<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qgestureevent.html">QGestureEvent</a> class provides the description of triggered gestures.</p>
<p>The <a href="qgestureevent.html">QGestureEvent</a> class contains a list of gestures, which can be obtained using the <a href="qgestureevent.html#gestures">gestures</a>() function.</p>
<p>The gestures are either active or canceled. A list of those that are currently being executed can be obtained using the <a href="qgestureevent.html#activeGestures">activeGestures</a>() function. A list of those which were previously active and have been canceled can be accessed using the <a href="qgestureevent.html#canceledGestures">canceledGestures</a>() function. A gesture might be canceled if the current window loses focus, for example, or because of a timeout, or for other reasons.</p>
<p>If the event handler does not accept the event by calling the generic <a href="../qtcore/qevent.html#accept">QEvent::accept</a>() function, all individual <a href="qgesture.html">QGesture</a> object that were not accepted and in the <a href="../qtcore/qt.html#GestureState-enum">Qt::GestureStarted</a> state will be propagated up the parent widget chain until a widget accepts them individually, by calling <a href="qgestureevent.html#accept">QGestureEvent::accept</a>() for each of them, or an event filter consumes the event.</p>
