<h2>Detailed Description</h2>
<p>The QStyleOptionProgressBar class is used to describe the parameters necessary for drawing a progress bar.</p>
<p>Since Qt 4.1, Qt uses the <a href="qstyleoptionprogressbarv2.html">QStyleOptionProgressBarV2</a> subclass for drawing <a href="qprogressbar.html">QProgressBar</a>.</p>
<p>An instance of the QStyleOptionProgressBar class has type <a href="qstyleoption.html#OptionType-enum">SO_ProgressBar</a> and version 1.</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 QStyleOptionProgressBar and <a href="qstyleoptionprogressbarv2.html">QStyleOptionProgressBarV2</a>.</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="qstyleoptionprogressbarv2.html">QStyleOptionProgressBarV2</a> and <a href="qstyleoption.html">QStyleOption</a>.</p>
