【编程】WinCE 左键长按消息的处理

在窗口处理函数中：

 

case   WM_LBUTTONDOWN： 

    { 
      SHRGINFO   shrg; 
      shrg.cbSize   =   sizeof(shrg); 
      shrg.hwndClient   =   m_hWnd; 
      shrg.ptDown.x   =   LOWORD(lParam); 
      shrg.ptDown.y   =   HIWORD(lParam); 
      shrg.dwFlags   =   SHRG_RETURNCMD; 

      CPoint   point; 
      point.x   =   shrg.ptDown.x; 
      point.y   =   shrg.ptDown.y; 

      if(::SHRecognizeGesture(&shrg)   ==   GN_CONTEXTMENU)//长按键消息 
            { 
                     <<事件处理程序>>

            } 

}
