Question

我已经实现了一个EventHandler，它可以获得鼠标的窗口拖动：

public void mouseEventHandler(){
    final Delta dragDelta = new Delta();
    view.getScene().setOnMousePressed(new EventHandler<MouseEvent>() {
        @Override
        public void handle(MouseEvent mouseEvent) {
            dragDelta.x = mainStage.getX() - mouseEvent.getScreenX();
            dragDelta.y = mainStage.getY() - mouseEvent.getScreenY();
        }
    });
    view.getScene().setOnMouseDragged(new EventHandler<MouseEvent>() {
        @Override
        public void handle(MouseEvent mouseEvent) {
            mainStage.setX(mouseEvent.getScreenX() + dragDelta.x);
            mainStage.setY(mouseEvent.getScreenY() + dragDelta.y);
            stage.setX(mainStage.getX());
            stage.setY(mainStage.getY() + view.getScene().getHeight() + 25);
        }
    });
}

我有两个阶段：mainStage和一个舞台，它沉迷于mainStage的坐标。我的问题是，只有在我点击mainStage的窗口并拖动它时，舞台才会移动。但是如果我点击窗口的标题栏进行删除，它就不会移动。如何获得标题栏的MouseEvent？

这是show（）方法，因此您可以理解上瘾：

public void show(Stage mainStage, MenuPresenter menuPresenter){
    this.model = new Model();
    this.view = new GameView(this.model);
    this.chatWatchView = new ChatWatchView();
    this.score = this.model.getScore();
    this.menuPresenter = menuPresenter;
    this.mainStage = mainStage;
    mainStage.setScene(view.getScene());
    mainStage.centerOnScreen();
    stage = new Stage();
    stage.setScene(chatWatchView.getScene());
    stage.initStyle(StageStyle.UNDECORATED);
    stage.setX(mainStage.getX());
    stage.setY(mainStage.getY() + view.getScene().getHeight() + 25);
    stage.show();
    mainStage.show();

    startTimeline();
    activateEventHandler();
    mouseEventHandler();
    //view.setScore("Score: " + model.getScore());
}

有类似的问题。考虑将听众添加到舞台的yProperty()和void updatePosition(double stageX, double stageY) { //... }，我认为它会更好在我的情况下，我最终得到了类似的东西

stage.xProperty().addListener(((observable, oldValue, newValue) -> {
        updatePosition(newValue, stage.getY())   
}));
stage.yProperty().addListener(((observable, oldValue, newValue) -> {
        updatePosition(stage.getX(), newValue)   
}));
