JavaFX StrokeTransition

It animates the node’s stroke color so that the stroke color can fluctuate between the two color values over the specified duration.

In JavaFX, the class javafx.animation.FillTransition represents the Fill Transition. We need to instantiate this class in order to create an appropriate Fill Transition.

Properties

The properties of the class along with the setter methods are described in the following table.

Property	Description	Setter Methods
duration	This is an object type property of the class Duration. It represents the duration of the stroke Transition.	setDuration(Duration duration)
fromValue	This is a color type property. It represents the initial value of the color for the stroke transition.	setFromValue(Color value)
shape	This is an object type property of the class Shape. It represents the shape onto which the Stroke transition will be applied.	setShape(Shape shape)
toValue	This is color type property. It represents the target value of the color for the stroke transition.	setToValue(Color value)

Constructors

There are five constructors in the class.

public StokeTransition() : Creates the new instance of StrokeTransition with the default parameters.
public StokeTransition(Duration duration) : Creates the new instance of Stroke Transition with the specified duration value
public StokeTransition(Duration duration, Color fromValue, Color toValue) : creates the new instance of StrokeTransition with the specified duration, the initial value of the color and the target value of the color.
public StokeTransition(Duration duration, Shape shape) : creates the new instance of StrokeTransition with the specified duration and the shape onto which, the transition is to be applied.
5public StokeTransition(Duration duration, Shape shape, Color fromValue, Color toValue) : creates the new instance of StrokeTransition with the specified duration, shape, initial value of the color and target value of the color.

Example

In the following example, the stroke of the circle fluctuates from black to purple.

  package application;  import javafx.animation.StrokeTransition;  import javafx.application.Application;  import javafx.scene.Group;  import javafx.scene.Scene;  import javafx.scene.paint.Color;  import javafx.scene.shape.Circle;  import javafx.stage.Stage;  import javafx.util.Duration;  public class Stroke_Transition extends Application{  public static void main(String[] args) {  launch(args);  }  @Override  public void start(Stage primaryStage) throws Exception {  // TODO Auto-generated method stub  //Creating Circle   Circle cir = new Circle(200,150,100);  //Setting stroke and color for the circle  cir.setStroke(Color.BLUE);  cir.setFill(Color.RED);  cir.setStrokeWidth(10);    //Instantiating StrokeTransition class   StrokeTransition stroke = new StrokeTransition();    //The transition will set to be auto reserved by setting this to true  stroke.setAutoReverse(true);    //setting cycle count for the Stroke transition   stroke.setCycleCount(500);    //setting duration for the Stroke Transition   stroke.setDuration(Duration.millis(500));    //setting the Initial from value of the Stroke color  stroke.setFromValue(Color.BLACK);    //setting the target value of the Stroke color   stroke.setToValue(Color.PURPLE);    //setting polygon as the shape onto which the Stroke transition will be applied   stroke.setShape(cir);    //playing the Stroke transition   stroke.play();    //Configuring Group and Scene   Group root = new Group();  root.getChildren().addAll(cir);  Scene scene = new Scene(root,420,300,Color.WHEAT);  primaryStage.setScene(scene);  primaryStage.setTitle(“Stroke Transition example”);  primaryStage.show();    }  }
