;

}



如果是URL文件，调用OpenURLMovie，该函数跟OpenLocalMovie区别主要在于不用NewMovieFromFile而用NewMovieFromDataRef来得到句柄。



     一般电影在创建完Movie Controller后最好调用PrePrerollMovie。

void CQuickTime::CreateNewMovieController(HWND hwnd, Movie theMovie, MovieController *theMC)

{

     ……

PrePrerollMovie(theMovie, GetMovieTime(theMovie, NULL), GetMoviePreferredRate(theMovie), NewMoviePrePrerollCompleteProc(QTPrePrerollCompleteProc), (void *)m_hViewWnd);

}



3.2.3关闭电影

     void CQuickTime::CloseMovie(void)

{

    if (m_MC)

    {

        DisposeMovieController(m_MC);

    }

         if (m_Movie)

          {

              DisposeMovie(m_Movie);

          }

          m_Movie = NULL;

          m_MC = NULL;

}



3.2.4建立和取消电影窗口关联

int CQuickTime::OnMovieWindowCreate(HWND hWnd, CREATESTRUCT *lpCreateStruct)

{



     if ( hWnd != NULL)

     {

          m_hViewWnd = hWnd;                     // the view''s hwnd

         

         // Create GrafPort <-> HWND association

          CreatePortAssociation(m_hViewWnd, NULL, kQTMLHandlePortEvents);  

     }



     return 0;

}

void CQuickTime::OnMovieWindowDestroy()

{

     if(m_Movie)

          AbortPrePrerollMovie(m_Movie,noErr);

     



     CGrafPtr     windowPort = NULL;

     

     // close any movies   before destroying PortAssocation

     CloseMovie();



     // Destroy the view''s GrafPort <-> HWND association

     if (m_hViewWnd)

          windowPort = (CGrafPtr)GetHWNDPort(m_hViewWnd);

     

     if (windowPort)

          DestroyPortAssociation(windowPort);



}



3.2.5控制电影播放

笔者用控制MCDoAction来控制播放，这样可以得到播放的状态，当然也可以调用StartMovie、StopMovie等api函数。例如，

void CQuickTime::Play()

{

if(m_Mov
