Agreeing with what Ian said, I would add that it sounds like
only your app knows about the window associations (ie. which
is the 'master' and which are the 'subs')
It sounds to me it would be necessary for your 'master'
window to keep track of the subs by maintaining an array
of pointers to them.
It'd be best if your master window was a derived class from Fl_Window,
and have your own hide() method that runs hide() on all the windows
in your array, as well as calling Fl_Window::hide() to hide the main
one.
