Transform the point to the Node coordinate system and use Node.contains to check, if the point is actually inside the Node:

The following example checks every 500 ms, if the screen coordinates (100, 100) are in the Button's bounds

public void start(Stage primaryStage) {
    Button btn = new Button("Get (100, 100) in here");
    Point2D pt = new Point2D(100, 100);

    Timeline timeline = new Timeline(new KeyFrame(Duration.seconds(0.5), evt ->

    StackPane root = new StackPane();

    Scene scene = new Scene(root, 200, 50);
