Once a friend was writing a cross-platform plugin to a major third party
commercial GUI app, and wanted to use FLTK to post dialog (a file
browser).
The app used its own GUI toolkit, and he didn't want to take chances
destabilizing the main app by having the two gui toolkits compete for
the window manager events and whatnot.
I helped him set it up where we made a small FLTK app that opened the
file browser to the dir his app wanted, and then read back whatever
the user picked. No sockets involved, just stdin/stdout pipes and
command line flags. I think we used popen() across both platforms,
but it's so long ago, I can't remember the details. I believe it was
pretty easy, but that might be the fog of time..
