<h2>Function Documentation</h2>

<h3 class="fn" id="qDefaultSurfaceFormat"><a name="qDefaultSurfaceFormat"></a><span class="type">QSurfaceFormat</span> QtDataVisualization::<span class="name">qDefaultSurfaceFormat</span>(<span class="type">bool</span> <i>antialias</i>)</h3>
<p>This convenience function can be used to create a custom surface format suitable for use by Qt Data Visualization graphs.</p>
<p>The <i>antialias</i> parameter specifies whether or not antialiasing is activated.</p>
<p>Give the surface format returned by this function to the graph constructor (C++) or set it as the window format for QQuickView (QML) before calling <code>show()</code> on it.</p>
<p>For example, disable antialiasing on C++ application:</p>
<pre class="cpp">

  <span class="preprocessor">#include &lt;QtDataVisualization/qutils.h&gt;</span>

  <span class="comment">// ...</span>

  <span class="type"><a href="q3dbars.html">Q3DBars</a></span> <span class="operator">*</span>graph <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="q3dbars.html">Q3DBars</a></span>(<span class="type">QtDataVisualization</span><span class="operator">::</span>qDefaultSurfaceFormat(<span class="keyword">false</span>));

</pre>
<p>For example, enable antialiasing for direct rendering modes on QML application:</p>
<pre class="cpp">

  <span class="preprocessor">#include &lt;QtDataVisualization/qutils.h&gt;</span>

  <span class="comment">// ...</span>

  <span class="type">QQuickView</span> viewer;
  viewer<span class="operator">.</span>setFormat(<span class="type">QtDataVisualization</span><span class="operator">::</span>qDefaultSurfaceFormat());

</pre>
<p><b>Note: </b>Antialiasing is not supported in OpenGL ES2 environments.</p><!-- @@@qDefaultSurfaceFormat -->
