C++ interface to ncurses routines
|
|
-----------------------------------------------------------------------
|
|
|
|
This directory contains the source code for several 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 curses.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. It was originally provided by a
|
|
derived class. This caused some trouble if you think about Panels or
|
|
Menus and Forms with colors. We decided to put color support into the
|
|
base class so that any derived class may use color support also.
|
|
The implementation chosen here is directed to unrestricted use
|
|
of mixes of color and monochrome windows. The original NCursesColorWindow
|
|
class is maintained for compatibility reasons.
|
|
|
|
The last point to mention is the support of other packages that are
|
|
distributed with the ncurses package: the panels library, the menu library
|
|
and the form library. This support is provided by the NCursesPanel class,
|
|
which is also derived from the NCursesWindow class and the NCursesMenu
|
|
and NCursesForm classes which are derived from NCursesPanel. 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.
