如何检测 JavaFX 中的鼠标单击?

How do I detect a mouse click in JavaFX?

所以我开始尝试在我的应用程序中为不同的功能设置键,我想知道有没有办法设置 right/left 鼠标点击来执行某些操作?我无法在 KeyCode.java 中找到任何鼠标事件 而且我不确定如何应用它。

这是我的代码:

public class Exercise_31 extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {

        PendulumPane pendulumPane = new PendulumPane(500, 500);

        Scene scene = new Scene(pendulumPane);
        primaryStage.setTitle("Pendulum Animation");
        primaryStage.setScene(scene);
        pendulumPane.play();
        primaryStage.show();


        scene.setOnKeyPressed(e-> {
            switch (e.getCode()) {
                case UP: pendulumPane.increase(); break;
                case DOWN: pendulumPane.decrease(); break;
                case LEFTMOUSECLICK?  
            }
        });


    }

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

    private class PendulumPane extends Pane {

        private double w = 400;
        private double h;
        PathTransition bPath;

        Circle topC;
        Circle lowerC;
        Line line;
        Arc arc;

        PendulumPane(double width, double height) {

            w = width;
            h = height;
            setPrefWidth(w);
            setPrefHeight(h);
            arc = new Arc(w / 2, h * 0.8, w * 0.15, w * 0.15, 180, 180);
            arc.setFill(Color.TRANSPARENT);
            arc.setStroke(Color.BLACK);

            lowerC = new Circle(arc.getCenterX() - arc.getRadiusX(), arc.getCenterY(), 10);
            topC = new Circle(arc.getCenterX(), arc.getCenterY() - h / 2, lowerC.getRadius() / 2);
            arc = new Arc(topC.getCenterX(), topC.getCenterY(), w / 2, h / 2, 240, 60);
            line = new Line(
                    topC.getCenterX(), topC.getCenterY(),
                    lowerC.getCenterX(), lowerC.getCenterY());

            line.endXProperty().bind(lowerC.translateXProperty().add(lowerC.getCenterX()));
            line.endYProperty().bind(lowerC.translateYProperty().add(lowerC.getCenterY()));
            bPath = new PathTransition();
            bPath.setDuration(Duration.millis(4000));
            bPath.setPath(arc);
            bPath.setNode(lowerC);
            bPath.setOrientation(PathTransition.OrientationType.NONE);
            bPath.setCycleCount(PathTransition.INDEFINITE);
            bPath.setAutoReverse(true);

            getChildren().addAll(lowerC, topC,line);

        }

        public void play() {
            bPath.play();
        }


        public void increase() {
            bPath.setRate(bPath.getCurrentRate() + 1);
        }

        public void decrease() {
            bPath.setRate(bPath.getCurrentRate() - 1);
        }

        public void stop() {
            bPath.setRate(bPath.getCurrentRate() * 0);
        }

        public void start() {
            bPath.setRate(bPath.getCurrentRate() + 1);
        }
    }
}

我想要完成的是让右击鼠标按钮停止运动,左击再次启动它。我该怎么做?谢谢。

您的活动是 KeyEvent。如果您为鼠标定义了一个侦听器(例如 setOnMouseReleased,您会得到一个 MouseEvent,并且在该侦听器上您具有检查是否按下了通常与鼠标单击结合使用的某些键的功能:

event.isAltDown();
event.isControlDown();
event.isMetaDown();

如果您需要更多内容,则必须自己实施。 请参阅 MouseEvent.
