I want to make an animation with the "width" of my node. 

In this case my node is a "AnchorPane".

I try to make a navigation drawer in javafx.

**there is no property "width Property ()"?**

```
new Key Value (node.width Property (), 1, WEB_EASE)

```

`node.widthProperty().getValue(`) not found

My code:

```
public void changeWidth(final Node node, double width) {
    this.node = node;
    this.timeline = TimelineBuilder.create()
        .keyFrames(
            new KeyFrame(Duration.millis(20),    
                new KeyValue(    going here?   , width, WEB_EASE)
            )
        )
        .build();

    setCycleDuration(Duration.seconds(5));
    setDelay(Duration.seconds(0));
}

```

Example with "opacity" property:

```
new KeyValue(node.opacityProperty(), 1, WEB_EASE)

```

My class ConfigAnimationViewPane:

```
public class ConfigAnimationViewPane extends Transition {
    protected static final Interpolator WEB_EASE = Interpolator.EASE_BOTH;
    protected AnchorPane node;
    protected Timeline timeline;
    private boolean oldCache = false;
    private CacheHint oldCacheHint = CacheHint.DEFAULT;
    private final boolean useCache = true;

    /**
     * Called when the animation is starting
     */
    protected void starting() {
        if (useCache) {
            oldCache = node.isCache();
            oldCacheHint = node.getCacheHint();
            node.setCache(true);
            node.setCacheHint(CacheHint.SPEED);
        }
    }

    /**
     * Called when the animation is stopping
     */
    protected void stopping() {
        if (useCache) {
            node.setCache(oldCache);
            node.setCacheHint(oldCacheHint);
        }
    }

    @Override protected void interpolate(double d) {
        timeline.playFrom(Duration.seconds(d));
        timeline.stop();
    }

}

```

This is mi controller:

Move the menu to the left (the occult)

```
LeftTransition leftTransition = new LeftTransition();
                leftTransition.OpenMenu(list1);
                leftTransition.play();

```

Here I want to put my size "AnchorPane".
(Set the width of my "anchorpane") 

```
 /*ViewPaneTransition paneTransition = new ViewPaneTransition();
            paneTransition.CloseMenu(viewPane, width );
            paneTransition.play();*/

```
