JavaFx事件像Onload

Question

喜歡點擊按鈕，想爲我的屏幕負載做同樣的事情，我使用場景生成器。 這裏是我的代碼：

public class CModifierBoutique implements ControlledScreen{ 
@FXML 
ChoiceBox<String> box;   

ScreensController myController; 
    @Override 
    public void setScreenParent(ScreensController screenPage) { 
     myController = screenPage; 
    } 
@FXML 
    private void goToMain(ActionEvent event){ 
     myController.setScreen(ScreensFramework.screen1ID); 
    }  
@FXML  
    private void inialize(ActionEvent event){ 
     System.out.println(" there is the method who must be start on load this screen "); 
     System.out.println("my code is requesting the data base and the result"); 
     System.out.println("will be added to my choisebox"); 

     BoutiqueDao dao=new BoutiqueDao(); 
     List<Boutique> li=dao.DisplayAll(); 


    } 
    }

我認爲你只是爲了尋找initialize()方法。無論你的控制器可以實現Initializable接口，並做

public class CModifierBoutique implements ControlledScreen, Initializable { 

    // existing code.. 

    @Override 
    public void initialize(URL location, ResourceBundle resources) { 
     // initialization code here... 
    } 
} 

，或者你可以只包含一個無參數的方法稱爲initialize()：

public class CModifierBoutique implements ControlledScreen { 

    // existing code.. 

    public void initialize() { 
     // initialization code here... 
    } 
}
