                  C++ interface to ncurses routines
-----------------------------------------------------------------------

This directory contains the source code for three C++ classes which
ease the use of writing ncurses-based programs.  The code is derived
from the libg++ CursesWindow class but enhanced for ncurses.

The classes simplify the use of window specific functions by
encapsulating them in the window object.  Function overloading is
used in order to narrow the interface.  E.g. you don't have the
distinction between `printw' and `mvprintw' anymore.

A second benefit is the removal of all #defines which are included in
the ncurses.h file.  This is a steady cause of trouble because many
common identifiers are used.  Instead now all #defines are inline
functions which also allows strict type checking of arguments.

The next enhancement is color support, which is provided by a derived
class.  The implementation chosen here is directed to unrestricted use
of mixes of color and monochrome windows.  This is done through virtual
functions and means that you can write all of your code as if a color
window is the destination.  If the destination window is monochrome these
functions calls have no effect.

	NOTE: This implementation of the color support was topic of
	some discussion.  The introduction of virtual functions
	introduced some overhead.  Please let us know what you think
	about this: is it worth being able to write color supporting
	functions.

The last point to mention is the support of another package Zeyd
distributes with his ncurses package: the panels library.  This support
is provided by the NCursesPanel class, which is also derived from the
NCursesWindow class.  This allows building interfaces with windows.
Please see the example program for a quick introduction.

Note that at this point, there is no documentation for these classes.
Hopefully some will be written in the not too distant future.  For now,
to find out how to use the classes, read the code and the example program.

Suggestions for enhancements and contributions of code (and docs) are
welcome.  Please let us know which functionality you miss.

	ATTENTION LINUX USERS:  There is currently some discussion of
	replacing the BSD curses in the Linux libc with ncurses.  If
	this is done we could perhaps include these classes in the Linux
	libg++ replacing the original CursesWindow class (and renaming it
	to CursesWindow).  This could be done because NCursesWindow can
	be made easily to a superset of the CursesWindow class.
