JavaFX | Shadow Class

Shadow class is a part of JavaFX. Shadow class creates a monochromatic shadow with blurry edges. The Shadow is of black Color (by default) and can be combined with the original to create a shadow. The Shadow of different color can be added with original to create a Glow effect. Shadow class inherits Effect class.

Constructors of the class:

1. Shadow(): Creates a new Shadow object.
2. Shadow(BlurType t, Color c, double r): Creates a new Shadow Object with specified blur type, color, and radius.
3. Shadow(double r, Color c): Creates a new Shadow Object with radius and color.

Commonly Used Methods:

Below programs illustrate the use of Shadow class:

1. Java program to create a Circle and add Shadow effect to it: In this program we will create a Circle named circle and create a Shadow effect shadow with specified radius and color. The shadow effect will be added to the circle using the setEffect() function and the circle will be added to the group. The circles will be translated to specific position in the stage using setTranslateX() and setTranslateY() function. The group will be added to the scene and the scene will be added to the stage.

   
   

   
   
   

   // Java program to create a Circle  // and add Shadow effect to it import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.*; import javafx.scene.layout.*; import javafx.stage.Stage; import javafx.scene.image.*; import javafx.scene.effect.*; import java.io.*; import javafx.scene.shape.Circle; import javafx.scene.paint.Color; import javafx.scene.Group;    public class shadow_1 extends Application {        // launch the application     public void start(Stage stage) throws Exception     {            // set title for the stage         stage.setTitle("shadow example");            // create a circle         Circle circle = new Circle(50.0f, 50.0f, 25.0f);            // translate to a position         circle.setTranslateX(50.0f);         circle.setTranslateY(50.0f);            // create a shadow effect         Shadow shadow = new Shadow(10, Color.RED);            // set effect         circle.setEffect(shadow);            // create a Group         Group group = new Group(circle);            // create a scene         Scene scene = new Scene(group, 200, 200);            // set the scene         stage.setScene(scene);            stage.show();     }        // Main Method     public static void main(String args[])     {            // launch the application         launch(args);     } }

   Output:

   

2. Java program to create four Circles and add Shadow effect to it( of different BlurType): In this program we will create a Circles named circle, circle1, circle2, circle3 and create a Shadow effects named shadow1, shadow2, shadow3, shadow4 with specified radius, color and blur type. The shadow effect will be added to the circle using the setEffect() function and the circles will be added to the group.The circles will be translated to specific position in the stage using setTranslateX() and setTranslateY() function. The group will be added to the scene and the scene will be added to the stage.
