Right click in JavaFX for Minesweeper

Question

I want to open tiles with the left mouseclick and mark them with the right mouseclick. I read and tried a lot but somehow can't get this working.

private class Tile extends StackPane {
    private int x, y;
    private boolean hasBomb;
    private boolean isOpen = false;

    private Rectangle border = new Rectangle(TILE_SIZE - 2, TILE_SIZE - 2);
    private Text text = new Text();

    public Tile(int x, int y, boolean hasBomb) {
        this.x = x;
        this.y = y;
        this.hasBomb = hasBomb;

        border.setStroke(Color.BLACK);
        border.setFill(Color.GREY);
        text.setFont(Font.font(18));
        text.setText(hasBomb ? "X" : "");
        text.setVisible(false);

        getChildren().addAll(border, text);

        setTranslateX(x * TILE_SIZE);
        setTranslateY(y * TILE_SIZE);

        onMouseClicked: function(e:MouseEvent):Void {
            if (e.button == MouseButton.SECONDARY) {
                setOnMouseClicked(e -> open());
            }
        }
    }

Could anyonw please help?

Define "not working." What you have there looks like a syntax error. It sure isn't Java. — markspace, Jul 22 '16 at 18:14
Sorry, yes there are several syntax errors. I used this as an example: http://stackoverflow.com/questions/1515547/right-click-in-javafx — Kendel Ventonda, Jul 22 '16 at 18:16
@KendelVentonda: That's JavaFX **script**, Which is no longer supported. — fabian, Jul 22 '16 at 18:23

Something went wrong with your onMouseClicked handler.

For the correct syntax of lambda expressions, see the Syntax section of the oracle tutorial.

The correct way to do it would be

this.setOnMouseClicked(e -> {
    if (e.getButton() == MouseButton.SECONDARY) {
        open();
    }
});

Furthermore there are some declarations missing in your code snippet:

the open method
the TILE_SIZE field

The both are declared later, didn't put it in here. But your solution is easy and very logical! Thank you a lot! – Kendel Ventonda Jul 22 '16 at 18:22
