<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>.
