先来创建一个黑色的窗口吧，作为GL的容器。
Light3dWinAPP 这个类来处理窗口的创建和销毁以及分发 系统事件。
/***********************File:Light3dWinAPP.h;*Author:chenpeng*Data:2015/07/21;*/#include<Windows.h>#include<tchar.h>namespace Light3d{class Light3dWinAPP{public :HINSTANCE m_hInstance;//实例句柄;HWND m_hWnd;//窗口句柄;int m_width;//宽度;int m_height;//高度;public:Light3dWinAPP(HINSTANCE hInstance) :m_hInstance(hInstance){//想要建立一个窗口，必须有一个窗口类;WNDCLASSEX winClass;//窗口类名;winClass.lpszClassName = _T("Light3dWinAPP");winClass.cbSize = sizeof(winClass);//当H 水平方向，V 竖直方向 大小变化或移动时，重绘窗口，//为该类中的每一个窗口分配一个唯一的设备上下文;winClass.style = CS_HREDRAW | CS_VREDRAW | CS_OWNDC;//指向函数的长指针lp,处理窗口的消息循环;winClass.lpfnWndProc = wndProc;//实例句柄;winClass.hInstance = hInstance;//窗口最小化图标;winClass.hIcon = 0;winClass.hIconSm = 0;//鼠标光标;winClass.hCursor = LoadCursor(hInstance, IDC_ARROW);//窗口背景色;winClass.hbrBackground = (HBRUSH)GetStockObject(BLACK_BRUSH);//窗口菜单;winClass.lpszMenuName = nullptr;winClass.cbClsExtra = 0;winClass.cbWndExtra = 0;RegisterClassEx(&winClass);}virtual ~Light3dWinAPP(){UnregisterClass(_T("CELLWinAPP"), m_hInstance);}protected:static LRESULT CALLBACK wndProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam){Light3dWinAPP* pThis = (Light3dWinAPP*)GetWindowLong(hWnd, GWL_USERDATA);if (pThis){return pThis->onEvent(hWnd, msg, wParam, lParam);}if (WM_CREATE == msg){CREATESTRUCT* pCreate = (CREATESTRUCT*)lParam;SetWindowLong(hWnd, GWL_USERDATA,(DWORD_PTR)pCreate->lpCreateParams);}return DefWindowProc(hWnd, msg, wParam, lParam);}public://窗口事件;virtual LRESULT onEvent(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam){switch (msg){case WM_CLOSE:case WM_DESTROY:{::PostQuitMessage(0);}break;case WM_MOUSEMOVE:break;case WM_LBUTTONDOWN:break;case WM_LBUTTONUP:break;case WM_RBUTTONDOWN:break;case WM_RBUTTONUP:break;case WM_KEYDOWN:{switch (wParam){case VK_LEFT:{}break;case VK_RIGHT:break;case VK_UP:break;default:break;}}break;case WM_KEYUP:break;default:return DefWindowProc(hWnd, msg, wParam, lParam);}return S_OK;}//主函数;int main(int width, int height){//创建窗口;m_hWnd = CreateWindowEx(NULL,_T("Light3dWinAPP"),_T("Light3D"),WS_OVERLAPPEDWINDOW,CW_USEDEFAULT,CW_USEDEFAULT,width,height,NULL,NULL,m_hInstance,this);if (m_hWnd == 0){return -1;}ShowWindow(m_hWnd, SW_SHOW);MSG msg = { 0 };while (msg.message!=WM_QUIT){if (msg.message == WM_DESTROY || msg.message == WM_CLOSE){//跳出，退出;break;}//有消息的时候处理消息，，没有消息的时候进行渲染绘制;if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)){TranslateMessage(&msg);DispatchMessage(&msg);}else{//渲染;Sleep(1);}}return 0;}};}
main.cpp 中处理Win的入口函数
/***********************File:main.cpp;*Author:chenpeng*Data:2015/07/21;*/#include "Light3dWinAPP.h"int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow){UNREFERENCED_PARAMETER(hInstance);UNREFERENCED_PARAMETER(hPrevInstance);UNREFERENCED_PARAMETER(lpCmdLine);UNREFERENCED_PARAMETER(nCmdShow);Light3d::Light3dWinAPP app(hInstance);app.main(800, 600);}
