<hr/><a name="details" id="details"></a><h2>Detailed Description</h2>
<div class="textblock"><p>The abstract base class for a user-interface component. </p>
<p>The user-interface is organized in a tree structure, in which each nodes is a widgets. All widgets, except for the application's root widget and dialogs, have a parent which is usually a <a class="el" href="classWt_1_1WContainerWidget.html" title="A widget that holds and manages child widgets.">WContainerWidget</a>.</p>
<p>When a widget is deleted, it is also visually removed from the user-interface and all children are deleted recursively.</p>
<p>This is an abstract base class. Implementations derive either from the abstract <a class="el" href="classWt_1_1WWebWidget.html" title="A base class for widgets with an HTML counterpart.">WWebWidget</a> (for basic widgets with a direct HTML counter-part) or from the abstract <a class="el" href="classWt_1_1WCompositeWidget.html" title="A widget that hides the implementation of composite widgets.">WCompositeWidget</a> (for anything else). To add a WWebWidget directly to a parent container, either specify the parent in the constructor (which is conventionally the last constructor argument), or add the widget to the parent using <a class="el" href="classWt_1_1WContainerWidget.html#a2cfe66d9b62940f889e99538a9f478d2" title="Adds a child widget to this container.">WContainerWidget::addWidget()</a>. Alternatively, you may add the widget to a layout manager set for a WContainerWidget.</p>
<p>A widget provides methods to manage its decorative style base on CSS. It also provides access to CSS-based layout, which you may not use when the widget is not inserted into a layout manager. </p>

<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>
