Why not; what is preventing you?
If it's because you don't have access to 'brow' because of the
variable's scope, either make it a global, or pass it as userdata
to the callback from main().

"Run the window"?
Not sure what you mean, can you clarify?
When a callback is invoked, you do what you need to do
in that function, creating/manipulating the widgets, whatever.
When you return from the callback, the Fl::run() loop will
regain control.
If you're trying to access the window from the callback and can't
because of the window's variable scope, change the scope by either
making it a global, or passing a pointer to it as userdata to the
callback.

I think if I show you a clean example, you'll get a better idea
of how it works.

What prevents you?
Make it a global and then you can change it from anywhere in
the app, and your popen() command can access it.

My guess is you've got a problem with variable scope, and just need to
make
brow a global, so that you can access it from wherever you end up
putting
your popen() command.
I'll try to follow up with a rewrite of your app, so that you can get
an idea of how it should be laid out. Shouldn't be hard.
