<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="angle-2"></a><a href="qtglobal.html#qreal-typedef">qreal</a> QLineF::angle ( const QLineF & <i>line</i> ) const</h3>
<p>Returns the angle (in degrees) between this line and the given <i>line</i>, taking the direction of the lines into account. If the lines do not intersect within their range, it is the intersection point of the extended lines that serves as origin (see <a href="qlinef.html#IntersectType-enum">QLineF::UnboundedIntersection</a>).</p>
<p><table class="generic" align="center" cellpadding="2" cellspacing="1" border="0">
<tr valign="top" class="odd"><td><img src="images/qlinef-angle-identicaldirection.png" /></td><td><img src="images/qlinef-angle-oppositedirection.png" /></td></tr>
</table></p>
<p>When the lines are parallel, this function returns 0 if they have the same direction; otherwise it returns 180.</p>
