<h3 class="fn" id="angle-1"><a name="angle-1"></a><span class="type"><a href="qtglobal.html#qreal-typedef">qreal</a></span> QLineF::<span class="name">angle</span>(const <span class="type"><a href="qlinef.html#QLineF">QLineF</a></span> &<i>line</i>) const</h3>
<p>This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.</p>
<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>
<div class="table"><table class="generic">
<tr valign="top" class="odd"><td ><img src="images/qlinef-angle-identicaldirection.png" alt="" /></td><td ><img src="images/qlinef-angle-oppositedirection.png" alt="" /></td></tr>
</table></div>
<p>When the lines are parallel, this function returns 0 if they have the same direction; otherwise it returns 180.</p>
