JavaFX | InnerShadow Class

InnerShadow class is a part of JavaFX. InnerShadow class creates a high-level effect that renders a shadow inside the edges of the object with given specified radius, offset, choke, color and blur type. InnerShadow class inherits the Effect class.

Constructors of the class:

  1. InnerShadow(): Creates a new Object of InnerShadow.
  2. InnerShadow(BlurType blurType, Color color, double radius, double choke, double offsetX, double offsetY): Creates a new Object of InnerShadow with specified blurType, color, radius, choke, and offset.
  3. InnerShadow(double r, Color c): Creates a new Object of InnerShadow with specified radius and color.
  4. InnerShadow(double radius, double offsetX, double offsetY, Color color): Creates a new Object of InnerShadow with specified radius, offset and color.

Commonly Used Methods:



Method Explanation
getBlurType() Returns the blur type of the Effect.
setBlurType(BlurType v) Sets the blur type of the Effect.
getChoke() Returns the value of the property choke.
setChoke(double d) Sets the value of the property choke.
setColor(Color v) Sets the color of the effect.
getColor() Returns the color of the effect.
setInput(Effect v) Sets the value of property input.
getInput() Returns the value of property input.
setOffsetX(double v) Sets the value of offsetX of the effect.
setOffsetY(double v) Sets the value of offsetY of the effect.
getOffsetX() Sets the value of offsetX of the effect
getOffsetY() Sets the value of offsetY of the effect.
setRadius(double v) Sets the value of radius of the effect.
getRadius() Sets the value of radius of the effect.

Below programs illustrate the use of InnerShadow class:

  1. Java program to create a Circle and add InnerShadow effect to it: In this program we will create a Circle named circle and create a InnerShadow effect Inner_shadow with specified radius and color. The InnerShadow 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.

            // set fill for circle
            circle.setFill(Color.BLUE);
      
            // translate to a position
            circle.setTranslateX(50.0f);
            circle.setTranslateY(50.0f);
      
            // create a sepia_tone effect
            InnerShadow sepia_tone = new InnerShadow(10, Color.RED);
      
            // set effect
            circle.setEffect(sepia_tone);
      
            // 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 InnerShadow effect to it which are of different blur types and diiferent values of choke, offsetX, offsetY and radius: In this program we will create the Circles named circle, circle1, circle2, circle3 and the InnerShadow effects named Inner_shadow1, Inner_shadow2, Inner_shadow3, Inner_shadow4 with specified radius, color, offsetX, offsetY, choke and blur type. The InnerShadow 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.
