<h2>Detailed Description</h2>
<p>The QStyleOptionGroupBox class describes the parameters for drawing a group box.</p>
<p><a href="qstyleoptionbutton.html">QStyleOptionButton</a> contains all the information that <a href="qstyle.html">QStyle</a> functions need the various graphical elements of a group box.</p>
<p>It holds the <a href="qstyleoptiongroupbox.html#lineWidth-var">lineWidth</a> and the <a href="qstyleoptiongroupbox.html#midLineWidth-var">midLineWidth</a> for drawing the panel, the group box's <a href="qstyleoptiongroupbox.html#text-var">title</a> and the title's <a href="qstyleoptiongroupbox.html#textAlignment-var">alignment</a> and <a href="qstyleoptiongroupbox.html#textColor-var">color</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>, <a href="qstyleoptioncomplex.html">QStyleOptionComplex</a>, and <a href="qgroupbox.html">QGroupBox</a>.</p>

<h2>Member Type Documentation</h2>
<a name="//apple_ref/cpp/tag/QStyleOptionGroupBox/StyleOptionType"></a>
<a name="//apple_ref/cpp/econst/QStyleOptionGroupBox/Type"></a>
<h3 class="fn"><a name="StyleOptionType-enum"></a>enum QStyleOptionGroupBox::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>QStyleOptionGroupBox::Type</tt></td><td align="center" valign="top"><tt>SO_GroupBox</tt></td><td valign="top">The type of style option provided (<a href="qstyleoption.html#OptionType-enum">SO_GroupBox</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="qstyleoptiongroupbox.html#StyleOptionVersion-enum">StyleOptionVersion</a>.</p>
<a name="//apple_ref/cpp/tag/QStyleOptionGroupBox/StyleOptionVersion"></a>
<a name="//apple_ref/cpp/econst/QStyleOptionGroupBox/Version"></a>
<h3 class="fn"><a name="StyleOptionVersion-enum"></a>enum QStyleOptionGroupBox::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>QStyleOptionGroupBox::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>
<p>See also <a href="qstyleoptiongroupbox.html#StyleOptionType-enum">StyleOptionType</a>.</p>

<h3 class="fn"><a name="features-var"></a><a href="qstyleoptionframev2.html#FrameFeature-enum">QStyleOptionFrameV2::FrameFeatures</a> QStyleOptionGroupBox::features</h3>
<p>This variable holds the features of the group box frame.</p>
<p>The frame is flat by default.</p>
<p>See also <a href="qstyleoptionframev2.html#FrameFeature-enum">QStyleOptionFrameV2::FrameFeature</a>.</p>
<a name="//apple_ref/cpp/data/QStyleOptionGroupBox/lineWidth"></a>
<h3 class="fn"><a name="lineWidth-var"></a>int QStyleOptionGroupBox::lineWidth</h3>
<p>This variable holds the line width for drawing the panel.</p>
<p>The value of this variable is, currently, always 1.</p>
<p>See also <a href="qframe.html#lineWidth-prop">QFrame::lineWidth</a>.</p>
<a name="//apple_ref/cpp/data/QStyleOptionGroupBox/midLineWidth"></a>
<h3 class="fn"><a name="midLineWidth-var"></a>int QStyleOptionGroupBox::midLineWidth</h3>
<p>This variable holds the mid-line width for drawing the panel.</p>
<p>The mid-line width is usually used when drawing sunken or raised group box frames. The value of this variable is, currently, always 0.</p>
<p>See also <a href="qframe.html#midLineWidth-prop">QFrame::midLineWidth</a>.</p>
<a name="//apple_ref/cpp/data/QStyleOptionGroupBox/text"></a>
<h3 class="fn"><a name="text-var"></a><a href="qstring.html">QString</a> QStyleOptionGroupBox::text</h3>
<p>This variable holds the text of the group box.</p>
<p>The default value is an empty string.</p>
<p>See also <a href="qgroupbox.html#title-prop">QGroupBox::title</a>.</p>
<a name="//apple_ref/cpp/data/QStyleOptionGroupBox/textAlignment"></a>
<h3 class="fn"><a name="textAlignment-var"></a><a href="qt.html#AlignmentFlag-enum">Qt::Alignment</a> QStyleOptionGroupBox::textAlignment</h3>
<p>This variable holds the alignment of the group box title.</p>
<p>The default value is <a href="qt.html#AlignmentFlag-enum">Qt::AlignLeft</a>.</p>
<p>See also <a href="qgroupbox.html#alignment-prop">QGroupBox::alignment</a>.</p>
<a name="//apple_ref/cpp/data/QStyleOptionGroupBox/textColor"></a>
<h3 class="fn"><a name="textColor-var"></a><a href="qcolor.html">QColor</a> QStyleOptionGroupBox::textColor</h3>
<p>This variable holds the color of the group box title.</p>
<p>The default value is an invalid color with the RGB value (0, 0, 0). An invalid color is a color that is not properly set up for the underlying window system.</p>
