They serve as a lightweight representation of images in situations where
no SWT display exists yet, and are used mainly in conjunction with image
registries. This package contains the image descriptor framework, which
is a simple hierarchy rooted at the abstract class ImageDescriptor
.
The framework includes abstract subclasses for composing images (CompositeImageDescriptor
)
as well as a ready-made concrete subclass for loading images from files
(FileImageDescriptor
).
The class JFaceResources
maintains global state on behalf of
JFace itself consisting of JFace's own image registry, font registry, resource
bundle, and preference store.
