/*! \class Container Wt/Ext/Container Wt/Ext/Container
* \brief A container class which manages its contents using layout managers.
*
* The %Container is the %Ext equivalent of WContainerWidget, and
* manages other widgets. Unlike %WContainerWidget, %Container can
* only use layout managers to manage its content.
*
* Typically, panels will be added directly into a layout (which may
* be part of an Ext::Container or a WContainerWidget), and are
* components to organize your user interface. You may also add a
* container inside a plain WContainerWidget, but then you should set
* a size for the container (using WWidget::resize()), in pixels.
*
* In most cases, using a Panel is more convenient than a Container,
* since a Panel 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
* Container, 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 Container to represent the view port, by adding the Container as
* only child directly to the application's WApplication::root()
* container.
*
* For example, the following creates a top borderlayout that spans
* the entire viewport:
* \code
* Wt::Ext::Container *rootContainer = new Wt::Ext::Container(app->root());
* Wt::WBorderLayout *topLayout = new Wt::WBorderLayout()
* rootContainer->setLayout(topLayout);
* \endcode
