<p><a href="qwheelevent.html">QWheelEvent</a>s received by a
<a href="qgraphicsview.html">QGraphicsView</a> are translated into
QGraphicsSceneWheelEvents; it translates the <a href="qwheelevent.html#globalPos">QWheelEvent.globalPos</a>() into
item, scene, and screen coordinates (<a href="qgraphicsscenewheelevent.html#pos">pos</a>(), <a href="qgraphicsscenewheelevent.html#scenePos">scenePos</a>(), and

<hr /><h2>Method Documentation</h2><h3 class="fn"><a name="buttons" /><a href="qt-mousebuttons.html">Qt.MouseButtons</a> QGraphicsSceneWheelEvent.buttons (<i>self</i>)</h3><p>Returns the mouse buttons that were pressed when the wheel event
occurred.</p>

<h3 class="fn"><a name="delta" />int QGraphicsSceneWheelEvent.delta (<i>self</i>)</h3><p>Returns the distance that the wheel is rotated, in eighths
(1/8s) of a degree. A positive value indicates that the wheel was
rotated forwards away from the user; a negative value indicates
that the wheel was rotated backwards toward the user.</p>
<p>Most mouse types work in steps of 15 degrees, in which case the
delta value is a multiple of 120 (== 15 * 8).</p>


<h3 class="fn"><a name="modifiers" /><a href="qt-keyboardmodifiers.html">Qt.KeyboardModifiers</a> QGraphicsSceneWheelEvent.modifiers (<i>self</i>)</h3><p>Returns the keyboard modifiers that were active when the wheel
event occurred.</p>
