In short, I'm thinking: Fl::focus()->window()
Fl::focus() returns the current Fl_Widget with focus (if any),
and Fl_Widget::window() returns the parent window.
Note both Fl::focus() and window() can return NULL,
so check return values first.

I don't know this one, so I'd refer to the docs:
http://fltk.org/doc-1.3/group__fl__windows.html#ga3130407bc1c11f9b7f2a9c43a87a1599
"Returns the first top-level window in the list of shown() windows.
If a modal() window is shown this is the top-most modal window,
otherwise it is the most recent window to get an event."
If it doesn't make sense, try some empirical tests to see.
On some systems, a window can be below others in Z, yet can
have focus and receive events (eg. window managers with
focus-follows-mouse enabled)
