<h2 id="available-styles">Available Styles</h2>
<p>Qt Quick Controls 2 comes with a selection of styles.</p>
<a name="default-style"></a>
<h3 >Default Style</h3>
<p class="centerAlign"><img src="images/qtquickcontrols2-default-thumbnail.png" alt="" /></p><p>The <a href="qtquickcontrols2-default.html">Default Style</a> is a simple and light-weight all-round style that offers the maximum performance for Qt Quick Controls 2.</p>
<a name="material-style"></a>
<h3 >Material Style</h3>
<p class="centerAlign"><img src="images/qtquickcontrols2-material-thumbnail.png" alt="" /></p><p>The <a href="qtquickcontrols2-material.html">Material Style</a> offers an appealing design based on the <a href="https://www.google.com/design/spec/material-design/introduction.html">Google Material Design Guidelines</a>, but requires more system resources than the Default style.</p>
<a name="universal-style"></a>
<h3 >Universal Style</h3>
<p class="centerAlign"><img src="images/qtquickcontrols2-universal-thumbnail.png" alt="" /></p><p>The <a href="qtquickcontrols2-universal.html">Universal Style</a> offers an appealing design based on the <a href="https://dev.windows.com/design">Microsoft Universal Design Guidelines</a>, but requires more system resources than the Default style.</p>
<a name="using-styles-in-qt-quick-controls-2"></a>
<h2 id="using-styles-in-qt-quick-controls-2">Using Styles in Qt Quick Controls 2</h2>
<p>In order to run an application with a specific style, either configure the style using <a href="qquickstyle.html">QQuickStyle</a> in C++, pass a command line argument, or set an environment variable. Alternatively, the preferred style and style-specific attributes can be specified in a configuration file.</p>
<p>The priority of these approaches follows the order they are listed below, from highest to lowest. That is, using <a href="qquickstyle.html">QQuickStyle</a> to set the style will always take priority over using the command line argument, for example.</p>
<a name="using-qquickstyle-in-c"></a>
<h3 >Using QQuickStyle in C++</h3>
<p><a href="qquickstyle.html">QQuickStyle</a> provides C++ API for configuring a specific style. The following example runs a Qt Quick Controls 2 application with the Material style:</p>
<pre class="cpp">

  <span class="type"><a href="qquickstyle.html">QQuickStyle</a></span><span class="operator">::</span>setStyle(<span class="string">&quot;Material&quot;</span>);

</pre>
<p>See the detailed description of <a href="qquickstyle.html">QQuickStyle</a> for more details.</p>
<a name="command-line-argument"></a>
<h3 >Command line argument</h3>
<p>Passing a <code>-style</code> command line argument is the convenient way to test different styles. It takes precedence over the other methods listed below. The following example runs a Qt Quick Controls 2 application with the Material style:</p>
<pre class="cpp">

  <span class="operator">.</span><span class="operator">/</span>app <span class="operator">-</span>style material

</pre>
<a name="environment-variable"></a>
<h3 >Environment variable</h3>
<p>Setting the <code>QT_QUICK_CONTROLS_STYLE</code> environment variable can be used to set a system-wide style preference. It takes precedence over the configuration file mentioned below. The following example runs a Qt Quick Controls 2 application with the Universal style:</p>
<pre class="cpp">

  QT_QUICK_CONTROLS_STYLE<span class="operator">=</span>universal <span class="operator">.</span><span class="operator">/</span>app

</pre>
<p>See <a href="qtquickcontrols2-environment.html">Supported Environment Variables in Qt Quick Controls 2</a> for the full list of supported environment variables.</p>
<a name="configuration-file"></a>
<h3 >Configuration file</h3>
<p>Qt Quick Controls 2 support a special configuration file, <code>:/qtquickcontrols2.conf</code>, that is built into an application's resources.</p>
<p>The configuration file can specify the preferred style (may be overridden by either of the methods described earlier) and certain style-specific attributes. The following example specifies that the preferred style is the Material style.</p>
<pre class="cpp">

  <span class="operator">[</span>Controls<span class="operator">]</span>
  Style<span class="operator">=</span>Material

</pre>
<p>See <a href="qtquickcontrols2-configuration.html">Qt Quick Controls 2 Configuration File</a> for more details about the configuration file.</p>
