如何使用Button Click在运行时更改子fxml gui部件

Question

我正在尝试为一个复杂的gui构建一个骨架,因此我的想法是在javafx 2.1中使用mvc样式创建所有内容,因此每个组件都有一个fxml文件,如果需要css,controller和model.我试着弄清楚如何改变子场景(运行时的子fxml).有谁知道怎么做？我有点坚持这个.可以添加MainViewController吗？场景:用户点击任务栏中的按钮,包含的content1.fxml将替换为content2.fxml

这里是基本代码

MainApp.java

Loads the MainView.fxml

MainView.fxml

<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>


 <BorderPane xmlns:fx="http://javafx.com/fxml">
<center>
    <fx:include source="Content1.fxml"/>
</center>

<bottom>
    <fx:include source="TaskBar.fxml"/>
</bottom>

</BorderPane>

Content1.fxml

<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>

<StackPane xmlns:fx="http://javafx.com/fxml" fx:id="content1">
    <Label text="Hallo Java FX 2.1.1 Content1.fxml"/>
</StackPane>

Content2.fxml

<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>

<StackPane xmlns:fx="http://javafx.com/fxml" fx:id="content2">
    <Label text="Hallo Java FX 2.1.1 Content2.fxml"/>
</StackPane>

TaskBar.fxml

<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>

<HBox xmlns:fx="http://javafx.com/fxml" spacing="10" alignment="center" 
     fx:id="taskBar" fx:controller="TaskBarController">
    <children>
        <Button fx:id="taskBarButton1" onAction="#handleTaskBarButton1Action"/>     
        <Button fx:id="taskBarButton2" onAction="#handleTaskBarButton2Action"/> 
    </children>
</HBox>

TaskBarController.java

import java.net.URL;
import java.util.ResourceBundle;

import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;

public class TaskBarController implements Initializable {

// Binding with the FXML
@FXML
private Button taskBarButton1;

@FXML
private Button taskBarButton2;

@FXML
private void handleTaskBarButton1Action(ActionEvent event) {
    System.out.println("click! taskBarButton1");
}

@FXML
private void handleTaskBarButton2Action(ActionEvent event) {
    System.out.println("click! taskBarButton2");
}

@Override
public void initialize(URL location, ResourceBundle resources) {
    // TODO Auto-generated method stub

}

}

不要只包含fxml,为此创建业务逻辑层:

<BorderPane xmlns:fx="http://javafx.com/fxml">
<center>
    <Pane fx:id="content"/>
</center>

并在按钮单击处理程序中更新它:

@FXML
private void handleTaskBarButton2Action(ActionEvent event) {
   System.out.println("click! taskBarButton2");
   content.getChildren().clear();
   content.getChildren().add(FXMLLoader.load(getClass().getResource("Content2.fxml"));
}
