I've been trying to use the wiki code for getting keyboard input at
https://www.dukascopy.com/wiki/en/devel ... ard-events

It runs quite OK, but the key event dispatcher persists after the strategy is stopped and even after the strategy is removed from the active strategies list. The only way to get it to recognize any changes to the code is thus to close and reopen JForex. Would it be possible to fix this?

Many thanks, Bunyip

Hello,

You can initialize KeyEventDispatcher as a class variable. And then in onStop() method remove your eventDispatcher from KeyboardFocusManager. Then Key Events control will be returned to default dispatcher.

private KeyEventDispatcher eventDispatcher;

    @Override
    public void onStart(IContext context) throws JFException {
        this.engine = context.getEngine();
        this.console = context.getConsole();
        this.history = context.getHistory();
        this.context = context;
        this.indicators = context.getIndicators();
        this.userInterface = context.getUserInterface();

        eventDispatcher = event -> {
            boolean discardEvent = false;

            int closeMAsk = KeyEvent.CTRL_DOWN_MASK + 82;

            if (((event.getModifiersEx() + event.getKeyCode()) == closeMAsk)
                    && event.paramString().indexOf("KEY_PRESSED") >= 0) {
                console.getOut().println("ctrl-r pressed");
                context.executeTask(new OnKeyTask());
                discardEvent = true;
            }

            return discardEvent;
        };

        KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(eventDispatcher);
    }

    @Override
    public void onStop() throws JFException {
        KeyboardFocusManager.getCurrentKeyboardFocusManager().removeKeyEventDispatcher(eventDispatcher);
    }

Many thanks! That works just fine.
