<h2>Detailed Description</h2>
<p>The QStyleOptionComboBox class is used to describe the parameter for drawing a combobox.</p>
<p><a href="qstyleoptionbutton.html">QStyleOptionButton</a> contains all the information that <a href="qstyle.html">QStyle</a> functions need to draw <a href="qcombobox.html">QComboBox</a>.</p>
<p>For performance reasons, the access to the member variables is direct (i.e&#x2e;, using the <tt>.</tt> or <tt>-&gt;</tt> 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="widgets-styles.html">Styles</a> example.</p>
</div>
<p><b>See also </b><a href="qstyleoption.html">QStyleOption</a>, <a href="qstyleoptioncomplex.html">QStyleOptionComplex</a>, and <a href="qcombobox.html">QComboBox</a>.</p>

<h2>Member Type Documentation</h2>
<!-- $$$StyleOptionType$$$Type -->
<h3 class="fn"><a name="StyleOptionType-enum"></a>enum QStyleOptionComboBox::<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>
<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"><tt>QStyleOptionComboBox::Type</tt></td><td class="topAlign"><tt>SO_ComboBox</tt></td><td class="topAlign">The type of style option provided (<a href="qstyleoption.html#OptionType-enum">SO_ComboBox</a> for this class).</td></tr>
</table>
<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="qstyleoptioncombobox.html#StyleOptionVersion-enum">StyleOptionVersion</a>.</p>
<!-- @@@StyleOptionType -->
<!-- $$$StyleOptionVersion$$$Version -->
<h3 class="fn"><a name="StyleOptionVersion-enum"></a>enum QStyleOptionComboBox::<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>
<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"><tt>QStyleOptionComboBox::Version</tt></td><td class="topAlign"><tt>1</tt></td><td class="topAlign">1</td></tr>
</table>
<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>
