Examples of org.eclipse.jface.resource.ColorRegistry

org.eclipse.jface.resource.ColorRegistry
A color registry maintains a mapping between symbolic color names and SWT Colors.
A color registry owns all of the Color objects registered with it, and automatically disposes of them when the SWT Display that creates the Colors is disposed. Because of this, clients do not need to (indeed, must not attempt to) dispose of Color objects themselves.

Methods are provided for registering listeners that will be kept apprised of changes to list of registed colors.

Clients may instantiate this class (it was not designed to be subclassed).
@since 3.0 @noextend This class is not intended to be subclassed by clients.
