是否可以使用JavaFx创建Java Applet？

Question

I want to create an applet using Javafx Scene Builder. I know the traditional way of creating an applet but then I recently started working with JavaFx and I am in love with the way you can create awesome User Interface designs using Scene Builder and then write neat customized code. So, far I can create desktop programs using JavaFx but now I want to write small utility programs and embed it on a browser. I honestly dislike the idea of writing codes to create the UI of an applet, so I was thinking if there was a way to create an applet using Javafx.

PS - I am new to Stackoverflow. So, please forgive any mistakes I make.

Answer 1

Applets are a dead technology, so you should forget them altogether. Support for applets has been removed at least in the newest Chrome browser, and most likely others too.

It's not possible to create applets via JavaFX either.

Answer 2

It can be done thanks to a JFXPanel which allows to embed a JavaFX component into a Swing component and from a Swing component you can easily create an Applet .

Here is an example that draws a Java FX Rectangle into an Applet :

public class Main extends Applet {

    private void initAndShowGUI() {
        // This method is invoked on Swing thread
        final JFXPanel fxPanel = new JFXPanel();
        fxPanel.setPreferredSize(new Dimension(100, 100));
        add(fxPanel);
        setVisible(true);
        Platform.runLater(
            new Runnable() {
                @Override
                public void run() {
                    initFX(fxPanel);
                }
            }
        );
    }

    private static void initFX(JFXPanel fxPanel) {
        // This method is invoked on JavaFX thread
        final Scene scene = createScene();
        fxPanel.setScene(scene);
    }

    private static Scene createScene() {
        final Rectangle rectangle = new Rectangle(100.0, 100.0);
        rectangle.setFill(Color.BLACK);
        return new Scene(new VBox(rectangle));
    }

    @Override
    public void init() {
        SwingUtilities.invokeLater(
            new Runnable() {
                @Override
                public void run() {
                    initAndShowGUI();
                }
            }
        );
    }
}

However Applets are outdated and will be removed soon so if you can avoid using them, just don't use them. Alternatively you can use the Deployment Toolkit library to embed your JavaFX application in a web page or launch it from a browser, more details about this approach here .
