remove_timeout(keepAlive_to);
Since this is a learning exercise, I'll have to try your idea too.
Thanks again.
Mike
