   4 //      A simple example of Fl_Text_Editor
   5 //
   6 //      Fl_Text_Editor is unlike other FLTK widgets in that
   7 //      to work correctly, it must be assigned to an instance of an
   8 //      Fl_Text_Buffer.  The below shows using buffer() to connect
   9 //      the two classes together.
  10 //
  11 //      Note that the example can also be used to demonstrate
  12 //      Fl_Text_Display; just replace all instances of
  13 //      Fl_Text_Editor with Fl_Text_Display and rebuild.
