/* graphwin.h -- Borland graphics.h replacement for Windows
*
* haftmann#software FREEWARE 12/02
* This file is under development and may work or not. Tested with Windows XP
* Requires Borland C++ 3.1, 4.0 or 4.5 to compile happily!
*
: You should modify your #include <graphics.h> to
:
: #ifdef _Windows
: # include "graphwin.h"
: #else
: # include <graphics.h>
: #endif
:
: and without*) any further changes your program will compile both
: for DOS and Windows.
: (But you should disable the linker warning: "warn duplicate symbols".)
: *) You should insert some calls to yield() when you make lengthy
: calculations, printing jobs etc. to keep Windows alive meanwhile.
: See hint below for mouse access. There is no general solution.
*
* Why you may want to switch to Windows using graphwin.h?
* + You tried Borland's EASYWIN library, but it is not graphical
* + Same try, but you have no access to cursor and function keys
* + You have much more, easy addressable memory in Windows (=DPMI)
* - Your screen does flicker in DOS (56 Hz)
* + Your program is able to run in a window (and you hate monitor blackouts)
* + You want to stay at the OEM (DOS) character set (technical symbols etc.)
* + You can move step-by-step to a true Windows application,
* most programmers may replace their self-made file open/save hassle
* by GetOpenFileName() / GetSaveFileName() at next - and don't forget to
* #define OFN_LONGNAMES 0x200000
* and some extra OemToAnsi() / AnsiToOem() calls with its struct!
*
* Hint:
* Mouse access routines must be changed from Int33 to Windows
* GetCursorPos() and GetKeyState() functions! The good news:
* You don't need functions like MouseShow() and MouseHide() anymore.
*
* Known Bugs:
* Almost everywhere are bugs: This library is simply NOT THROUGHOUTLY TESTED
* Drawing functions seem to be bug-free with some differences in appearance,
* but some seldom used functions like restorecrtmode() may not work at all.
