Package org.eclipse.jface.resource Description
Provides support for managing resources such as SWT
fonts and images.
Package Specification
This package contains support for managing resources, including:
-
font registries (FontRegistry) - for hanging on to the SWT font
objects needed by an application
-
color registries (ColorRegistry) - for hanging on to the SWT color
objects needed by an application
-
image registries (ImageRegistry) - for hanging on to the SWT image
objects needed by an application
-
image descriptors (ImageDescriptor) - surrogate object for creating
SWT images
-
string conversion (StringConverter) - for parsing property files
The JFace resources module is an independent JFace module requiring a basic
knowledge of SWT and the JFace property change event mechanism. Familiarity
with other JFace modules is not required.
Image descriptors are objects that knows how to create an image on demand.
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.
