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. + + +Original author: + Eric Newton <newton@rocky.oswego.edu> for FSF's libg++ + +Authors of first ncurses based release (NCursesWindow, NCursesPanel): + Ulrich Drepper <drepper@ira.uka.de> + and Anatoly Ivasyuk <anatoly@nick.csh.rit.edu> + +Author of this release: + Juergen Pfeifer http://www.familiepfeifer.de/Contact.aspx?Lang=en |
