<h2 id="details">Detailed Description</h2>
<p>The <a href="qstyleoptiontitlebar.html">QStyleOptionTitleBar</a> class is used to describe the parameters for drawing a title bar.</p>
<p><a href="qstyleoptiontitlebar.html">QStyleOptionTitleBar</a> contains all the information that <a href="qstyle.html">QStyle</a> functions need to draw the title bar of a <a href="qmdisubwindow.html">QMdiSubWindow</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>

<p><b>See also </b><a href="qstyleoption.html">QStyleOption</a>, <a href="qstyleoptioncomplex.html">QStyleOptionComplex</a>, and <a href="qmdisubwindow.html">QMdiSubWindow</a>.</p>

<h2>Member Type Documentation</h2>
<!-- $$$StyleOptionType$$$Type -->
<h3 class="fn" id="StyleOptionType-enum"><a name="StyleOptionType-enum"></a>enum QStyleOptionTitleBar::<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>
<tr><td class="topAlign"><code>QStyleOptionTitleBar::Type</code></td><td class="topAlign tblval"><code>SO_TitleBar</code></td><td class="topAlign">The type of style option provided (<a href="qstyleoption.html#OptionType-enum">SO_TitleBar</a> for this class).</td></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="qstyleoptiontitlebar.html#StyleOptionVersion-enum">StyleOptionVersion</a>.</p>
<!-- @@@StyleOptionType -->
<!-- $$$StyleOptionVersion$$$Version -->
<h3 class="fn" id="StyleOptionVersion-enum"><a name="StyleOptionVersion-enum"></a>enum QStyleOptionTitleBar::<span class="name">StyleOptionVersion</span></h3>
<p>This enum is used to hold information about the version 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>
<tr><td class="topAlign"><code>QStyleOptionTitleBar::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>
