在主fxml文件中加载fxml文件 [英] Loading fxml files inside a main fxml file

问题描述

我有一个包含多个菜单的主fxml文件。当用户单击某些按钮时，内容会发生变化，这些内容是在主屏幕上加载的单独fxml文件。整个场景不会改变，但只有一部分场景发生了变化。这是我想要制作的应用程序的简单原型！[在此处输入图像描述] [1]

I have a main fxml file with several menus. When the user clicks certain buttons, the content changes and these contents are the seperate fxml files which loads on the main screen. The entire scene doesn't change but only a part of the scene changes instead. Here is a simple prototype of the application which I want to make![enter image description here][1]

推荐答案

试试这个..

    AnchorPane pane; // pane where fxml was showing
    menu1.setOnAction(new EventHandler<ActionEvent>() {
    @Override
    public void handle(ActionEvent t) {
        openNewWindow("m1.fxml");

    }
    });
    menu2.setOnAction(new EventHandler<ActionEvent>() {
    @Override
    public void handle(ActionEvent t) {            
        openNewWindow("m2.fxml");

    }});
    menu3.setOnAction(new EventHandler<ActionEvent>() {
    @Override
    public void handle(ActionEvent t) {            
        openNewWindow("m3.fxml");

    }
    }); 

功能 openNewWindow

function openNewWindow

public void openNewWindow(String FXMLFile)
 {
     //ChildNode child;
    try {                    
        URL url = getClass().getResource(FXMLFile);
        FXMLLoader fxmlLoader = new FXMLLoader();
        fxmlLoader.setLocation(url);
        fxmlLoader.setBuilderFactory(new JavaFXBuilderFactory());
        AnchorPane page = (AnchorPane) fxmlLoader.load(url.openStream()); 

        Pane.getChildren().clear();///name of pane where you want to put the fxml
        Pane.getChildren().add(page);
    } 
    catch (IOException e) {
        e.printStackTrace();
    }
 }
