| * For example, suppose you wanted to style the background of a JPanel |
| * named "MyPanel" differently from other JPanels. You could accomplish this |
| * by doing the following:</p> |
| * |
| * <pre><code> |
| * laf.register(Region.PANEL, "\"MyPanel\""); |
| * UIManager.put("\"MyPanel\".background", new ColorUIResource(Color.RED)); |
| * </code></pre> |
| * |
| * @param region The Synth Region that is being registered. Such as Button, or |
| * ScrollBarThumb, or NimbusFooUI.FOO_REGION. |
