public interface SwtLayoutDecorator

Common interface implemented by all SWT LayoutDecorators.

All SWT Controls require a Composite be passed into their constructor. This means the Composite must be known in advance, which prevents one from either creating a Control independent of a Composite, or moving a Control from one Composite to another. This poses a challenge for LayoutDecorators, which decide how to decorate a Control after it has been built by the WidgetBuilder.

To work around this, SWT LayoutDecorators implement an additional lifecycle hook that allows them to examine the attributes and decide on a suitable Composite before buildWidget.
