I have a tooltip installed on my pane that is supposed to only be shown on a certain Polygon (the last one). But instead the tooltip is shown on every tile. How can I change that? Based on this code, here is a reproducible example.

package com.example.demo1;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.control.Tooltip;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.Pane;
import javafx.scene.paint.Color;
import javafx.scene.shape.Polygon;
import javafx.stage.Stage;

import java.io.IOException;

public class HelloApplication extends Application {

    private final static int WINDOW_WIDTH = 800;
    private final static int WINDOW_HEIGHT = 600;

    private final static double r = 20; // the inner radius from hexagon center to outer corner
    private final static double n = Math.sqrt(r * r * 0.75); // the inner radius from hexagon center to middle of the axis
    private final static double TILE_HEIGHT = 2 * r;
    private final static double TILE_WIDTH = 2 * n;
    @Override
    public void start(Stage stage) throws IOException {
        Pane tileMap = new Pane();
        Tooltip tooltip = new Tooltip();
        int rowCount = 4; // how many rows of tiles should be created
        int tilesPerRow = 6; // the amount of tiles that are contained in each row
        int xStartOffset = 40; // offsets the entire field to the right
        int yStartOffset = 40; // offsets the entire field downwards

        Polygon tile = null;
        for (int x = 0; x < tilesPerRow; x++) {
            for (int y = 0; y < rowCount; y++) {
                double xCoord = x * TILE_WIDTH + (y % 2) * n + xStartOffset;
                double yCoord = y * TILE_HEIGHT * 0.75 + yStartOffset;

                tile = new Tile(xCoord, yCoord);
                tileMap.getChildren().add(tile);
            }
        }
        final Polygon lastTile = tile;
        Tooltip.install(tileMap, tooltip);
        tileMap.addEventHandler(MouseEvent.MOUSE_MOVED, mouseEvent -> {
            if (lastTile.intersects(mouseEvent.getX(), mouseEvent.getY(), 1, 1)) {
                tooltip.setText("test");
            }
            else {
                tooltip.hide();
            }
        });
        BorderPane pane = new BorderPane();
        pane.setCenter(tileMap);
        Scene content = new Scene(pane, WINDOW_WIDTH, WINDOW_HEIGHT);
        stage.setScene(content);
        stage.show();
    }

    private class Tile extends Polygon {
        Tile(double x, double y) {
            // creates the polygon using the corner coordinates
            getPoints().addAll(
                    x, y,
                    x, y + r,
                    x + n, y + r * 1.5,
                    x + TILE_WIDTH, y + r,
                    x + TILE_WIDTH, y,
                    x + n, y - r * 0.5
            );

            // set up the visuals and a click listener for the tile
            setFill(Color.ANTIQUEWHITE);
            setStrokeWidth(1);
            setStroke(Color.BLACK);
            setOnMouseClicked(e -> System.out.println("Clicked: " + this));
        }
    }

    public static void main(String[] args) {
        launch();
    }
}

I would like to add more details that are not code, but I can’t think of any right now. Yet the editor is forcing me to write more text.
