gestures.</p>
<p>The QGestureEvent 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="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="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>

using gestures in your applications, see the <a href="gestures-overview.html">Gestures Programming</a> document.</p>
<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="QGestureEvent" />QGestureEvent.__init__ (<i>self</i>, unknown-type <i>gestures</i>)</h3><p>Creates new <a href="qgestureevent.html">QGestureEvent</a>
containing a list of <i>gestures</i>.</p>
<h3 class="fn"><a name="QGestureEvent-2" />QGestureEvent.__init__ (<i>self</i>, <a href="qgestureevent.html">QGestureEvent</a>)</h3><h3 class="fn"><a name="accept" />QGestureEvent.accept (<i>self</i>)</h3><p>Accepts the event, the equivalent of calling
setAccepted(true).</p>
<p><b>See also</b> <a href="qevent.html#accept">QEvent.accept</a>().</p>
<h3 class="fn"><a name="accept-2" />QGestureEvent.accept (<i>self</i>, <a href="qgesture.html">QGesture</a>)</h3><p>Sets the accept flag of the given <i>gesture</i> object, the
equivalent of calling <a href="qgestureevent.html#setAccepted">setAccepted(gesture,
true)</a>.</p>
<p>Setting the accept flag indicates that the event receiver wants
the gesture. Unwanted gestures may be propagated to the parent
widget.</p>
<p><b>See also</b> <a href="qgestureevent.html#ignore">QGestureEvent.ignore</a>().</p>
<h3 class="fn"><a name="accept-3" />QGestureEvent.accept (<i>self</i>, <a href="qt.html#GestureType-enum">Qt.GestureType</a>)</h3><p>Sets the accept flag of the given <i>gestureType</i>, the
equivalent of calling <a href="qgestureevent.html#setAccepted">setAccepted(gestureType,
true)</a>.</p>
<p>Setting the accept flag indicates that the event receiver wants
the gesture. Unwanted gestures may be propagated to the parent
widget.</p>
<p><b>See also</b> <a href="qgestureevent.html#ignore">QGestureEvent.ignore</a>().</p>
<h3 class="fn"><a name="activeGestures" />unknown-type QGestureEvent.activeGestures (<i>self</i>)</h3><p>Returns a list of active (not canceled) gestures.</p>
<h3 class="fn"><a name="canceledGestures" />unknown-type QGestureEvent.canceledGestures (<i>self</i>)</h3><p>Returns a list of canceled gestures.</p>
<h3 class="fn"><a name="gesture" /><a href="qgesture.html">QGesture</a> QGestureEvent.gesture (<i>self</i>, <a href="qt.html#GestureType-enum">Qt.GestureType</a> <i>type</i>)</h3><p>Returns a gesture object by <i>type</i>.</p>
<h3 class="fn"><a name="gestures" />unknown-type QGestureEvent.gestures (<i>self</i>)</h3><p>Returns all gestures that are delivered in the event.</p>
<h3 class="fn"><a name="ignore" />QGestureEvent.ignore (<i>self</i>)</h3><p>Ignores the event, the equivalent of calling
setAccepted(false).</p>

<h3 class="fn"><a name="ignore-2" />QGestureEvent.ignore (<i>self</i>, <a href="qgesture.html">QGesture</a>)</h3><p>Clears the accept flag parameter of the given <i>gesture</i>
object, the equivalent of calling <a href="qgestureevent.html#setAccepted">setAccepted(gesture,
false)</a>.</p>
<p>Clearing the accept flag indicates that the event receiver does
not want the gesture. Unwanted gestures may be propagated to the
parent widget.</p>
<p><b>See also</b> <a href="qgestureevent.html#accept">QGestureEvent.accept</a>().</p>
<h3 class="fn"><a name="ignore-3" />QGestureEvent.ignore (<i>self</i>, <a href="qt.html#GestureType-enum">Qt.GestureType</a>)</h3><p>Clears the accept flag parameter of the given
<i>gestureType</i>, the equivalent of calling <a href="qgestureevent.html#setAccepted">setAccepted(gesture,
false)</a>.</p>
<p>Clearing the accept flag indicates that the event receiver does
not want the gesture. Unwanted gestures may be propgated to the
parent widget.</p>
<p><b>See also</b> <a href="qgestureevent.html#accept">QGestureEvent.accept</a>().</p>
<h3 class="fn"><a name="isAccepted" />bool QGestureEvent.isAccepted (<i>self</i>)</h3><p>Returns true is the event has been accepted; otherwise returns
false.</p>
<p><b>See also</b> <a href="qevent.html#accepted-prop">QEvent.accepted</a>.</p>
<h3 class="fn"><a name="isAccepted-2" />bool QGestureEvent.isAccepted (<i>self</i>, <a href="qgesture.html">QGesture</a>)</h3><p>Returns true if the <i>gesture</i> is accepted; otherwise
returns false.</p>
<h3 class="fn"><a name="isAccepted-3" />bool QGestureEvent.isAccepted (<i>self</i>, <a href="qt.html#GestureType-enum">Qt.GestureType</a>)</h3><p>Returns true if the gesture of type <i>gestureType</i> is
accepted; otherwise returns false.</p>
<h3 class="fn"><a name="mapToGraphicsScene" /><a href="qpointf.html">QPointF</a> QGestureEvent.mapToGraphicsScene (<i>self</i>, <a href="qpointf.html">QPointF</a> <i>gesturePoint</i>)</h3><p>Returns the scene-local coordinates if the <i>gesturePoint</i>
is inside a graphics view.</p>
<p>This functional might be useful when the gesture event is
delivered to a <a href="qgraphicsobject.html">QGraphicsObject</a>
to translate a point in screen coordinates to scene-local
coordinates.</p>
<p><b>See also</b> <a href="qpointf.html#isNull">QPointF.isNull</a>() and <a href="index.html">.</a>.</p>
<h3 class="fn"><a name="setAccepted" />QGestureEvent.setAccepted (<i>self</i>, bool <i>accepted</i>)</h3><p>Sets or clears the event's internal flag that determines whether
it should be delivered to other objects.</p>
<p>Calling this function with a value of true for <i>accepted</i>
indicates that the caller has accepted the event and that it should
not be propagated further. Calling this function with a value of
false indicates that the caller has ignored the event and that it
should be delivered to other objects.</p>
<p>For convenience, the accept flag can also be set with <a href="qgestureevent.html#accept">accept</a>(), and cleared with <a href="qgestureevent.html#ignore">ignore</a>().</p>
<p><b>See also</b> <a href="qgestureevent.html#isAccepted">isAccepted</a>() and <a href="qevent.html#accepted-prop">QEvent.accepted</a>.</p>
<h3 class="fn"><a name="setAccepted-2" />QGestureEvent.setAccepted (<i>self</i>, <a href="qgesture.html">QGesture</a>, bool)</h3><p>Sets the accept flag of the given <i>gesture</i> object to the
specified <i>value</i>.</p>
<p>Setting the accept flag indicates that the event receiver wants
the <i>gesture</i>. Unwanted gestures may be propagated to the
parent widget.</p>
<p>By default, gestures in events of type <a href="qevent.html#Type-enum">QEvent.Gesture</a> are accepted, and
gestures in <a href="qevent.html#Type-enum">QEvent.GestureOverride</a> events are
ignored.</p>
<p>For convenience, the accept flag can also be set with <a href="qgestureevent.html#accept">accept</a>(gesture), and cleared with
<a href="qgestureevent.html#ignore">ignore</a>(gesture).</p>
<h3 class="fn"><a name="setAccepted-3" />QGestureEvent.setAccepted (<i>self</i>, <a href="qt.html#GestureType-enum">Qt.GestureType</a>, bool)</h3><p>Sets the accept flag of the given <i>gestureType</i> object to
the specified <i>value</i>.</p>
<p>Setting the accept flag indicates that the event receiver wants
to receive gestures of the specified type, <i>gestureType</i>.
Unwanted gestures may be propagated to the parent widget.</p>
<p>By default, gestures in events of type <a href="qevent.html#Type-enum">QEvent.Gesture</a> are accepted, and
gestures in <a href="qevent.html#Type-enum">QEvent.GestureOverride</a> events are
ignored.</p>
<p>For convenience, the accept flag can also be set with <a href="qgestureevent.html#accept">accept</a>(gestureType), and cleared
