This wouldn't work for me because I need to keep calling Fl::run(). My
program takes commands from a pipe (in a second thread) which tells it
to show/hide and what to display. If I don't call Fl::run() then the
pipe thread won't be able to tell the main thread to show itself.
So, the logic is:
- Create main window
- Hide it
- Create pipe thread
- Pipe thread Fl::awake()'s the main thread
- perhaps show/hide the main window
- display what we're told to via the pipe
- repeat until told to quit
For now, my solution is the while(!quit) version of FL::run().
while (!quit) Fl::wait(1e20);
I'm using Fl::wait(1e20) because calling Fl::run() in this loop would
just result in a 100% cpu process when the main window was hidden.
