<div class="textblock"><p>A progress bar. </p>
<p>The progress bar can be used to indicate the progress of a certain operation. The text displayed in the progress bar can be customized by specializing <a class="el" href="classWt_1_1WProgressBar.html#add10d474c0ebfca950260ae2fcea876a" title="Returns the text displayed inside the progress bar.">text()</a>.</p>
<p>To use the progress bar, you need to give it a range (minimum and maximum value), and update the progress using <a class="el" href="classWt_1_1WProgressBar.html#ac0cf5ad1588716d0ef9501fddc421b8c" title="Sets the current progress.">setValue()</a>.</p>
<p>WProgressBar is an <a class="el" href="classWt_1_1WWidget.html#ac78e3af143883334c82031790c87416e">inline </a> widget.</p>
<h3>CSS</h3>
<p>Using HTML4, the widget is implemented using a set of nested DIVs. The element can be styled using the <code>Wt-progressbar</code> style. It may be styled through the current theme, or you can override the style using internal or external CSS as appropriate.</p>
<dl class="note"><dt><b>Note:</b></dt><dd>With the advent of HTML5, this widget will be implemented using the native HTML5 control when available. </dd></dl>

<p>Resizes the widget. </p>
<p>Specifies a fixed size for this widget, setting CSS <code>width</code> and <code>height</code> properties. By default a widget has automatic width and height, which sets a size for the widget following CSS rules.</p>
<p>When the widget is not managed by a layout manager, the automatic (natural) size of a widget depends on whether they widget is a <em>block</em> or <em>inline</em> widget:</p>
<ul>
<li>a <em>block</em> widget takes by default the width of the parent, and the height that it needs based on its contents</li>
<li>an <em>inline</em> widget takes the width and height that it needs based on its contents (possibly wrapping over multiple lines). The width and height of an inline widget cannot be changed (by the letter of CSS, although most browsers will react to it in varying ways).</li>
</ul>
<p>When inserted in a layout manager, the size set will be used as a widget's preferred size, but the widget may be given a different size by the layout manager based on available space and stretch factors. The actual size given by a layout manager may be retrieved by making the widget "layout size aware", using <a class="el" href="classWt_1_1WWidget.html#a4f83592912a7f8fa4fd35dadde78ee74" title="Sets the widget to be aware of its size set by a layout manager.">setLayoutSizeAware()</a>. If you have defined a <code>"wtResize()"</code> JavaScript method for the widget, then this method will also be called.</p>
<p>The default width and height of a widget is <a class="el" href="classWt_1_1WLength.html#a0cf39ca4225776879d56ade60320c31a" title="An 'auto' length.">WLength::Auto</a>.</p>
