JavaFX | CycleMethod Class

CycleMethod class is a part of JavaFX. CycleMethod defines the method to use when painting outside the gradient bounds. It contains 3 Enum Constants as follows:

1. NO_CYCLE: Used to define the cycle method which uses terminal colors to fill the remaining area.
2. REFLECT: Used to define the cycle method which reflects the gradient colors, start to end then end to start.
3. REPEAT: Used to define the cycle method which repeats the gradient colors to fill the remaining area.

Commonly Used Method:

Method	Explanation
valueOf(String name)	Returns the CycleMethod of the specified name.
values()	Returns an array which contains the values of Cyclemethod type.

Below programs illustrate the use of the CycleMethod class:

1. Java program to create a LinearGradient object, add stops to it, set the CycleMethod to repeat, set proportional to false and apply it to the rectangle:
   1. In this program we will create an array of Stop objects with their offset values ranging from 0 to 1. Then create a LinearGradient object with specified stops.
   2. Set the CycleMethod to repeat and set proportional to false. then create a circle with specified x, y positions, and radius and add the linear gradient to it.
   3. After that create a VBox and set the alignment of it.
   4. Add the circle to the vbox and add the vbox to the scene and add the scene to the stage and call the show() function to display the results.

               // create stops
               Stop[] stop = {new Stop(0, Color.RED),
                            new Stop(1, Color.BLUE)};

               LinearGradient linear_gradient = new LinearGradient(0, 0,
                                35, 0, false, CycleMethod.REPEAT, stop);
   
               // create a rectangle
               Rectangle rectangle = new Rectangle(100, 100, 100, 70);
   
               // set fill
               rectangle.setFill(linear_gradient);
   
               // create VBox
               VBox vbox = new VBox(rectangle);
   
               // ste Alignment
               vbox.setAlignment(Pos.CENTER);
   
               // create a scene
               Scene scene = new Scene(vbox, 400, 300);
   
               // set the scene
               stage.setScene(scene);
   
               stage.show();
           }
   
           catch (Exception e) {

2. Java program to create a LinearGradient object, add stops to it, set the CycleMethod to reflect, set proportional to false and apply it to the circle:
   1. In this program we will create an array of Stop objects with their offset values ranging from 0 to 1.
   2. Then create a LinearGradient object with specified stops. Set the CycleMethod to reflect and set proportional to false.
   3. Create a circle with specified x, y positions, and radius and add the linear gradient to it. Create a VBox and set the alignment of it.
   4. Add the circle to the vbox and add the vbox to the scene and add the scene to the stage.
   5. Call the show() function to display the results.
