Setting styleable properties & pseudo-class state to controls in JavaFX 2.2

Question

Hi All,
Greetings!
Can anyone please let me know how to create or set styleable and pseudo-class state properties for custom controls developed with JavaFX 2.2.
I found a very nice wiki regarding this. (https://wikis.oracle.com/display/OpenJDK/CSS+API+to+support+custom+UI+Controls)
But this seems to be with JavaFX 8 version. As i cannot find PseudoClass in the current version of JavaFX 2.2.
Thanks & Regards,

There is no public API in 2.2 for adding adding styleable properties and pseudo-class state to controls in JavaFX 2.2.
The implementation between 2.2 and 8.0 changed significantly in terms of API, class names, etc. The model is roughly the same, but if you implement something in 2.2 using the private implementation APIs, it will not work, and may not even compile, in 8.0.
// A pseudo-class in 2.2
    private BooleanProperty foo = new BooleanPropertyBase() {
                @Override
                protected void invalidated() {
                    impl_pseudoClassStateChanged("foo");
                @Override
                public Object getBean() {
                    return MyControl.this;
                @Override
                public String getName() {
                    return "foo";
    public boolean isFoo() {
        return foo.get();
    public void setFoo(boolean newFoo) {
        foo.set(newFoo);
    private static final long FOO_PSEUDOCLASS_STATE = StyleManager.getInstance().getPseudoclassMask("foo");
    @Override
    public long impl_getPseudoClassState() {
        long mask = super.impl_getPseudoClassState();
        if(isFoo()) mask |= FOO_PSEUDOCLASS_STATE;
        return mask;
// A styleable property in 2.2. import classes from com.sun.javafx.css
        public DoubleProperty bar = new StyleableDoubleProperty(0.0) {
                    @Override
                    public StyleableProperty getStyleableProperty() {
                        return BAR;
                    @Override
                    public Object getBean() {
                        return MyControl.this;
                    @Override
                    public String getName() {
                        return "bar";
// API used by css in 2.2
        private static final StyleableProperty<MyControl,Number> BAR =
            new StyleableProperty<MyControl,Number>("-my-bar",
                SizeConverter.getInstance(), 0.0) {
                @Override
                public boolean isSettable(MyControl ctl) {
                    return bar.isBound() == false;
                @Override
                public WritableValue<Number> getWritableValue(MyControl ctl) {
                    return ctl.bar;
         private static final List<StyleableProperty> STYLEABLES;
         static {
             final List<StyleableProperty> styleables = new ArrayList<StyleableProperty>();
             Collections.addAll(styleables,
                 BAR
             STYLEABLES = Collections.unmodifiableList(styleables);
     public static List<StyleableProperty> impl_CSS_STYLEABLES() {
         return STYLEABLES;
    public List<StyleableProperty> impl_getStyleableProperties() {
        return impl_CSS_STYLEABLES();
    }
