public abstract class Container<T extends Component>
extends BoxComponent

Class for any BoxComponent that can contain other components. Containers handle the basic behavior of containing components, namely managing, attaching, and detaching the child widgets.

When children are added to a container they are not physcially added to the DOM of the container. Subclasses are responsible for connecting the child components.

Container does not define a root element. setElement must be called by any subclass to ensure the container has an element.
