public class SWT
extends Object

This class provides access to a small number of SWT system-wide methods, and in addition defines the public constants provided by SWT.

By defining constants like UP and DOWN in a single class, SWT can share common names and concepts at the same time minimizing the number of classes, names and constants for the application programmer.

Note that some of the constants provided by this class represent optional, appearance related aspects of widgets which are available either only on some window systems, or for a differing set of widgets on each window system. These constants are marked as HINTs. The set of widgets which support a particular HINT may change from release to release, although we typically will not withdraw support for a HINT once it is made available.
