在borderpane中心进行场景切换，形成javafx中的另一个类

时间：2018-03-22 11:29:13

标签： java javafx fxml

我正在创建窗口应用程序，其中base作为边框窗格。我在类中定义了这个边框窗格。在边框窗格的中心，我已经放置了锚窗格。此锚点窗格在另一个类控制器中定义。在锚点窗格中，当我单击按钮时，我想将边框窗格的中心更改为另一个场景。我怎么能让它成为可能？

dashboard.fxml it contains the border pane in center odf the border pane i have loaded the homepage.fxml when I press the item button on the dashboard I want to change the center alone like this i.e itempage.fxml

您可以随时随地创建边框窗格作为fxml文件加载

答案 1 :(得分：0)

创建一个公共类，该类将接受您需要公开传递的数据

ChangeScenes.java 

//changes the display in borderpane center

public static void moveToCenter(URL ui, BorderPane borderpane){
try {
        Parent root = FXMLLoader.load(ui);
        borderpane.setCenter(root);
    } catch (IOException ex) {
        Logger.getLogger(ChangeScenes.class.getName()).log(Level.SEVERE, null, ex);
    }
}

然后您可以在任意位置调用它

MainController.java 

@FXML private BorderPane borderPane;

@FXML
private void handlePersonalInfo(ActionEvent event) {
        ChangeScenes.moveToCenter(getClass().getResource("/AnotherScene.fxml"), borderPane);
    }
