<h2>Detailed Description</h2>
<p>The QStyleOptionViewItemV4 class is used to describe the 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>
