<h2 id="details">Detailed Description</h2>
<p><a href="qml-qtquick-patharc.html">PathArc</a> provides a simple way of specifying an arc that ends at a given position and uses the specified radius. It is modeled after the SVG elliptical arc command.</p>
<p>The following QML produces the path shown below:</p>
<div class="table"><table class="generic">
 <tr valign="top" class="odd"><td ><p class="centerAlign"><img src="images/declarative-patharc.png" alt="" /></p></td><td ><pre class="qml">

      }
  }

<p>Note that a single <a href="qml-qtquick-patharc.html">PathArc</a> cannot be used to specify a circle. Instead, you can use two <a href="qml-qtquick-patharc.html">PathArc</a> elements, each specifying half of the circle.</p>
