/**
  \class Fl_File_Input
  \brief This widget displays a pathname in a text input field.

  A navigation bar located above the input field allows the user to
  navigate upward in the directory tree.
  You may want to handle FL_WHEN_CHANGED events for tracking text changes
  and also FL_WHEN_RELEASE for button release when changing to parent dir.
  FL_WHEN_RELEASE callback won't be called if the directory clicked 
  is the same that the current one.

  \note As all Fl_Input derived objects, Fl_File_Input may call its callback
  when loosing focus (see FL_UNFOCUS) to update its state like its cursor shape.
  One resulting side effect is that you should call clear_changed() early in your callback
  to avoid reentrant calls if you plan to show another window or dialog box in the callback.
