parameters necessary for drawing a frame in Qt 4.4 or above.</p>
<p>QStyleOptionViewItemV4 inherits <a href="qstyleoptionviewitemv3.html">QStyleOptionViewItemV3</a>.</p>
<p>An instance of the QStyleOptionViewItemV4 class has <a href="qstyleoption.html#type-var">type</a> <a href="qstyleoption.html#OptionType-enum">SO_ViewItem</a> and <a href="qstyleoption.html#version-var">version</a> 4. 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.
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>
<p>See <a href="qstyleoptionviewitemv3.html">QStyleOptionViewItemV3</a>'s detailed
description for a discussion of how to handle "V3" classes.</p>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="StyleOptionVersion-enum" />QStyleOptionViewItemV4.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>
