多点触摸第一个MFC程序

一.运行条件:

WIN7系统,WIN7 SDK v7.0,VS2008

二.添加多点触摸代码:

(1)在***View.h中添加几个手势有关的数据成员和成员函数:

POINT _ptFirst;        // first significant point of gesture

    POINT _ptSecond;       // second significant point of gesture

    DWORD _dwID;      // current ID

ULONGLONG _dwArguments;    // this is holder for additional information about gesture event

 

注:以下函数都在***View.cpp中:

(2) 初始化InitGesture():

//初始化手势,以使窗口能响应手势事件

void ChdHomeMDIView::GST_InitGesture()

{

    //初始化手势

    GESTURECONFIG config = { 0 };

    config.dwWant = GC_ROTATE;//支持旋转

    config.dwID = GID_ROTATE;

    config.dwBlock = 0;

 

    SetGestureConfig(

        GetSafeHwnd(),

        0,

        1,

        &config,

        sizeof(GESTURECONFIG)

        );

 

    config.dwID = GID_PAN;//支持单点鼠标移动,并且设置阻塞一个手指的单击并移动否则不能响应鼠标单击WM_LBUTTONDOWN和鼠标移动
