mfc实现播放器功能，双击全屏，再双击还原

视频播放器的制作，视频流在静态控件上显示，类似迅雷看看双击全屏操作的实现

在主窗口的 .h 文件中
[cpp]
BOOL m_isFullScreen;
CRect m_Old;
BOOL PreTranslateMessage(MSG* pMsg);

nbsp;afx_msg void OnDoubleStatic(UINT nFlags,CPoint point); //双击静态控件（显示视频）响应函数

.cpp文件中
[cpp]
//定义消息相应
ON_STN_DBLCLK(IDC_STATIC_VIDEOWND,OnDoubleStatic) ON_STN_DBLCLK(IDC_STATIC_VIDEOWND,OnDoubleStatic)

//在主窗口 .cpp 文件中的初始化函数中先获取原始的位置
m_videoWnd.GetWindowRect(&m_Old);
ScreenToClient(&m_Old);

在主窗口 .cpp 文件中
[cpp]
//
void CTestVoxCVSA_DemoDlg::OnDoubleStatic(UINT nFlags,CPoint point)
{
    CTestVoxCVSA_DemoDlg* m_pDemoDlg = (CTestVoxCVSA_DemoDlg*)AfxGetApp()->m_pMainWnd;
    if (m_isFullScreen == FALSE)
    {
        CWnd *saveParent=m_videoWnd.GetParent();
        m_videoWnd.SetParent(GetDesktopWindow());
        CRect rect;
        GetDesktopWindow()-> GetWindowRect(&rect);
        m_videoWnd.SetWindowPos(&wndTopMost,rect.left,rect.top,rect.right,rect.bottom,SWP_SHOWWINDOW);
        m_pDemoDlg->ShowWindow(SW_HIDE);
        m_isFullScreen = TRUE;
    }
    CDialog::OnLButtonDblClk(nFlags,point);
}

//获取消息的函数
BOOL CTestVoxCVSA_DemoDlg::PreTranslateMessage(MSG* pMsg)
{
    CTestVoxCVSA_DemoDlg* m_pDemoDlg = (CTestVoxCVSA_DemoDlg*)AfxGetApp()->m_pMainWnd;
    if ((pMsg->message==WM_LBUTTONDBLCLK)&&(m_isFullScreen == TRUE))
    {
        m_pDemoDlg->ShowWindow(SW_SHOW);
        m_videoWnd.SetParent(m_pDemoDlg);
        m_videoWnd.SetWindowPos(&wndTop,m_Old.left,m_Old.top,m_Old.right-m_Old.left,m_Old.bottom-m_Old.top,SWP_SHOWWINDOW);
        m_isFullScreen = FALSE;
        return TRUE;
    }
    return CWnd::PreTranslateMessage(pMsg);
}
