<div class="textblock"><p>A widget that organizes contents in tab panes. </p>
<p>This widget combines a horizontal <a class="el" href="classWt_1_1WMenu.html" title="A widget that shows a menu of options.">WMenu</a> with a <a class="el" href="classWt_1_1WStackedWidget.html" title="A container widget that stacks its widgets on top of each other.">WStackedWidget</a>, and a tab-like look.</p>
<p>A tab widget will place the tab bar on top of the contents, and fit the contents below it.</p>
