64. RotateTransition

With RotateTransition we can rotate a node.

Here the button is rotated for 20 seconds, from 0 to 45 degree, and another 20 seconds, going back.

        Scene scene = new Scene(root, 500, 500, Color.PAPAYAWHIP);
        stage.setTitle("Example 64. RotateTransition");
        stage.setScene(scene);
        stage.show();
    }

    public static void main(String[] args) {
        launch();
    }
}
