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> <hr /><h2>Type Documentation</h2><h3 class="fn"><a name="StyleOptionVersion-enum" />QStyleOptionTabV3.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> <table class="valuelist"> <tr class="odd" valign="top"> <th class="tblConst">Constant</th> <th class="tblval">Value</th> <th class="tbldscr">Description</th> </tr> <tr> <td class="topAlign"><tt>QStyleOptionTabV3.Version</tt></td> <td class="topAlign"><tt>3</tt></td> <td class="topAlign">3</td> </tr> </table> <p>The version is used by <a href="qstyleoption.html">QStyleOption</a> subclasses to implement extensions without breaking compatibility.
