<h2>Detailed Description</h2>
<p>该QGraphicsRotation类提供围绕给定轴的旋转变换。</p>
<p>您可以通过分配提供所需的轴<a href="qvector3d.html" tppabs="http://pyqt4doc.appspot.com/qvector3d.html">QVector3D</a>该轴属性或者通过一个成员，如果<a href="qt.html#Axis-enum" tppabs="http://pyqt4doc.appspot.com/qt.html#Axis-enum">Qt.Axis</a>到setAxis方便的功能。默认情况下，该轴为（0 ，0，1 ），即，围绕Z轴旋转。</p>
<p>角特性，这是由QGraphicsRotation提供，现在描述了围绕该轴旋转的度数。</p>
<p>QGraphicsRotation提供某些参数，以帮助控制如何旋转应该被应用。</p>
<p>原点是该项目围绕其旋转（即，它保持固定的相对于父作为产品的其馀部分被转动）的位置。默认情况下，原点是<a href="qpointf.html" tppabs="http://pyqt4doc.appspot.com/qpointf.html">QPointF</a>（0 ，0）。</p>
<p>角属性提供的度数为围绕原点的项目按顺时针方向旋转。该值也可以是负的，表示逆时针旋转。对于动画的目的，也可能是有用的，以提供旋转角度超过（ -360 ， 360 ）度，例如以动画如何项目旋转几次。</p>
<p>注意：最后一次旋转是在三维空间中的旋转后投影回2D的综合效应。如果几个旋转是连续进行的，他们不会像预期的那样，除非他们都绕Z轴。</p>
