a tabs in Qt 4.1 or above.</p> <p>An instance of the QStyleOptionTabV2 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> 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 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> </div> <p><b>See also </b><a href="qstyleoptiontab.html">QStyleOptionTab</a> and <a href="qstyleoption.html">QStyleOption</a>.</p> <!-- @@@QStyleOptionTabV2 --> <div class="types"> <h2>Member Type Documentation</h2> <!-- $$$StyleOptionVersion$$$Version --> <h3 class="fn"><a name="StyleOptionVersion-enum"></a>enum QStyleOptionTabV2::<span class="name">StyleOptionVersion</span></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> <table class="valuelist"><tr valign="top" class="odd"><th class="tblConst">Constant</th><th class="tblval">Value</th><th class="tbldscr">Description</th></tr> <tr><td class="topAlign"><tt>QStyleOptionTabV2::Version</tt></td><td class="topAlign"><tt>2</tt></td><td class="topAlign">2</td></tr> </table> <p>The version is used by <a href="qstyleoption.html">QStyleOption</a> subclasses to implement extensions without breaking compatibility.
