Class DropShadow

java.lang.Object
javafx.scene.effect.Effect
javafx.scene.effect.DropShadow
public class DropShadow extends Effect
A high-level effect that renders a shadow of the given content behind the content with the specified color, radius, and offset.

Example: 



 DropShadow dropShadow = new DropShadow();
 dropShadow.setRadius(5.0);
 dropShadow.setOffsetX(3.0);
 dropShadow.setOffsetY(3.0);
 dropShadow.setColor(Color.color(0.4, 0.5, 0.5));

 Text text = new Text();
 text.setEffect(dropShadow);
 text.setCache(true);
 text.setX(10.0);
 text.setY(70.0);
 text.setFill(Color.web("0x3b596d"));
 text.setText("JavaFX drop shadow...");
 text.setFont(Font.font(null, FontWeight.BOLD, 40));

 DropShadow dropShadow2 = new DropShadow();
 dropShadow2.setOffsetX(6.0);
 dropShadow2.setOffsetY(4.0);

 Circle circle = new Circle();
 circle.setEffect(dropShadow2);
 circle.setCenterX(50.0);
 circle.setCenterY(125.0);
 circle.setRadius(30.0);
 circle.setFill(Color.STEELBLUE);
 circle.setCache(true);

  • Property Details

    • input

      public final ObjectProperty<Effect> inputProperty
      The input for this Effect. If set to null, or left unspecified, a graphical image of the Node to which the Effect is attached will be used as the input.
      Default value:
      null
      See Also:

    • radius

      public final DoubleProperty radiusProperty
      The radius of the shadow blur kernel. This attribute controls the distance that the shadow is spread to each side of the source pixels. Setting the radius is equivalent to setting both the width and height attributes to a value of (2 * radius + 1). 
             Min:   0.0
       Max: 127.0
   Default:  10.0
  Identity:   0.0
      Default value:
      10.0
      See Also:

    • width

      public final DoubleProperty widthProperty
      The horizontal size of the shadow blur kernel. This attribute controls the horizontal size of the total area over which the shadow of a single pixel is distributed by the blur algorithm. Values less than 1.0 are not distributed beyond the original pixel and so have no blurring effect on the shadow. 
             Min:   0.0
       Max: 255.0
   Default:  21.0
  Identity:  <1.0
      Default value:
      21.0
      See Also:

    • height

      public final DoubleProperty heightProperty
      The vertical size of the shadow blur kernel. This attribute controls the vertical size of the total area over which the shadow of a single pixel is distributed by the blur algorithm. Values less than 1.0 are not distributed beyond the original pixel and so have no blurring effect on the shadow. 
             Min:   0.0
       Max: 255.0
   Default:  21.0
  Identity:  <1.0
      Default value:

      THREE_PASS_BOX
      See Also:

    • spread

      public final DoubleProperty spreadProperty
      The spread of the shadow. The spread is the portion of the radius where the contribution of the source material will be 100%. The remaining portion of the radius will have a contribution controlled by the blur kernel. A spread of 0.0 will result in a distribution of the shadow determined entirely by the blur algorithm. A spread of 1.0 will result in a solid growth outward of the source material opacity to the limit of the radius with a very sharp cutoff to transparency at the radius. 
             Min: 0.0
       Max: 1.0
   Default: 0.0
  Identity: 0.0
