Cocos2d-x在windows下实现全屏(cocos2d-x+win32+fullScreen)

本人使用的cocos2dx版本为cocos2d-x_v2.1.5b，之前查到一些解决全屏的办法，但是这些方法对新版本已经不再适用，经过辛苦查询，总算是皇天不负有心人，找到了新版本的解决办法。参考原文：http://www.cocos2d-x.org/forums/6/topics/24432

方法如下：（亲测可行）

1、在目录cocos2dx\platform\win32下找到CCEGLView.h和CCEGLView.cpp，用记事本打开，在CCEGLView.h中添加如下代码

 bool enterFullscreen(int fullscreenWidth=0, int fullscreenHeight=0);
 bool exitFullscreen(int windowX, int windowY, int windowedWidth, int windowedHeight, int windowedPaddingX, int windowedPaddingY);
 int getFullscreenWidth();
 int getFullscreenHeight();

2、在CCEGLView.cpp中添加如下代码

 int CCEGLView::getFullscreenWidth()
 {
     return GetDeviceCaps(m_hDC, HORZRES);
 }

 int CCEGLView::getFullscreenHeight()
 {
     return GetDeviceCaps(m_hDC, VERTRES);
 }

 bool CCEGLView::enterFullscreen(int fullscreenWidth, int fullscreenHeight)
 {
     DEVMODE fullscreenSettings;
     bool isChangeSuccessful;

     if(fullscreenWidth == 0 || fullscreenHeight == 0)
     {
         fullscreenWidth  = GetDeviceCaps(m_hDC, HORZRES);
         fullscreenHeight = GetDeviceCaps(m_hDC, VERTRES);
     }

     int colourBits       = GetDeviceCaps(m_hDC, BITSPIXEL);
     int refreshRate      = GetDeviceCaps(m_hDC, VREFRESH);

     EnumDisplaySettings(NULL, 0, &fullscreenSettings);
     fullscreenSettings.dmPelsWidth        = fullscreenWidth;
     fullscreenSettings.dmPelsHeight       = fullscreenHeight;
     fullscreenSettings.dmBitsPerPel       = colourBits;
     fullscreenSettings.dmDisplayFrequency = refreshRate;
     fullscreenSettings.dmFields           = DM_PELSWIDTH |
                                             DM_PELSHEIGHT |
                                             DM_BITSPERPEL |
                                             DM_DISPLAYFREQUENCY;

     SetWindowLongPtr(m_hWnd, GWL_EXSTYLE, WS_EX_APPWINDOW | WS_EX_TOPMOST);
     SetWindowLongPtr(m_hWnd, GWL_STYLE, WS_POPUP | WS_VISIBLE);
     SetWindowPos(m_hWnd, HWND_TOPMOST, 0, 0, fullscreenWidth, fullscreenHeight, SWP_SHOWWINDOW);
     isChangeSuccessful = ChangeDisplaySettings(&fullscreenSettings, CDS_FULLSCREEN) == DISP_CHANGE_SUCCESSFUL;
     ShowWindow(m_hWnd, SW_MAXIMIZE);

     resize(fullscreenWidth, fullscreenHeight);

     return isChangeSuccessful;
 }

 bool CCEGLView::exitFullscreen(int windowX, int windowY, int windowedWidth, int windowedHeight, int windowedPaddingX, int windowedPaddingY)
 {
     bool isChangeSuccessful;

     SetWindowLongPtr(m_hWnd, GWL_EXSTYLE, WS_EX_LEFT);
     SetWindowLongPtr(m_hWnd, GWL_STYLE, WS_OVERLAPPEDWINDOW | WS_VISIBLE);
     isChangeSuccessful = ChangeDisplaySettings(NULL, CDS_RESET) == DISP_CHANGE_SUCCESSFUL;
     SetWindowPos(m_hWnd, HWND_NOTOPMOST, windowX, windowY, windowedWidth + windowedPaddingX, windowedHeight + windowedPaddingY, SWP_SHOWWINDOW);
     ShowWindow(m_hWnd, SW_RESTORE);

     return isChangeSuccessful;
 }

3、如何使用

在main.cpp中添加

 // Create the application instance
     AppDelegate app;
     CCEGLView* eglView = CCEGLView::sharedOpenGLView();

     // Set the frame size to the full screen value
     //eglView->setFrameSize(eglView->getFullscreenWidth(), eglView->getFullscreenHeight());

     eglView->enterFullscreen(0, 0);

     int ret = CCApplication::sharedApplication()->run();

这样就能够实现全屏了！
