JavaFX DropShadow

Constructors

There are four constructors in the class:

1. DropShadow (): It creates a new object with default parameters.
2. DropShadow (radius, colour): It creates a new object with specified colour and radius.
3. DropShadow (radius, offsetX,offsetY, colour): It creates a new object with the selected colour, radius and offset in x and y directions.
4. DropShadow (blur type, radius, colour, spread, offsetX, offsetY): It creates a new object with the selected colour, radius and offset in x and y directions, blur type and spread.

Properties

DropShadow class offers various properties to manage the state of the object, they are listed below:

Sample program

//Java code to implement drop shadow effect
//Coding Ninjas
package com.example.dropshadow_coding_ninjas;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.effect.BlurType;
import javafx.scene.effect.DropShadow;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.paint.Color;
import javafx.stage.Stage;

//Class definition
public class CodingNinjas extends Application {
   //override method
   
   //start method from application class with custom definition
   @Override
   public void start(Stage view)
   {
       Image pic = new Image("C:/Users/kvoxa/Downloads/ninja.png");
       ImageView picView1 = new ImageView(pic);
       ImageView picView2 = new ImageView(pic);
       //setting up the view coordinates
       picView1.setX(140);
       picView1.setY(90);
       picView2.setX(440);
       picView2.setY(90);

       picView1.setFitHeight(150);
       picView1.setFitWidth(350);
       picView2.setFitHeight(150);
       picView2.setFitWidth(350);
       //maintaining ratio of views
       picView1.setPreserveRatio(true);
       picView2.setPreserveRatio(true);
       
       //Creating drop shadow object and configuring its properties
       DropShadow shade = new DropShadow();
       shade.setBlurType(BlurType.GAUSSIAN);
       shade.setColor(Color.HOTPINK);
       shade.setHeight(130);
       shade.setWidth(90);
       shade.setOffsetX(20);
       shade.setOffsetY(20);
       shade.setSpread(0.3);
       shade.setRadius(20);
       picView2.setEffect(shade);
       Group root = new Group(picView1,picView2);
       
       //Configuring the scene object
       Scene scene = new Scene(root,600,300);
       view.setScene(scene);
       view.setTitle(" JavaFx Drop shadow : Coding Ninjas ");
       view.show();
   }
   
   //main method to launch
   public static void main(String[] args) {
       launch(args);
   }
}

Frequently Asked Questions

What is root?

The scene graph nodes make up the JavaFX scene tree. The topmost node is known as the root.

What is the use of the launch method?

The launch method is part of the Application class and it helps to run the JavaFX program.

How does inheritance work in the given sample program?

The class ‘CodingNinjas’ inherits from the Application class using the ‘extends’ keyword.
