| Provides support for managing resources such as SWT |
| fonts and images. |
| <h2> |
| Package Specification</h2> |
| This package contains support for managing resources, including: |
| <ul> |
| <li> |
| font registries (<tt>FontRegistry</tt>) - for hanging on to the SWT font |
| objects needed by an application</li> |
| |
| <li> |
| color registries (<tt>ColorRegistry</tt>) - for hanging on to the SWT color |
| objects needed by an application</li> |
| |
| <li> |
| image registries (<tt>ImageRegistry</tt>) - for hanging on to the SWT image |
| objects needed by an application</li> |
| |
| <li> |
| image descriptors (<tt>ImageDescriptor</tt>) - surrogate object for creating |
| SWT images</li> |
| |
| <li> |
| string conversion (<tt>StringConverter</tt>) - for parsing property files</li> |
| </ul> |
| 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. |
| <p>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 <tt>ImageDescriptor</tt>. |
| The framework includes abstract subclasses for composing images (<tt>CompositeImageDescriptor</tt>) |
| as well as a ready-made concrete subclass for loading images from files |
| (<tt>FileImageDescriptor</tt>). |
| <p>The class <tt>JFaceResources</tt> maintains global state on behalf of |
| JFace itself consisting of JFace's own image registry, font registry, resource |
| bundle, and preference store. |
