阻止父级,直到子级关闭

Question

我有一个控制器,我的按钮的动作事件打开了一个子阶段.问题是当我关闭父阶段时,子阶段也会关闭.只要子阶段打开,我想阻止父阶段关闭.

URL url = getClass().getResource("Message.fxml");
FXMLLoader fxmlLoader = new FXMLLoader();
fxmlLoader.setLocation(url);
fxmlLoader.setBuilderFactory(new JavaFXBuilderFactory());
root = (Parent)fxmlLoader.load(url.openStream());            
Stage stage = new Stage();
//stage.initStyle(StageStyle.UNDECORATED);
//stage.setFullScreen(true);
stage.setTitle("Welcome User");
stage.setScene(new Scene(root, 675, 
stage.show();

Answer 1

设置如下:

stage.initModality(Modality.WINDOW_MODAL);
stage.initOwner(primaryStage);

您可以通过将primaryStage放入主类中的静态变量来获取它:

public static Stage primaryStage;

@Override
public void start(Stage primaryStage) {
    this.primaryStage = primaryStage;
    ...
}

然后

stage.initOwner(MainApp.primaryStage);
