FLTK Window freezing inconsistently
I am trying to simululate "real time" movement of widgets in a window thus the use of the flush method, and basically during this while loop Fl Window will freeze at a random point in the loop, but not every time that the code is run, more like once in 3 times. The window would get Not responding error, and then recover after the loop has finished.
As shown in the code, I tried using lock function thinking that it was the main module trying to interfere, but it yielded no results
Fl::lock();
while (instructions.size() > 0) {
instructions[0]->do_it();
this->redraw();
Sleep(plotSpeed);
Fl::flush();
instructions.erase(instructions.begin());
}
Fl::awake();
Fl::unlock();

I also had issues with this, mostly the behavior was different on OSX and Linux.
But one suggestion: after the Sleep call, also add an Fl::check() call, which should handle all pending internal messages. Alternatively try Fl::wait().
