<h2 id="details">Detailed Description</h2>
<p>Radial gradients interpolate colors between a focal circle and a center circle in Shape items. Points outside the cone defined by the two circles will be transparent.</p>
<p>Outside the end points the gradient is either padded, reflected or repeated depending on the spread type.</p>
<p>Below is an example of a simple radial gradient. Here the colors are interpolated between the specified point and the end points on a circle specified by the radius:</p>
<pre class="cpp">
fillGradient: RadialGradient {
centerX: <span class="number">50</span>; centerY: <span class="number">50</span>
centerRadius: <span class="number">100</span>
focalX: centerX; focalY: centerY
GradientStop { position: <span class="number">0</span>; color: <span class="string">"blue"</span> }
GradientStop { position: <span class="number">0.2</span>; color: <span class="string">"green"</span> }
GradientStop { position: <span class="number">0.4</span>; color: <span class="string">"red"</span> }
GradientStop { position: <span class="number">0.6</span>; color: <span class="string">"yellow"</span> }
GradientStop { position: <span class="number">1</span>; color: <span class="string">"cyan"</span> }
}
</pre>
<p class="centerAlign"><img src="images/shape-radial-gradient.png" alt="" /></p><p>Extended radial gradients, where a separate focal circle is specified, are also supported.</p>
<p><b>Note: </b><a href="qml-qtquick-shapes-radialgradient.html">RadialGradient</a> is only supported in combination with Shape items. It is not compatible with <a href="qml-qtquick-rectangle.html">Rectangle</a>, as that only supports <a href="qml-qtquick-gradient.html">Gradient</a>.</p><p><b>See also </b>QRadialGradient.</p>
