应用程序启动时运行JFXDialog

Question

目前，我正在建立一个客户端服务器聊天GUI来发送和接收消息。我想要的是当应用程序启动时，JFXDialog打开并询问用户名，名字，姓氏和服务器IP地址。 我设法在initialize方法的控制器类中创建一个。我为JFXDialog做了一个fxml，我想用它代替（缩短控制器类中的代码）。有没有办法做到这一点？

JFXDialog来自 JFoenix

所有代码都位于Github Gist

ClientChatController.java是控制器类。

clientGUI.fxml是包含要显示的所有元素的主GUI文件。

dialog.fxml是需要使用的文件，而不是控制器类中的硬编码值。

目前ClientChatController.java中的硬编码代码正在运行。我想用dialog.fxml文件替换它。应用程序启动时应显示该对话框。

据我所知，JFXDialog需要成为StackPane的孩子。

注意：不在StackOverFlow上发布代码的原因是因为在Github Gist上更容易看到它。

控制器类

public class ClientChatController implements Initializable
{
    private ArrayList<Label> users = new ArrayList<Label>();
    @FXML
    private JFXListView<Label> userList;
    @FXML
    private JFXListView<Label> conversationList;
    @FXML
    private StackPane stackPane;
    @FXML
    private JFXTextField username;
    @FXML
    private JFXTextField firstname;
    @FXML
    private JFXTextField lastname;
    @FXML
    private JFXTextField serverIP;

    @Override
    public void initialize(URL location, ResourceBundle resources)
    {

        //open dialog that contains text field for username, firstname,
        //lastname and server IP address

        JFXDialogLayout content = new JFXDialogLayout();
        content.setHeading(new Text("Setup"));
        VBox vbox = new VBox(10);
        vbox.getChildren()
            .addAll(username, firstname, lastname, serverIP);
        content.setBody(vbox);
        JFXDialog dialog = new JFXDialog(stackPane, content, JFXDialog.DialogTransition.CENTER);
        JFXButton button = new JFXButton("Connect");
        button.setOnAction(new EventHandler<ActionEvent>()
        {
            @Override
            public void handle(ActionEvent event)
            {
                System.out.println("Username: " + username.getText());
                System.out.println("Firstname: " + firstname.getText());
                System.out.println("Lastname: " + lastname.getText());
                System.out.println("ServerIP: " + serverIP.getText());
                dialog.close();
            }
        });

        content.setActions(button);
        dialog.show();
    }

    @FXML
    public void clientSetup(ActionEvent event)
    {
        //NOT BEING USED AT THE MOMENT
        System.out.println("Username: " + username);
        System.out.println("Firstname: " + firstname);
        System.out.println("Lastname: " + lastname);
        System.out.println("ServerIP: " + serverIP);
    }
}

用于显示内容的fxml

<?xml version="1.0" encoding="UTF-8"?>

                           </padding>
                           <center>
                               <JFXTextArea fx:id="textArea"
                                            maxHeight="92"

                               <JFXButton fx:id="sendBtn"
                                          alignment="CENTER"

对话框我将使用的文件而不是ClientChatController.java中的硬编码代码
