JAVA FX - 隐藏阶段丢失服务任务响应 [英] JAVA FX - Hide stage lost service task response

问题描述

在这个帖子中回答了为什么我的UI在service.start（）调用后阻塞，并且它已被解决。现在我有另一个小问题......在start（）之后我会隐藏/关闭舞台以在TrayIcon上运行应用程序。

In this post i was answer why my UI was blocking after service.start() call, and it is resolved. Now I have another "little" problem... after start() the service I will hide/close the stage to run the application on TrayIcon.

我注意到了使用hide（）/ close（）阶段，服务将被阻止，永远不会处于成功状态。我已经尝试删除此调用并且一切正常。

I've noticed that with hide()/close() the stage, the Service will be blocked and never go in SUCCEEDED status. I've tried to remove this call and all works.

我如何隐藏（）/关闭（）我的阶段而不阻止服务线程因此接收答案最小化托盘？

How I can hide()/close() my stage without block the Service thread and so receive the answer for minimize on tray?

@FXML
    private void handleRegisterButton() {

        User newUser = new User();
        newUser.setUsername(usernameTextField.getText());
        newUser.setGroup(groupChoicheBox.getSelectionModel().getSelectedItem());
        newUser.setMachineName(machineNameTextField.getText());

        this.mainApp.registerNewUser(newUser); // this is primaryStage from Main

        RegisterUserInvocation service = new RegisterUserInvocation(newUser);

        service.stateProperty().addListener(new InvalidationListener() {
            @Override
            public void invalidated(Observable observable) {
                System.out.println("Task value " + service.getState());
                if(service.getState().equals(Worker.State.SUCCEEDED)) {
                    mainApp.showMessageOnTray("Lan Alert", "Attivo!", MessageType.INFO); // Handler method to show TrayMessage
                }
            }
        });

        service.start();

        /* IF I REMOVE THIS THE APPLICATION WORKS. SURE, THE WINDOW REMAIN VISIBLE*/
        this.mainApp.getPrimaryStage().close();
    }

推荐答案

你需要调用 Platform.setImplicitExit（false） ，否则JavaFX运行时将关闭最后一个关闭阶段。

You need to invoke Platform.setImplicitExit(false), otherwise the JavaFX runtime will shut down when you close the last stage.

请参阅此示例，了解如何使用 TrayIcon 和JavaFX。

See this sample for using a TrayIcon and JavaFX.
