1: public:
2: int m_GLPixelIndex;
3: HGLRC m_hGLContext;
2、在视图类的构造函数中对这两个成员进行初始化：
1: m_GLPixelIndex = 0;
2: m_hGLContext = NULL;
3、在视图类声明中添加两个成员函数：
1: BOOL SetWindowPixelFormat(HDC hDC);
2: BOOL CreateViewGLContext(HDC hDC);
4、在视图类的实现文件中添加这两个成员函数的实现：
1: BOOL CXXXView::CreateViewGLContext(HDC hDC)
2: { 3: m_hGLContext = wglCreateContext(hDC);
4:
5: if(m_hGLContext==NULL)
6: return FALSE;
7:
8: if(wglMakeCurrent(hDC,m_hGLContext)==FALSE)
9: return FALSE;
10:
11: return TRUE;
12: }
以及
1: BOOL CXXXView::SetWindowPixelFormat(HDC hDC)
2: { 3: PIXELFORMATDESCRIPTOR pixelDesc;
4:
5: pixelDesc.nSize = sizeof(PIXELFORMATDESCRIPTOR);
6: pixelDesc.nVersion = 1;
7:
8: pixelDesc.dwFlags = PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL |
9: PFD_DOUBLEBUFFER | PFD_STEREO_DONTCARE;
10:
11: pixelDesc.iPixelType = PFD_TYPE_RGBA;
12: pixelDesc.cColorBits = 32;
13: pixelDesc.cRedBits = 8;
14: pixelDesc.cRedShift = 16;
15: pixelDesc.cGreenBits = 8;
16: pixelDesc.cGreenShift = 8;
17: pixelDesc.cBlueBits = 8;
18: pixelDesc.cBlueShift = 0;
19: pixelDesc.cAlphaBits = 0;
20: pixelDesc.cAlphaShift = 0;
21: pixelDesc.cAccumBits = 64;
22: pixelDesc.cAccumRedBits = 16;
23: pixelDesc.cAccumGreenBits = 16;
24: pixelDesc.cAccumBlueBits = 16;
25: pixelDesc.cAccumAlphaBits = 0;
26: pixelDesc.cDepthBits = 32;
27: pixelDesc.cStencilBits = 8;
28: pixelDesc.cAuxBuffers = 0;
29: pixelDesc.iLayerType = PFD_MAIN_PLANE;
30: pixelDesc.bReserved = 0;
31: pixelDesc.dwLayerMask = 0;
32: pixelDesc.dwVisibleMask = 0;
33: pixelDesc.dwDamageMask = 0;
34:
35: m_GLPixelIndex = ChoosePixelFormat(hDC,&pixelDesc);
36: if(m_GLPixelIndex == 0) // Choose default
37: { 38: m_GLPixelIndex = 1;
39: if(DescribePixelFormat(hDC,m_GLPixelIndex,
40: sizeof(PIXELFORMATDESCRIPTOR),&pixelDesc)==0)
41: return FALSE;
42: }
43:
44: if(!SetPixelFormat(hDC,m_GLPixelIndex,&pixelDesc))
45: return FALSE;
46:
47: return TRUE;
48: }
在视图类的OnCreate成员函数中添加：
1: HWND hWnd = GetSafeHwnd();
2: HDC hDC = ::GetDC(hWnd);
3:
4: if(SetWindowPixelFormat(hDC)==FALSE)
5: return -1;
6:
7: if(CreateViewGLContext(hDC)==FALSE)
8: return -1;
添加OnPaint消息响应函数，在函数中加入：
1: HWND hWnd = GetSafeHwnd();
2: HDC hDC = ::GetDC(hWnd);
3: wglMakeCurrent(dc.m_ps.hdc,m_hGLContext);
4:
5: ....
6:
7: // Double buffer
8: SwapBuffers(dc.m_ps.hdc);
9: glFlush();
10:
11: // release
12: ::ReleaseDC(hWnd,hDC);
添加OnSize消息响应函数。这里的内容可以根据需要进行修改：
1: glViewport(0,0,(GLsizei)cx,(GLsizei)cy);
2: glMatrixMode(GL_PROJECTION);
3: glLoadIdentity();
4: gluPerspective(60.0,(GLfloat)cx/(GLfloat)cy,0.1,100.0);
5: glMatrixMode(GL_MODELVIEW);
6: glLoadIdentity();
添加虚函数OnActivateView，在其中添加：
1: HWND hWnd = GetSafeHwnd();
2: HDC hDC = ::GetDC(hWnd);
3: wglMakeCurrent(hDC,m_hGLContext);
4: ::ReleaseDC(hWnd,hDC);
添加WM_DESTROY消息响应函数，在其中添加：
1: if(wglGetCurrentContext() != NULL)
2: wglMakeCurrent(NULL,NULL);
3:
4: if(m_hGLContext != NULL)
5: { 6: wglDeleteContext(m_hGLContext);
7: m_hGLContext = NULL;
8: }
Over。
