/**
 * The {@code enabledProperty} {@code @Action} annotation parameter.
 * <p>
 * This example is nearly identical to {@link ActionExample1 ActionExample1}. We've added a
 * parameter to the {@code @Action} annotation for the {@code clearTitle} action:
 *
 * <pre>
 *
 * 
 * @Action(enabled = "clearEnabled")
 * public void clearTitle() {
 *     appFrame.setTitle(textField.getText());
 *     setClearEnabled(true);
 * }
 * </pre>
 *
 * The annotation parameter names a bound property from the same class. When the
 * {@code clearEnabled} property is set to false, as it is after the window's title has been
 * cleared, the {@code clearTitle} {@code Action} is disabled.
