Is TsLib required on Windows?

[pratyaksh]

I am using Qt 4.8.4 version and trying to simulate touch events on windows.
Is it possible to simulate touch events as shown below or some more steps has to be performed apart from this?
QTest::touchEvent(widgetObj,QTouchEvent::TouchScreen).press(0,p1,widgetObj);
QTest::touchEvent(widgetObj,QTouchEvent::TouchScreen).release(0,p1,widgetObj);

Also used setAttribute(Qt::WA_AcceptTouchEvents,true);

Is TsLib required to simulate touch event on windows?
What are the steps involved to Install TsLib on windows?

Thanks,
Pratyaksh
