<p>An instance of the QStyleOptionTabV2 class has <a href="qstyleoption.html#type-varx">type</a> <a href="qstyleoption.html#OptionType-enum">SO_Tab</a> and <a href="qstyleoption.html#version-var">version</a> 2. 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="qstyleoptiontab.html">QStyleOptionTab</a> and QStyleOptionTabV2. One way to achieve this is to use the QStyleOptionTabV2 copy constructor. For example:</p>
<pre> if (const QStyleOptionTab *tabOption =
qstyleoption_cast<const QStyleOptionTab *>(option)) {
QStyleOptionTabV2 tabV2(*tabOption);
<span class="comment">// draw the tab using tabV2</span>
}</pre>
<p>In the example above: If <tt>tabOption</tt>'s version is 1, the extra member (<a href="qstyleoptiontabv2.html#iconSize-var">iconSize</a>) will be set to an invalid size for <tt>tabV2</tt>. If <tt>tabOption</tt>'s version is 2, the constructor will simply copy the <tt>tab</tt>'s <a href="qstyleoptiontabv2.html#iconSize-var">iconSize</a>.</p>
<p>For an example demonstrating how style options can be used, see the <a href="widgets-styles.html">Styles</a> example.</p>

<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="StyleOptionVersion-enum" />QStyleOptionTabV2.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 border="1" cellpadding="2" cellspacing="1" class="valuelist" width="100%">
<tr><th width="25%">Constant</th><th width="15%">Value</th><th width="60%">Description</th></tr>
<tr><td valign="top"><tt>QStyleOptionTabV2.Version</tt></td><td align="center" valign="top"><tt>2</tt></td><td valign="top">2</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>

<h3 class="fn"><a name="QStyleOptionTabV2-2" />QStyleOptionTabV2.__init__ (<i>self</i>, <a href="qstyleoptiontabv2.html">QStyleOptionTabV2</a>)</h3><p>Constructs a copy of the <i>other</i> style option.</p>
<h3 class="fn"><a name="QStyleOptionTabV2-3" />QStyleOptionTabV2.__init__ (<i>self</i>, <a href="qstyleoptiontab.html">QStyleOptionTab</a>)</h3><p>Constructs a <a href="qstyleoptiontabv2.html">QStyleOptionTabV2</a> copy of the <i>other</i> style option which can be either of the <a href="qstyleoptiontabv2.html">QStyleOptionTabV2</a> or <a href="qstyleoptiontab.html">QStyleOptionTab</a> types.</p>
<p>If the other style option's version is 1, the new style option's <tt>iconSize</tt> is set to an invalid value. If its version is 2, its <tt>iconSize</tt> value is simply copied to the new style option.</p>

<hr /><h2>Member Documentation</h2><h3 class="fn"><a name="iconSize-var" /><a href="qsize.html">QSize</a> iconSize</h3><p>This variable holds the size for the icons.</p>
<p>The default value is <a href="qsize.html">QSize</a>(-1, -1), i.e. an invalid size; use <a href="qstyle.html#pixelMetric">QStyle.pixelMetric</a>() to find the default icon size for tab bars.</p>
