SWT typed listener support.

Package Specification

This package provides the typed events and listener interfaces and, where appropriate, matching adapter classes which make up the "high level" typed listener support provided by SWT.

For contrast, see also the untyped listener support provided by class org.eclipse.swt.widgets.Event and interface org.eclipse.swt.widgets.Listener, and the addListener and removeListener methods in class org.eclipse.swt.widgets.Widget.
