## 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 Detail

    - #### 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)`

    - #### 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
      See Also:
        `getDuration()`, `setDuration(Duration)`

    - #### fromValue

          public final ObjectProperty<Color> fromValueProperty

      Specifies the start color value for this `FillTransition`.

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

      Default value:
        `null`
      See Also:
        `getFromValue()`, `setFromValue(Color)`

    - #### toValue

          public final ObjectProperty<Color> toValueProperty

      Specifies the stop color value for this `FillTransition`.

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

      Default value:
        `null`
      See Also:
        `getToValue()`, `setToValue(Color)`

    - #### 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
