<h2 id="details">Detailed Description</h2>
<p><a href="qml-qtlocation-mappinchevent.html">MapPinchEvent</a> type provides basic information about pinch event. They are present in handlers of MapPinch (for example pinchStarted/pinchUpdated). Events are only guaranteed to be valid for the duration of the handler.</p>
<p>Except for the <a href="qml-qtlocation-mappinchevent.html#accepted-prop">accepted</a> property, all properties are read-only.</p>
