# Class FillTransition

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

public final class FillTransition extends Transition
This `Transition` creates an animation, that changes the filling of a shape over a `duration`. This is done by updating the `fill` variable of the `shape` at regular intervals.

It starts from the `fromValue` if provided else uses the `shape` 's `fill` value. (The `stroke` value has to be a `Color` in this case).

It stops at the `toValue` value.

Code Segment Example:

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

     ...

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

         FillTransition ft = new FillTransition(Duration.millis(3000), rect, Color.RED, Color.BLUE);
         ft.setCycleCount(4);
         ft.setAutoReverse(true);

         ft.play();

     ...

- ## Property Details

  - ### shape

    public final ObjectProperty<Shape> shapeProperty
    The target shape of this `FillTransition`.

    It is not possible to change the target `shape` of a running `FillTransition`. If the value of `shape` is changed for a running `FillTransition`, the animation has to be stopped and started again to pick up the new value.

    See Also:
      - `getShape()`
      - `setShape(Shape)`
      - `shapeProperty()`

  - ### duration

    public final ObjectProperty<Duration> durationProperty
    The duration of this `FillTransition`.

    It is not possible to change the `duration` of a running `FillTransition`. If the value of `duration` is changed for a running `FillTransition`, 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

  - ### 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
