Not able to detect touch events as "TouchBegin" QEvent when Popup object is open.

[Pavankumar S V]

Hello,
I have implemented a code to detect X and Y co-ordinates of the touch points.
In the implementation, I have used eventFilter() to detect the touch events like this:

bool IpcSocket::eventFilter(QObject *,QEvent *event)
{
	qDebug()<<" EVENT TYPE :"<<event->type();

	if(event->type() == QEvent::TouchBegin)
	{
		QList<QTouchEvent::TouchPoint> touchBeginPoints = static_cast<QTouchEvent *>(event)->touchPoints();
		foreach (const QTouchEvent::TouchPoint &touchBeginPoint, touchBeginPoints)
		{
			unsigned int touchX = touchBeginPoint.pos().x();
			unsigned int touchY = touchBeginPoint.pos().y();
			qDebug() << "X :=" << touchX << ", Y :=" << touchY;
		}
	}
	return false;
}

In most cases, whenever the screen is touched, the above eventFilter() function is called with the touch events detected as "TouchBegin" QEvent.
But if a popup is opened and if there is a single touch anywhere on the screen, then the above function is called with the touch event detected as a series of "UpdateRequest" QEvents.
But I want to get the X and Y touch co-ordinates even with the pop up opened. Please help me with the below queries:

1. I want to know why the touch event is not detected as "TouchBegin" QEvent if pop up is opened.
2. Also I wanted to know how to detect the touch events as "TouchBegin" QEvent when popup is opened.
