<h2>Detailed Description</h2>
<p>The QStyleOptionQ3ListView class is used to describe the parameters for drawing a <a href="q3listview.html">Q3ListView</a>.</p>
<p>This class is used for drawing the compatibility <a href="q3listview.html">Q3ListView</a>. <b>It is not recommended for new classes</b>.</p>
<p>QStyleOptionQ3ListView contains all the information that <a href="qstyle.html">QStyle</a> functions need to draw <a href="q3listview.html">Q3ListView</a>.</p>
<p>For performance reasons, the access to the member variables is direct (i.e., using the <tt>.</tt> or <tt>-></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>
<p>See also <a href="qstyleoptioncomplex.html">QStyleOptionComplex</a>, <a href="q3listview.html">Q3ListView</a>, and <a href="qstyleoptionq3listviewitem.html">QStyleOptionQ3ListViewItem</a>.</p>

<h2>Member Type Documentation</h2>
<h3 class="fn"><a name="StyleOptionType-enum"></a>enum QStyleOptionQ3ListView::StyleOptionType</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>
<p><table border="1" cellpadding="2" cellspacing="1" width="100%">
<tr><th width="25%">Constant</th><th width="15%">Value</th><th width="60%">Description</th></tr>
<tr><td valign="top"><tt>QStyleOptionQ3ListView::Type</tt></td><td align="center" valign="top"><tt>SO_Q3ListView</tt></td><td valign="top">The type of style option provided (<a href="qstyleoption.html#OptionType-enum">SO_Q3ListView</a> for this class).</td></tr>
</table></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>
<p>See also <a href="qstyleoptionq3listview.html#StyleOptionVersion-enum">StyleOptionVersion</a>.</p>
<h3 class="fn"><a name="StyleOptionVersion-enum"></a>enum QStyleOptionQ3ListView::StyleOptionVersion</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>
<p><table border="1" cellpadding="2" cellspacing="1" width="100%">
<tr><th width="25%">Constant</th><th width="15%">Value</th><th width="60%">Description</th></tr>
<tr><td valign="top"><tt>QStyleOptionQ3ListView::Version</tt></td><td align="center" valign="top"><tt>1</tt></td><td valign="top">1</td></tr>
</table></p>
<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 don't need to check it.</p>
<p>See also <a href="qstyleoptionq3listview.html#StyleOptionType-enum">StyleOptionType</a>.</p>
