How to create a Line using JavaFX?
A line is a geometrical structure that joins two points on an XY plane.
In JavaFX a line is represented by the javafx.scene.shape.Line class. This class contains four properties they are −
startX − This property represents the x coordinate of the starting point of the line, you can set the value to this property using the setStartX() method.
startY − This property represents y coordinate of the starting point of the line, you can set the value to this property using the setStartY() method.
endX − This property represents the x coordinate of the endpoint of the line, you can set the value to this property using the setEndX() method.
endY − This property represents y coordinate of the endpoint of the line, you can set the value to this property using the setEndY() method.
To create a circle you need to −
Instantiate this class.
Set the required properties using the setter methods or, bypassing them as arguments to the constructor.
Add the created node (shape) to the Group object.
Example
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
import javafx.scene.shape.Line;
public class DrawingLine extends Application {
public void start(Stage stage) {
//Drawing a Line
Line line1 = new Line();
//Setting the properties of the circle
line1.setStartX(200.0);
line1.setStartY(50.0);
line1.setEndX(200.0);
line1.setEndY(250.0);
//Setting other properties
line1.setFill(Color.DARKCYAN);
line1.setStrokeWidth(8.0);
line1.setStroke(Color.DARKSLATEGREY);
Line line2 = new Line();
//Setting the properties of the circle
line2.setStartX(75.0);
line2.setStartY(150.0);
line2.setEndX(450.0);
line2.setEndY(150.0);
//Setting other properties
line2.setFill(Color.DARKCYAN);
line2.setStrokeWidth(8.0);
line2.setStroke(Color.BROWN);
//Setting the Scene
Group root = new Group(line1, line2);
Scene scene = new Scene(root, 595, 300, Color.BEIGE);
stage.setTitle("Drawing a Line");
stage.setScene(scene);
stage.show();
}
public static void main(String args[]){
launch(args);
}
}Output
