# Class FadeTransition

java.lang.Object
javafx.animation.Animation
javafx.animation.Transition
javafx.animation.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 Details

  - ### node

    public final ObjectProperty<Node> 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.

    See Also:
      `getNode()`, `setNode(Node)`

  - ### duration

    public final ObjectProperty<Duration> 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`.

    Default value:
      400ms

      `getDuration()`, `setDuration(Duration)`

  - ### fromValue

    Default value:
      `Double.NaN`
    See Also:
      `getFromValue()`, `setFromValue(double)`

  - ### toValue

    public final DoubleProperty toValueProperty
