<hr/><a name="details" id="details"></a><h2>Detailed Description</h2>
<div class="textblock"><p>A container class which manages its contents using layout managers. </p>
<p>The Container is the Ext equivalent of <a class="el" href="classWt_1_1WContainerWidget.html" title="A widget that holds and manages child widgets.">WContainerWidget</a>, and manages other widgets. Unlike WContainerWidget, Container can only use layout managers to manage its content.</p>
<p>Typically, panels will be added directly into a layout (which may be part of an <a class="el" href="classWt_1_1Ext_1_1Container.html" title="A container class which manages its contents using layout managers.">Ext::Container</a> or a <a class="el" href="classWt_1_1WContainerWidget.html" title="A widget that holds and manages child widgets.">WContainerWidget</a>), and are components to organize your user interface. You may also add a container inside a plain <a class="el" href="classWt_1_1WContainerWidget.html" title="A widget that holds and manages child widgets.">WContainerWidget</a>, but then you should set a size for the container (using <a class="el" href="classWt_1_1WWidget.html#a5bebad8f1582b8bebf01a9ed0ee11972" title="Resizes the widget.">WWidget::resize()</a>), in pixels.</p>
<p>In most cases, using a <a class="el" href="classWt_1_1Ext_1_1Panel.html" title="A container with a title and standard GUI elements.">Panel</a> is more convenient than a <a class="el" href="classWt_1_1Ext_1_1Container.html" title="A container class which manages its contents using layout managers.">Container</a>, since a <a class="el" href="classWt_1_1Ext_1_1Panel.html" title="A container with a title and standard GUI elements.">Panel</a> also manages standard GUI components (such as menu/tool bars), and interactive controls (for resizing, for example). There is however one case where you need to use a <a class="el" href="classWt_1_1Ext_1_1Container.html" title="A container class which manages its contents using layout managers.">Container</a>, which is when you wish to use a layout manager to manage the contents of the entire view port. In that case, you should use a <a class="el" href="classWt_1_1Ext_1_1Container.html" title="A container class which manages its contents using layout managers.">Container</a> to represent the view port, by adding the <a class="el" href="classWt_1_1Ext_1_1Container.html" title="A container class which manages its contents using layout managers.">Container</a> as only child directly to the application's <a class="el" href="classWt_1_1WApplication.html#a17e118a04d962459484a12989a80bc05" title="Returns the root container.">WApplication::root()</a> container.</p>
<p>For example, the following creates a top borderlayout that spans the entire viewport: </p>
<div class="fragment"><pre class="fragment"> <a class="code" href="classWt_1_1Ext_1_1Container.html" title="A container class which manages its contents using layout managers.">Wt::Ext::Container</a> *rootContainer = <span class="keyword">new</span> <a class="code" href="classWt_1_1Ext_1_1Container.html#ab45339fc546e1e596af9585c0c375060" title="Create a new container.">Wt::Ext::Container</a>(app-><a class="code" href="classWt_1_1WApplication.html#a17e118a04d962459484a12989a80bc05" title="Returns the root container.">root</a>());
<a class="code" href="classWt_1_1WBorderLayout.html" title="A layout manager which divides the container region in five regions.">Wt::WBorderLayout</a> *topLayout = <span class="keyword">new</span> <a class="code" href="classWt_1_1WBorderLayout.html" title="A layout manager which divides the container region in five regions.">Wt::WBorderLayout</a>()
rootContainer-><a class="code" href="classWt_1_1Ext_1_1Container.html#a0707be012bd5e627e6c9d7e2b6f98afe" title="Set a layout manager for the container.">setLayout</a>(topLayout);
