The code was originally derived from the libg++ CursesWindow class, but rewritten 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. For example, you do not 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.
