<h2>Detailed Description</h2>
<p><b>The PinchEvent element was added in QtQuick 1.1</b></p>
<p>The <tt>center</tt>, <tt>startCenter</tt>, <tt>previousCenter</tt> properties provide the center position between the two touch points.</p>
<p>The <tt>scale</tt> and <tt>previousScale</tt> properties provide the scale factor.</p>
<p>The <tt>angle</tt>, <tt>previousAngle</tt> and <tt>rotation</tt> properties provide the angle between the two points and the amount of rotation.</p>
<p>The <tt>point1</tt>, <tt>point2</tt>, <tt>startPoint1</tt>, <tt>startPoint2</tt> properties provide the positions of the touch points.</p>
<p>The <tt>accepted</tt> property may be set to false in the <tt>onPinchStarted</tt> handler if the gesture should not be handled.</p>
