Browser

public class Browser extends Composite (Code)

Instances of this class implement the browser user interface metaphor. It allows the user to visualize and navigate through HTML documents.

Note that although this class is a subclass of Composite, it does not make sense to set a layout on it.

IMPORTANT: This class is not intended to be subclassed.
