JavaFX | VLineTo Class

VLineTo class is a part of JavaFX. VLineTo class creates a vertical line path from the current position to specified Y coordinate. VLineTo class inherits PathElement class.

Constructor of the class:

1. VLineTo(): Creates an empty object of VLineTo.
2. VLineTo(double y): Creates an object of VLineTo with specified value of y coordinate.

Commonly Used Methods:

Method	Explanation
getY()	Returns the value of Y coordinate.
setY(double v)	Sets the value of Y coordinate.
toString()	Returns the string representation of VLineTo object.
yProperty()	Defines the Y coordinate.

Below programs illustrate the use of VLineTo Class:

• Java program to create a path and add VLineTo to it and display it:
  1. In this program, we will create a Path object named path.
  2. Create a VLineTo object with specified Y coordinate.
  3. Then create a MoveTo object named moveto and add the moveto and vlineto object to the path.
  4. Add this path to Group object and add the group object to the scene and add the scene to the stage.
  5. Call the show() function to display the final results.

              // set title for the stage
              stage.setTitle("VLineTo");
  
              // create VLineTo
              VLineTo vlineto = new VLineTo(200);
  
              // create moveto
              MoveTo moveto = new MoveTo(100, 100);
  
              // create a Path
              Path path = new Path(moveto, vlineto);
  
              // set fill for path
              path.setFill(Color.BLACK);
  
              // set stroke width
              path.setStrokeWidth(2);
  
              // create a Group
              Group group = new Group(path);
  
              // create a scene
              Scene scene = new Scene(group, 400, 300);
  
              // set the scene
              stage.setScene(scene);
  
              stage.show();
          }
  
          catch (Exception e) {
  
              System.out.println(e.getMessage());
          }
      }
  
      // Main Method
      public static void main(String args[])
      {
  
          // launch the application
          launch(args);
      }
  }

  Output:

  

• Java program to create a path and add multiple VLineTo object to it and display it:
  1. In this program, we will create a Path object named path.
  2. Create three VLineTo objects with specified Y coordinate.
  3. Then Create three MoveTo object named moveto, moveto_1, and moveto_2.
  4. Add all the moveto and vlineto objects to the path in a order.
  5. Add this path to Group object and add the group object to the scene and add the scene to the stage.
  6. Call the show() function to display the final results.
