Javafx，如何检测整个场景的onMouseMoved？

Question

我正在尝试检测鼠标是否在整个场景上移动，或者在 15 分钟不活动后不关闭应用程序。

在示例中，我有一个 Anchorpane 占据整个场景，并在其上有一个 OnMouseMoved 事件。

检测到所有移动都预计会经过 tabPane，为什么？

无论节点悬停在何处，如何设法检测场景中的所有运动？

这是文件：

MoveTest.java

public class MoveTest extends Application {

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

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

void loadIhm(Stage stage) throws URISyntaxException {
    
    URL location = MouseTestCtrl.class.getResource("/application/mouseTest.fxml");
    FXMLLoader loader = new FXMLLoader(location);

try {   
    AnchorPane root =  loader.load();    

    stage.setScene(new Scene(root));
    stage.show();

} catch (IOException e) {
    
     throw new RuntimeException("Problème FXML : mouseTest.fxml");
  }
}}

鼠标测试Ctrl

public class MouseTestCtrl {

@FXML
void moveDetected(MouseEvent event) {
    
    System.out.println("moving");

}}

Slaw 提出的解决方案效果完美

theScene.addEventFilter(MouseEvent.MOUSE_MOVED, e -> { ... }). 

尽管您可能想监听 MouseEvent.ANY 甚至 InputEvent.ANY 相反，因为用户活动通常不仅仅包含鼠标移动事件（例如，鼠标单击、鼠标拖动、按键等）。

此外，如果需要，您可以将该滤镜添加到舞台而不是场景中
