Welcome guys. Learn the JavaFX UI widgets using these code snippets.

Example 1: Gfx2d

Let us look at the code

Step 1: Create Project

  1. Open your favorite Java IDE.
  2. In the menu go to File --> Create New Project.

Step 2: Dependencies

No dependencies are needed for this project.

Step 3: Write Code

Our code will comprise the following java files:

  • Gfx2DExample.java
  1. In your editor or IDE, create a file known as Gfx2DExample.java.
  2. Then add the following code:

(a). Gfx2DExample.java

We will need functionalities injected into this class via ready made classes. But first we have to import them. Let’s go ahead and do just that:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Circle;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;

Extend the class as shown below:

public class Gfx2DExample extends Application {

Our class will have the following methods:

  • void main(String[] args)
  • void start(Stage primaryStage)

We will add a main method to our Java class as shown below:

    public static void main(String[] args) {

Here is the full code:

package com.jenkov.javafx.gfx2d;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Circle;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;

public class Gfx2DExample extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    public void start(Stage primaryStage) {

        Circle circle = new Circle();
        circle.setCenterX(100);
        circle.setCenterY(100);
        circle.setRadius(125);
        circle.setStroke(Color.valueOf("#ff00ff"));
        circle.setStrokeWidth(5);
        circle.setFill(Color.TRANSPARENT);

        Rectangle rectangle = new Rectangle();
        rectangle.setX(200);
        rectangle.setY(200);
        rectangle.setWidth(300);
        rectangle.setHeight(400);
        rectangle.setStroke(Color.TRANSPARENT);
        rectangle.setFill(Color.valueOf("#00ffff"));

        Pane pane = new Pane();
        pane.getChildren().add(circle);
        pane.getChildren().add(rectangle);

        Scene scene = new Scene(pane, 1024, 800, true);
        primaryStage.setScene(scene);
        primaryStage.setTitle("2D Example");

        primaryStage.show();
    }
}
