JavaFX | LineTo class

LineTo class is a part of JavaFX. LineTo class draws a line from the current position to specified x and y coordinate. LineTo class inherits PathElement class.

Constructor of the class:

1. LineTo(): Creates a new LineTo object.
2. LineTo(double x, double y): Creates a new LineTo object with specified x, y coordinates.

Commonly Used Methods:

Below programs illustrate the use of LineTo Class:

1. Java program to create a path and add LineTo object to it and display it:
   • In this program, we will create a Path object named path.
   • Create an HLineTo object with specified X and Y coordinate.
   • Then create a MoveTo object named moveto.
   • Now add the MoveTo and Lineto object to the path.
   • Add this path to Group object and add the group object to the scene and add the scene to the stage and call the show() function to display the final results.

   
   

   
   
   

   // Java program to create a path and // add LineTo object to it and display it import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.*; import javafx.scene.layout.*; import javafx.stage.Stage; import javafx.scene.layout.*; import javafx.scene.paint.*; import javafx.scene.text.*; import javafx.geometry.*; import javafx.scene.layout.*; import javafx.scene.shape.*; import javafx.scene.paint.*; import javafx.scene.*;    public class LineTo_1 extends Application {        // launch the application     public void start(Stage stage)     {            try {                // set title for the stage             stage.setTitle("LineTo");                // create LineTo             LineTo Lineto = new LineTo(200, 200);                // create moveto             MoveTo moveto = new MoveTo(100, 100);                // create a Path             Path path = new Path(moveto, Lineto);                // 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:

   

2. Java program to create a path and add multiple LineTo objects to it and display it:
   • In this program, we will create a Path object named path.
   • Create four LineTo object with specified X and Y coordinates names Lineto, Lineto1, Lineto2, Lineto3.
   • Then create a MoveTo object named moveto.
   • Now add the MoveTo and Lineto objects to the path.
   • Add this path to Group object and add the group object to the scene and add the scene to the stage and call the show() function to display the final results.
