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 <Juergen.Pfeifer@T-Online.de> diff --git a/lib/libcurses++/cursesapp.cc b/lib/libcurses++/cursesapp.cc new file mode 100644 index 00000000000..503de0936cf --- /dev/null +++ b/lib/libcurses++/cursesapp.cc @@ -0,0 +1,146 @@ +// * this is for making emacs happy: -*-Mode: C++;-*- +/**************************************************************************** + * Copyright (c) 1998 Free Software Foundation, Inc. * + * * + * Permission is hereby granted, free of charge, to any person obtaining a * + * copy of this software and associated documentation files (the * + * "Software"), to deal in the Software without restriction, including * + * without limitation the rights to use, copy, modify, merge, publish, * + * distribute, distribute with modifications, sublicense, and/or sell * + * copies of the Software, and to permit persons to whom the Software is * + * furnished to do so, subject to the following conditions: * + * * + * The above copyright notice and this permission notice shall be included * + * in all copies or substantial portions of the Software. * + * * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS * + * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * + * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. * + * IN NO EVENT SHALL THE ABOVE COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, * + * DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR * + * OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR * + * THE USE OR OTHER DEALINGS IN THE SOFTWARE. * + * * + * Except as contained in this notice, the name(s) of the above copyright * + * holders shall not be used in advertising or otherwise to promote the * + * sale, use or other dealings in this Software without prior written * + * authorization. * + ****************************************************************************/ + +/**************************************************************************** + * Author: Juergen Pfeifer <Juergen.Pfeifer@T-Online.de> 1997 * + ****************************************************************************/ + +#include "cursesapp.h" +#include "internal.h" + +MODULE_ID("$Id: cursesapp.cc,v 1.1 1999/05/09 00:21:14 millert Exp $") + +void +NCursesApplication::init(bool bColors) { + if (bColors) + NCursesWindow::useColors(); + + if (Root_Window->colors() > 1) { + b_Colors = TRUE; + Root_Window->setcolor(1); + Root_Window->setpalette(COLOR_YELLOW,COLOR_BLUE); + Root_Window->setcolor(2); + Root_Window->setpalette(COLOR_CYAN,COLOR_BLUE); + Root_Window->setcolor(3); + Root_Window->setpalette(COLOR_BLACK,COLOR_BLUE); + Root_Window->setcolor(4); + Root_Window->setpalette(COLOR_BLACK,COLOR_CYAN); + Root_Window->setcolor(5); + Root_Window->setpalette(COLOR_BLUE,COLOR_YELLOW); + Root_Window->setcolor(6); + Root_Window->setpalette(COLOR_BLACK,COLOR_GREEN); + } + else + b_Colors = FALSE; + + Root_Window->bkgd(' '|window_backgrounds()); +} + +NCursesApplication* NCursesApplication::theApp = 0; +NCursesWindow* NCursesApplication::titleWindow = 0; +NCursesApplication::SLK_Link* NCursesApplication::slk_stack = 0; + +NCursesApplication::~NCursesApplication() { + Soft_Label_Key_Set* S; + + delete titleWindow; + while( (S=top()) ) { + pop(); + delete S; + } + delete Root_Window; + ::endwin(); +} + +int NCursesApplication::rinit(NCursesWindow& w) { + titleWindow = &w; + return OK; +} + +void NCursesApplication::push(Soft_Label_Key_Set& S) { + SLK_Link* L = new SLK_Link; + assert(L); + L->prev = slk_stack; + L->SLKs = &S; + slk_stack = L; + if (Root_Window) + S.show(); +} + +bool NCursesApplication::pop() { + if (slk_stack) { + SLK_Link* L = slk_stack; + slk_stack = slk_stack->prev; + delete L; + if (Root_Window && top()) + top()->show(); + } + return (slk_stack ?
