JavaFX Java17-退出全屏事件

Question

我已经在应用程序中添加了一个自定义工具栏（放置窗口操作的位置）。到目前为止，一切进展顺利。与窗口处理相关，我正在寻找处理“全屏关闭”事件的可能性。场景：应用程序以窗口模式启动-

main.java

MainController mc = new MainController();
Parent root = FXMLLoader.load(getClass().getResource("welcome-view.fxml"));
stage.initStyle(StageStyle.TRANSPARENT);
mc.doSwitchScenes(stage, root);
stage.show();

主控制器。JAVA

...
private String title = "Project Apollo";
private Color fillColor = TRANSPARENT;
private int minWidth = 800;
private int minHeight = 600;
...

public void btnMinimize(MouseEvent mouseEvent) {
    Stage stage = (Stage)((Circle)mouseEvent.getSource()).getScene().getWindow();
    // is stage minimizable into task bar. (true | false)
    stage.setIconified(true);
};

public void btnCloseApp(MouseEvent mouseEvent) {
    Platform.exit();
    System.exit(0);
}

public void btnFullscreen(MouseEvent mouseEvent) {
    Stage stage = (Stage)((Circle)mouseEvent.getSource()).getScene().getWindow();
    stage.setFullScreen(true);
    Scene actualScene = ((Node)mouseEvent.getSource()).getScene();
    Parent hbc = (Parent) actualScene.lookup("#headerBarContainer");

    if(hbc != null){
        hbc.setVisible(false);
    }
    System.out.println("clicked FS");

}
...

关键是，至少在MacOS上，窗口有其本机操作系统控件可以退出全屏-是否有可能将此事件作为目标，或者至少阶段大小的变化可能？

听stage。fullScreenProperty（）并响应更改：

stage.fullScreenProperty().addListener((ChangeListener) (obs,oldValue,newValue) -> 
                                          {/*TODO respond to changes in full screen */;});
