Besides applying simple colors to visual objects, JavaFX provides built-in classes to apply gradient effect to objects. Gradients are created using a gradient class such as javafx.scene.paint.LinearGradient and the javafx.scene.paint.Stop class to define a graded color that makes up the gradient. The following creates a graded Rectangle: def w = 400;def h = 200;def linearGrad = LinearGradient { startX: 0.0, startY: 0.0, endX: 0.0, endY: 1.0 proportional: true stops: [ Stop {offset: 0.0 color: Color.RED}, Stop {offset: 1.0 color: Color.BLACK}, ]}def rec0 = Rectangle { width: 100 height: 90 x: 30 y: h - 90 fill: linearGrad stroke:Color.SILVER}The code above produces the figure shown below. Notice the two colors, Color.BLACK and Color.RED, declared in the two instances of Stop.  | The materials on this website represent a small sample of content loosely based on the book JavaFX Application Development Cookbook.
