<div class="descr">
<h2>Detailed Description</h2>
<p>The QStyleOptionTabV3 class is used to describe the parameters necessary for drawing a tabs in Qt 4.5 or above.</p>
<p>An instance of the QStyleOptionTabV3 class has <a href="qstyleoption.html#type-var">type</a> <a href="qstyleoption.html#OptionType-enum">SO_Tab</a> and <a href="qstyleoption.html#version-var">version</a> 3. 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>, <a href="qstyleoptiontabv2.html">QStyleOptionTabV2</a> and QStyleOptionTabV3. One way to achieve this is to use the QStyleOptionTabV3 copy constructor. For example:</p>
<pre class="cpp"> <span class="keyword">if</span> (<span class="keyword">const</span> <span class="type"><a href="qstyleoptiontab.html">QStyleOptionTab</a></span> <span class="operator">*</span>tabOption <span class="operator">=</span>
qstyleoption_cast<span class="operator"><</span><span class="keyword">const</span> <span class="type"><a href="qstyleoptiontab.html">QStyleOptionTab</a></span> <span class="operator">*</span><span class="operator">></span>(option)) {
QStyleOptionTabV2 tabV2(<span class="operator">*</span>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>
