java - 如何从 MenuItem On Action 方法调用 Stage.initOwner()？

Question

我刚来自Is There any Way to Create A Child Window That Has the Same Properties as the Parent?我尝试调用stage.initOwner(((Node) event.getSource()).getScene().getWindow());但它不起作用，我得到了一个异常(exception)。我认为我没有正确使用它。我应该如何尝试从 onAction 方法调用它？

原始代码块:

@FXML
private void onNewClanCreation(ActionEvent event) throws IOException {
Parent root = FXMLLoader.load(getClass().getResource("ClanCreationPanel.fxml"));
Stage stage = new Stage();
stage.setScene(new Scene(root));
stage.initOwner(((Node) event.getSource()).getScene().getWindow());
stage.setResizable(false);
stage.setTitle("New Clan Creation");
stage.show();
}

异常(exception):

`Caused by: java.lang.ClassCastException: javafx.scene.control.MenuItem cannot be cast to javafx.scene.Node at com.gmail.physicistsarah.program.core.ControlPanelController.onNewClanCreation(ControlPanelController.java:65)
... 54 more`

编辑:添加了 stage.initOwner

Answer 1

这有效:stage.initOwner(this.nameLabel.getScene().getWindow()); 谢谢@ItachiUchiha
