Telling the *parent window* to show() should pop it to the front.
I assume by 'stacking order' you mean the stacking order of the window
the TextDisplay is in.

No, I don't think you can determine where your window is in the global
window manager stacking order.. not through FLTK anyway. Possibly
through
the native window manager, but hopefully you don't need to do that. Just
show()ing the window will pop it if it's below other windows, and will
have
no effect if it's already at the top.

By "visible" it means it's not hidden with hide(), and should be visible
unless obscured by other windows.
Window obscuring, TMK, is never considered.
