<h2>Detailed Description</h2>
<p>The QStyleOptionProgressBarV2 class is used to describe the parameters necessary for drawing a progress bar in Qt 4.1 or above.</p>
<p>An instance of this class has <a href="qstyleoption.html#type-varx">type</a> <a href="qstyleoption.html#OptionType-enum">SO_ProgressBar</a> and <a href="qstyleoption.html#version-var">version</a> 2.</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. 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>If you create your own <a href="qstyle.html">QStyle</a> subclass, you should handle both <a href="qstyleoptionprogressbar.html">QStyleOptionProgressBar</a> and QStyleOptionProgressBarV2. One way to achieve this is to use the QStyleOptionProgressBarV2 copy constructor. For example:</p>
<pre> if (const QStyleOptionProgressBar *progressBarOption =
qstyleoption_cast<const QStyleOptionProgressBar *>(option)) {
QStyleOptionProgressBarV2 progressBarV2(*progressBarOption);
<span class="comment">// draw the progress bar using progressBarV2</span>
}</pre>
<p>In the example above: If the <tt>progressBarOption</tt>'s version is 1, the extra members (<a href="qstyleoptionprogressbarv2.html#orientation-var">orientation</a>, <a href="qstyleoptionprogressbarv2.html#invertedAppearance-var">invertedAppearance</a>, and <a href="qstyleoptionprogressbarv2.html#bottomToTop-var">bottomToTop</a>) are set to default values for <tt>progressBarV2</tt>. If the <tt>progressBarOption</tt>'s version is 2, the constructor will simply copy the extra members to progressBarV2.</p>
<p>For an example demonstrating how style options can be used, see the <a href="widgets-styles.html">Styles</a> example.</p>
