<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qgraphicsscenemouseevent.html">QGraphicsSceneMouseEvent</a> class provides mouse events in the graphics view framework.</p>
<p>When a <a href="qgraphicsview.html">QGraphicsView</a> receives a <a href="../qtgui/qmouseevent.html">QMouseEvent</a>, it translates it to a <a href="qgraphicsscenemouseevent.html">QGraphicsSceneMouseEvent</a>. The event is then forwarded to the <a href="qgraphicsscene.html">QGraphicsScene</a> associated with the view. If the event is not handled by the scene, the view may use it, e.g&#x2e;, for the <a href="qgraphicsview.html#DragMode-enum">DragMode</a>.</p>
<p>In addition to containing the item, scene, and screen coordinates of the event (as <a href="qgraphicsscenemouseevent.html#pos">pos</a>(), <a href="qgraphicsscenemouseevent.html#scenePos">scenePos</a>(), and <a href="qgraphicsscenemouseevent.html#screenPos">screenPos</a>()), mouse events also contain the coordinates of the previous mouse event received by the view. These can be retrieved with <a href="qgraphicsscenemouseevent.html#lastPos">lastPos</a>(), <a href="qgraphicsscenemouseevent.html#lastScreenPos">lastScreenPos</a>(), and <a href="qgraphicsscenemouseevent.html#lastScenePos">lastScenePos</a>().</p>
