javafx.animation.StrokeTransition

public final class StrokeTransition
extends Transition

This Transition creates an animation, that changes the stroke color of a shape over a duration. This is done by updating the stroke variable of the shape at regular intervals.

It starts from the fromValue if provided else uses the shape 's stroke 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);
     rect.setFill(null);

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

     st.play();

 ...

Property Detail

shape

public final ObjectProperty<Shape> shapeProperty

The target shape of this StrokeTransition.

It is not possible to change the target shape of a running StrokeTransition. If the value of shape is changed for a running StrokeTransition, 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 StrokeTransition.

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

It is not possible to change fromValue of a running StrokeTransition. If the value of fromValue is changed for a running StrokeTransition, 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 StrokeTransition.

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

Default value:

null

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
