Returns the widget that visually represents the indicator.
<p>
You should reimplement this method to return a widget that will be shown to indicate that a response is pending. The widget should be positioned using CSS.<p>
The widget will be shown and hidden using <a class="el" href="classWt_1_1WWidget.html#52dcef5a385ddfa0a8c3e6c20000f181" title="Shows the widget.">WWidget::show()</a> and <a class="el" href="classWt_1_1WWidget.html#0825c3ccbd4999afc1a88fafa6aa6fc7" title="Hides the widget.">WWidget::hide()</a>. If you want to customize this behaviour, you should reimplement the <a class="el" href="classWt_1_1WWidget.html#11bd299d9afd0d83f17ac454c85c43a2" title="Sets whether the widget is hidden.">WWidget::setHidden()</a> method. Note that <a class="el" href="classWt_1_1WWidget.html#52dcef5a385ddfa0a8c3e6c20000f181" title="Shows the widget.">show()</a> and <a class="el" href="classWt_1_1WWidget.html#0825c3ccbd4999afc1a88fafa6aa6fc7" title="Hides the widget.">hide()</a> are stateless slots, and thus you need to make sure that your implementation comforms to that contract, so that it may be optimized to JavaScript (the server-side implementation will only be called during stateless slot prelearning).<p>
<dl class="note" compact><dt><b>Note:</b></dt><dd>The widget will not be added to the <a class="el" href="classWt_1_1WApplication.html#17e118a04d962459484a12989a80bc05" title="Returns the root container.">WApplication::root()</a> container. </dd></dl>
