FadeTransition

public final class FadeTransition
extends Transition

This Transition creates a fade effect animation that spans its duration. This is done by updating the opacity variable of the node at regular interval.

It starts from the fromValue if provided else uses the node's opacity value.

It stops at the toValue value if provided else it will use start value plus byValue.

The toValue takes precedence if both toValue and byValue are specified.

Code Segment Example:

 
 import javafx.scene.shape.*;
 import javafx.animation.*;

 ...

     Rectangle rect = new Rectangle (100, 40, 100, 100);
     rect.setArcHeight(50);
     rect.setArcWidth(50);
     rect.setFill(Color.VIOLET);

     FadeTransition ft = new FadeTransition(Duration.millis(3000), rect);
     ft.setFromValue(1.0);
     ft.setToValue(0.3);
     ft.setCycleCount(4);
     ft.setAutoReverse(true);

     ft.play();

- Property Detail
  - node
```
public final <any> nodeProperty
```
    The target node of this Transition.
    It is not possible to change the target node of a running FadeTransition. If the value of node is changed for a running FadeTransition, the animation has to be stopped and started again to pick up the new value.

  - duration
```
public final <any> durationProperty
```
    The duration of this FadeTransition.
    It is not possible to change the duration of a running FadeTransition. If the value of duration is changed for a running FadeTransition, the animation has to be stopped and started again to pick up the new value.
    Note: While the unit of duration is a millisecond, the granularity depends on the underlying operating system and will in general be larger. For example animations on desktop systems usually run with a maximum of 60fps which gives a granularity of ~17 ms. Setting duration to value lower than Duration#ZERO will result in IllegalArgumentException.

  - interpolate
```
protected void interpolate(double frac)
```
    The method interpolate() has to be provided by implementations of Transition. While a Transition is running, this method is called in every frame. The parameter defines the current position with the animation. At the start, the fraction will be 0.0 and at the end it will be 1.0. How the parameter increases, depends on the interpolator, e.g. if the interpolator is Interpolator.LINEAR, the fraction will increase linear. This method must not be called by the user directly.
    
    Specified by:
    
    interpolate in class Transition
    
    Parameters:
    
    frac - The relative position
