使用Borland的C ++图形 [英] Graphics in C++ using Borland
问题描述
目前我正在使用Borland的C ++
（ http://www.borland.com/products/down...cbuilder.html# ）
我想要能够获取一系列点并在屏幕上绘制它们。
有办法做到这一点吗？例如。我希望能够绘制一个函数。在这个
点，我没有达到C ++的水平，我想开始学习Visual C ++
所以我不想走那条路。
谢谢

嗨Pmb（皮特），
你提到过，
"我希望能够获得一系列积分
并在屏幕上绘制它们。
你需要创建一个窗口然后获得
该窗口的设备常量HDC。
你还需要一支笔，HPEN。
注意，这是一个Win32项目，而不是一个控制台项目。
下面是一些代码片段这可能会对你有所帮助。
长__stdcall
WinProc（HWND Wnd，uint WM，uint wp，long lp）{
return DefWindowProc（Wnd，WM，wp，lp）; }
int __stdcall WinMain（HINSTANCE inst，
HINSTANCE PID，LPSTR CmdLn，int x1）{
HPEN Pen = CreatePen（PS_SOLID，0，RGB（255,0,0））;
HBRUSH Black = CreateSolidBrush（RGB（0,0,0））;
{WNDCLASS Class = {
0，WinProc，0,0，PID，0,0，Black，0，" WinProc" };
RegisterClass（& Class）; }
int Left_Scr，Top_Scr，W_Me，H_Me，Right_Scr，Bot_Scr;
{long R [4];
SystemParametersInfo （
SPI_GETWORKAREA，0，（RECT *）R，0）;
Right_Scr = R [2]; Bot_Scr = R [3];
R [2] - = R [0]; R [3] - = R [1];
Left_Scr = R [0]; Top_Scr = R [1];
W_Me = R [2]; H_Me = R [3]; }
HWND Win = CreateWindow" WinProc"，" Some Title"，
WS_VISIBLE，Left_Scr，Top_Scr，
W_Me，H_Me，0,0，PID，0）;
HDC DC = GetDC（Win）;
int x，y;
MoveToEx（DC，x = 100，y = 200,0）;
LineTo（DC，x = 200，y = 300）;
ReleaseDC（Win，DC）;
MSG Msg;
while（GetMessage（& Msg，0,0,0）{
TranslateMessage（& Msg）; DispatchMessage（& Msg）;
unsigned int M = Msg.message，C = Msg.wParam;
if（M == WM_KEYDOWN&& C == 27）返回1;
}
}

这不是主题，因为我想学习如何用C ++做这件事。

At the moment I''m using Borland''s C++
(http://www.borland.com/products/down...cbuilder.html#)
I want to be able to take an array of points and plot them on the screen. Is
there a way to do this? E.g. I want to be able to graph a function. At this
point I''m not up to a level in C++ where I want to start learning Visual C++
so I don''t want to go that route.
Thanks

Hi Pmb ( Pete ),
You mentioned,
" I want to be able to take an array of points
and plot them on the screen. "
You need to create a window and then get
the device constant, HDC, of that window.
You also need a pen, HPEN.
Note, this is a Win32 project, not a console project.
Below are a few code snippets that might help you.
long __stdcall
WinProc ( HWND Wnd, uint WM, uint wp, long lp ) {
return DefWindowProc( Wnd, WM, wp,lp ); }
int __stdcall WinMain ( HINSTANCE inst,
HINSTANCE PID, LPSTR CmdLn, int x1 ) {
HPEN Pen = CreatePen( PS_SOLID, 0, RGB( 255, 0, 0 ) );
HBRUSH Black = CreateSolidBrush ( RGB( 0, 0, 0 ) );
{ WNDCLASS Class = {
0, WinProc, 0, 0, PID, 0, 0, Black, 0, "WinProc" };
RegisterClass( & Class ); }
int Left_Scr, Top_Scr, W_Me, H_Me, Right_Scr, Bot_Scr ;
{ long R[ 4 ];
SystemParametersInfo(
SPI_GETWORKAREA, 0, ( RECT * ) R, 0 );
Right_Scr = R [ 2 ]; Bot_Scr = R [ 3 ];
R [ 2 ] -= R [ 0 ]; R[ 3 ] -= R [ 1 ];
Left_Scr = R [ 0 ]; Top_Scr = R [ 1 ];
W_Me = R [ 2 ]; H_Me = R [ 3 ]; }
HWND Win = CreateWindow "WinProc", "Some Title",
WS_VISIBLE, Left_Scr, Top_Scr,
W_Me, H_Me, 0, 0, PID, 0 );
HDC DC = GetDC( Win );
int x, y ;
MoveToEx ( DC , x = 100, y = 200, 0 );
LineTo ( DC, x = 200, y = 300 );
ReleaseDC( Win, DC);
MSG Msg;
while ( GetMessage( & Msg, 0,0,0) {
TranslateMessage( & Msg ); DispatchMessage( & Msg );
unsigned int M = Msg.message, C = Msg.wParam ;
if ( M == WM_KEYDOWN && C == 27) return 1;
}
}

It''s not off topic since I want to learn how to do this in C++.
