35   * This UIDefaults implementation is functionally read-only - changing values with put()
36   * has no real effect. It is useful for code that needs to read UIDefaults to create derivative
37   * UIResources and acts as a stub for code that attempts to change default resources.
38   *
39   * If possible with SWT, put() could be modified to recognize set keys and call appropriate methods to
40   * update the SWT defaults. However, since SWT uses native controls this is probably difficult.
