Question

I was trying to do some experiments with JavaFX’ HTMLEditor component. I used the following code(excerpt):

    fxPanel=new JFXPanel();
    Platform.runLater(new Runnable() {
        @Override
        public void run() {
            Group group = new Group();
            scene = new Scene(group);               
            fxPanel.setScene(scene);
            view = VBoxBuilder.create().build();

            group.getChildren().add(view);


            edit = HTMLEditorBuilder.create().build();
           // toolPane = TabPaneBuilder.create().minHeight(60d).build();
            //toolPane.getTabs().add(new Tab("Allgemein"));

            view.getChildren().add(edit);

        }
    });

    SwingUtilities.invokeLater(new Runnable() {
        @Override
        public void run() {
            jPanel1.add(fxPanel);
        }
    });

It works fine so far with one important exception – i can’t use the return key for a BR – it seems just to be ignored. There is no reaction on this key at all. As far as i could see, any other key works as expected.

Answer 1

I noticed that CTRL–M works where Enter doesn’t. So I just worked around this by putting a KeyListener on the JFXPanel, changing the KeyChar from 10 to 13 and reposting the event to the System Event Queue. This may stop working as intended later on if the HTMLEditor starts responding to both ENTER and CTRL–M though.

fxPanel.addKeyListener(new KeyListener() {

    public void keyTyped(KeyEvent e) {
        if (e.getKeyChar() == 10) {
            e.setKeyChar((char) 13);
            Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(e);
        }
    }

    public void keyPressed(KeyEvent e) {}

    public void keyReleased(KeyEvent e) {}
});

Anyone have a better idea for now?

Edit: I found another way to get the desired effect is to install a custom KeyEventDispatcher on the current keyboard focus manager like so:

KeyboardFocusManager kfm = DefaultKeyboardFocusManager.getCurrentKeyboardFocusManager();
kfm.addKeyEventDispatcher(new KeyEventDispatcher() {
    @Override
    public boolean dispatchKeyEvent(KeyEvent e) {
        if (DefaultKeyboardFocusManager.getCurrentKeyboardFocusManager().getFocusOwner() == jfxPanel) {
            if (e.getID() == KeyEvent.KEY_TYPED && e.getKeyChar() == 10) {
                e.setKeyChar((char) 13);
            }
        }
        return false;
    }
});

This has the advantage of changing the original KeyEvent rather than posting a new one afterwards, so that if HTMLEditor were to start responding to Enter events we wouldn’t be doubling up.
