<h2 id="details">Detailed Description</h2>
<p>The <a href="qstyleoptionheader.html">QStyleOptionHeader</a> class is used to describe the parameters for drawing a header.</p>
<p><a href="qstyleoptionheader.html">QStyleOptionHeader</a> contains all the information that <a href="qstyle.html">QStyle</a> functions need to draw the item views' header pane, header sort arrow, and header label.</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>

<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>
