15  * Factory used for obtaining <code>SynthStyle</code>s. Each of the
16  * Synth <code>ComponentUI</code>s will call into the current
17  * <code>SynthStyleFactory</code> to obtain a <code>SynthStyle</code>
18  * for each of the distinct regions they have.
19  * <p>
20  * The following example creates a custom <code>SynthStyleFactory</code>
21  * that returns a different style based on the <code>Region</code>:
22  * <pre>
23  * class MyStyleFactory extends SynthStyleFactory {
24  * public SynthStyle getStyle(JComponent c, Region id) {
25  * if (id == Region.BUTTON) {
26  * return buttonStyle;
27  * }
28  * else if (id == Region.TREE) {
29  * return treeStyle;
30  * }
31  * return defaultStyle;
32  * }
33  * }
34  * SynthLookAndFeel laf = new SynthLookAndFeel();
35  * UIManager.setLookAndFeel(laf);
36  * SynthLookAndFeel.setStyleFactory(new MyStyleFactory());
