<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qstyleoptionslider.html">QStyleOptionSlider</a> class is used to describe the parameters needed for drawing a slider.</p>
<p><a href="qstyleoptionslider.html">QStyleOptionSlider</a> contains all the information that <a href="qstyle.html">QStyle</a> functions need to draw <a href="qslider.html">QSlider</a> and <a href="qscrollbar.html">QScrollBar</a>.</p>
<p>For performance reasons, the access to the member variables is direct (i.e&#x2e;, using the <code>.</code> or <code>-&gt;</code> operator). This low-level feel makes the structures straightforward to use and emphasizes that these are simply parameters used by the style functions.</p>
<p>For an example demonstrating how style options can be used, see the <a href="qtwidgets-widgets-styles-example.html">Styles</a> example.</p>

<h2>Member Type Documentation</h2>
<!-- $$$StyleOptionType$$$Type -->
<h3 class="fn" id="StyleOptionType-enum"><a name="StyleOptionType-enum"></a>enum QStyleOptionSlider::<span class="name">StyleOptionType</span></h3>
<p>This enum is used to hold information about the type of the style option, and is defined for each <a href="qstyleoption.html">QStyleOption</a> subclass.</p>
<div class="table"><table class="valuelist"><tr valign="top" class="odd"><th class="tblConst">Constant</th><th class="tblval">Value</th><th class="tbldscr">Description</th></tr>

</table></div>
<p>The type is used internally by <a href="qstyleoption.html">QStyleOption</a>, its subclasses, and <a href="qstyleoption.html#qstyleoption_cast">qstyleoption_cast</a>() to determine the type of style option. In general you do not need to worry about this unless you want to create your own <a href="qstyleoption.html">QStyleOption</a> subclass and your own styles.</p>
<p><b>See also </b><a href="qstyleoptionslider.html#StyleOptionVersion-enum">StyleOptionVersion</a>.</p>

<tr><td class="topAlign"><code>QStyleOptionSlider::Version</code></td><td class="topAlign tblval"><code>1</code></td><td class="topAlign">1</td></tr>
</table></div>
<p>The version is used by <a href="qstyleoption.html">QStyleOption</a> subclasses to implement extensions without breaking compatibility. If you use <a href="qstyleoption.html#qstyleoption_cast">qstyleoption_cast</a>(), you normally do not need to check it.</p>
