问题描述

我开发一个小程序。我想使用JavaFx的创建控件。目前，我使用的是JFXPanel。这里是code：

I'm developing an applet. I want to use JavaFx to create the controls. Currently, I'm using An JFXPanel. Here is the code:

private JFXPanel jfxPanel;
private Canvas canvas;
private Scene scene;
private BorderPane borderPane;

public void init() {
    jfxPanel = new JFXPanel();

    Platform.runLater(new Runnable() {
        @Override
        public void run() {
            jfxPanel.setScene(createScene());
            add(jfxPanel);
        }
    });
}

public Scene createScene() {
    borderPane = new BorderPane();
    scene = new Scene(borderPane, 400, 800);
    canvas = new Canvas();

    canvas.getGraphicsContext2D().setFill(Color.RED);

    borderPane.setCenter(canvas);

    return scene;
}

public void paint(Graphics g) {
}

的问题是，它不工作。我什么都看不到。你有什么想法？
