Окно JavaFX GUI не отображается

Question

Итак, у меня есть это приложение (еще не полностью функциональное), которое я создал с помощью JavaFX в Eclipse. Проблема в том, что когда я нажимаю на игру, ничего не появляется. Нет окна графического интерфейса пользователя. Кстати, я построил его, используя Scene Builder. Когда я запускаю, ошибка не появляется. Вот мой код:

Main.Java

package application; 

import javafx.application.Application; 
import javafx.collections.FXCollections; 
import javafx.collections.ObservableList; 
import javafx.fxml.FXMLLoader; 
import javafx.stage.Stage; 
import javafx.scene.Scene; 
import javafx.scene.layout.AnchorPane; 


public class Main extends Application { 
    private Stage primaryStage; 
    @Override 
    public void start(Stage primaryStage) { 
     this.primaryStage = primaryStage; 
     mainWindow(); 
    } 

    public void mainWindow() { 
     try{ 
      FXMLLoader loader = new FXMLLoader(Main.class.getResource("MainWindowView.fxml")); 
      AnchorPane pane = loader.load(); 
      Scene scene = new Scene(pane); 

      MainWindowController controller = loader.getController(); 
      controller.setMain(this); 

      primaryStage.setScene(scene); 
      primaryStage.setResizable(false); 
      primaryStage.show(); 

     }catch(Exception e){ 
      e.printStackTrace(); 
     } 
    } 

    private ObservableList<Person> personData = FXCollections.observableArrayList(); 
    public ObservableList<Person> getPersonData() { return personData; } 

    public Main(){ 
     personData.add(new Person("Dr", "Frankenstein", "1234345", "London", "666666")); 
     personData.add(new Person("Steve", "Jobs", "112233", "Silicon Valley", "12345")); 
    } 

    public static void main(String[] args){ 

    } 
} 

MainWindowController.java

package application; 

import javafx.fxml.FXML; 
import javafx.scene.control.TableColumn; 
import javafx.scene.control.TableView; 
import javafx.scene.control.cell.PropertyValueFactory; 

public class MainWindowController { 

    @FXML TableView<Person> tableView; 
    @FXML TableColumn<Person, String> firstNameColumn; 
    @FXML TableColumn<Person, String> lastNameColumn; 

    private Main main; 

    public void initialize(){ 
     firstNameColumn.setCellValueFactory(new PropertyValueFactory<Person, String>("FirstName")); 
     lastNameColumn.setCellValueFactory(new PropertyValueFactory<Person, String>("LastName")); 
    } 

    public void setMain(Main main){ 
     this.main = main; 
     tableView.setItems(main.getPersonData()); 
    } 

    @FXML 
    public void handleNew(){ 

    } 

    @FXML 
    public void handleEdit(){ 

    } 

    @FXML 
    public void handleDelete(){ 

    } 

}

Answer 1

Ваш метод main отсутствует вызов launch():

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