<h2>Detailed Description</h2>
<p>The QStyleOptionButton class is used to describe the parameters for drawing buttons.</p>
<p>QStyleOptionButton contains all the information that <a href="qstyle.html">QStyle</a> functions need to draw graphical elements like <a href="qpushbutton.html">QPushButton</a>, <a href="qcheckbox.html">QCheckBox</a>, and <a href="qradiobutton.html">QRadioButton</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="qstyleoption.html">QStyleOption</a> and <a href="qstyleoptiontoolbutton.html">QStyleOptionToolButton</a>.</p>

<p>The ButtonFeatures type is a typedef for <a href="qflags.html">QFlags</a><ButtonFeature>. It stores an OR combination of ButtonFeature values.</p>
<p>See also <a href="qstyleoptionbutton.html#features-var">features</a>.</p>

<a name="//apple_ref/cpp/econst/QStyleOptionButton/Type"></a>
<h3 class="fn"><a name="StyleOptionType-enum"></a>enum QStyleOptionButton::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 class="valuelist" 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>QStyleOptionButton::Type</tt></td><td align="center" valign="top"><tt>SO_Button</tt></td><td valign="top">The type of style option provided (<a href="qstyleoption.html#OptionType-enum">SO_Button</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="qstyleoptionbutton.html#StyleOptionVersion-enum">StyleOptionVersion</a>.</p>
<a name="//apple_ref/cpp/tag/QStyleOptionButton/StyleOptionVersion"></a>
<a name="//apple_ref/cpp/econst/QStyleOptionButton/Version"></a>
<h3 class="fn"><a name="StyleOptionVersion-enum"></a>enum QStyleOptionButton::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 class="valuelist" 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>QStyleOptionButton::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 do not need to check it.</p>
