使用afterburner.fx处理多个视图

Question

我在一个项目中工作，我使用的dashboard.fxml包含一个拆分窗格。splitPane包含两个锚定窗格。左侧我没有几个选项卡，右侧我生成了view（这是其他一些FXML文件在afterburner.fx中使用视图）。 This is my dashboard.fxml, i generate the new view at the right side as shown in image.

这是我的DashboardPresenter.java文件

public class DashboardPresenter implements Initializable {

private ResourceBundle resources = null;

@FXML
private AnchorPane paneRegister;
@FXML
private AnchorPane paneRenewalMain;
@FXML
private AnchorPane paneAddOns;
@FXML
private AnchorPane paneReports;
@FXML
private AnchorPane paneEnquiryTab;
@Inject
private AddonPresenter addonPresenter;

//require views -----------------------------------------------------------------

EnquiryView enquiryView;
RegisterView registerView;
RenewalView renewalView;
ReportsView reportView;
public AddonView addOnView;

public DashboardPresenter(){
    enquiryView = new EnquiryView();
    if(paneEnquiryTab != null){
        paneEnquiryTab.getChildren().add(enquiryView.getView());
        paneEnquiryTab.setDisable(false);
        paneEnquiryTab.setOpacity(1);
    }
    registerView = new RegisterView();
    if(paneRegister != null){
        paneRegister.getChildren().add(registerView.getView());
        paneRegister.setDisable(false);
        paneRegister.setOpacity(1);
    }
    renewalView = new RenewalView();
    addOnView = new AddonView();
}


@Override
public void initialize(URL location, ResourceBundle resources) {
    this.resources = resources;
}

public void clearAnchorPane(){
    if(paneRegister != null){
       paneRegister.getChildren().clear();   
    }
    if(paneRenewalMain != null){
       paneRenewalMain.getChildren().clear();
    }
    if(paneRenewalMain != null){
        paneRenewalMain.getChildren().clear();
    }
    if(paneAddOns != null){
        paneAddOns.getChildren().clear();
    }
    if(paneReports != null){
        paneReports.getChildren().clear();
    }
    if(paneEnquiryTab != null){
        paneEnquiryTab.getChildren().clear();
    }
}

@FXML
private void onEnquiryTab(Event event) {
    clearAnchorPane();
    if(paneEnquiryTab != null){

        paneEnquiryTab.getChildren().add(enquiryView.getView());
        paneEnquiryTab.setDisable(false);
        paneEnquiryTab.setOpacity(1);
    }
}

@FXML
private void onRegistrationTab(Event event) {
    clearAnchorPane();     
    paneRegister.getChildren().add(registerView.getView());
    paneRegister.setDisable(false);
    paneRegister.setOpacity(1);

}

@FXML
private void onRenewalTab(Event event) {
    clearAnchorPane();        
    paneRenewalMain.getChildren().add(renewalView.getView());
    paneRenewalMain.setDisable(false);
    paneRenewalMain.setOpacity(1);
}

@FXML
private void onAddOnTab(Event event) {
    clearAnchorPane();
    paneAddOns.getChildren().add(addOnView.getView());
    paneAddOns.setDisable(false);
    paneAddOns.setOpacity(1);
}

@FXML
private void onReportTab(Event event) {
    clearAnchorPane();
}

}

我想在左侧的定位面板上打开一个新的fxml文件。我可以轻松地做到这一点。如上面的代码所示（在onAddOnTab事件中）。 the view looks like this after inserting new view.

这是我的AddonPresenter.java。此文件是我的新视图Controller

public class AddonPresenter implements Initializable {
private ResourceBundle resources = null;
@FXML
private AnchorPane paneAddOnStartUp;

    FreezeView freeze;
    public AddonPresenter(){
        freeze = new FreezeView();
    }
public void clearAnchorPane(){
    System.out.println("**************clearAnchorPane() AddonPresenter 
    initiated****************");
    dashboard.clearAnchorPane();
    if(paneAddOnStartUp != null){
        paneAddOnStartUp.getChildren().clear();
    }
}
@Override
public void initialize(URL location, ResourceBundle resources) {
    this.resources = resources;
}
@FXML
private void onFreezeClicked(MouseEvent event) {
    System.out.println("**********************OnFreeze 
                       Entered********************");
    clearAnchorPane();
    paneAddOnStartUp.getChildren().add(freeze.getView());
    paneAddOnStartUp.setDisable(false);
    paneAddOnStartUp.setOpacity(1);
}
}

现在，当我通过AddOn.fxml添加新视图时。我创建视图的多个实例。因此，当我从创建的第三个视图中按“后退”按钮时。this image shows the problem encountered.

FreezePresenter.java文件。该文件包含导致问题的后退按钮逻辑。

public class FreezePresenter implements Initializable {

private ResourceBundle resources = null;
@FXML
private AnchorPane paneFreezeMember;
@Inject
private AddonPresenter addonpresenter;


@Override
public void initialize(URL location, ResourceBundle resources) {
    this.resources = resources;
}
@FXML
private void onBackButton(ActionEvent event) {
    new AddonPresenter().clearAnchorPane();
    AddonView addonView = new AddonView();
    addonpresenter.clearAnchorPane();
    paneFreezeMember.getChildren().add(addonView.getView());
    paneFreezeMember.setDisable(false);
    paneFreezeMember.setOpacity(1);
}    
}

感谢您的帮助。
