在场景JavaFX之间切换

Question

我在class1中创建了一个场景，然后在Class2中创建了一个scene2。如何在两者之间切换？

public class class1 extends Application{

Stage window1;
BorderPane layout1;
Scene scene1;

public static void main(String[] args) {
    launch(args);
}

@Override
public void start(Stage primaryStage) throws Exception {
    window1 = primaryStage;
    window.setTitle("Stage 1");

    // And here is a button which switchs between scenes or stages,
    //i dont know what is better.So:

button.setOnAction(e -> ?????????)



    scene1 = new Scene(layout1, 800,600);
    window1.show();
}
}

这是第二节课，我有另一个场景。

public class class2 extends Application{

Stage window2;
BorderPane layout2;
Scene scene2;

public static void main(String[] args) {
    launch(args);
}

@Override
public void start(Stage primaryStage) throws Exception {
    window2 = primaryStage;
    window2.setTitle("Stage 2");

    scene2 = new Scene(layout, 800,600);
    window2.show();
}
}

我编写这个控制器是为了跟踪不同的场景图，并轻松地切换我的舞台内容。

也许您想看看FXML:http://docs.oracle.com/javafx/2/fxml_get_started/why_use_fxml.htm#chdchibe

public class ScreenController {
    private HashMap<String, Pane> screenMap = new HashMap<>();
    private Scene main;

    public ScreenController(Scene main) {
        this.main = main;
    }

    protected void addScreen(String name, Pane pane){
         screenMap.put(name, pane);
    }

    protected void removeScreen(String name){
        screenMap.remove(name);
    }

    protected void activate(String name){
        main.setRoot( screenMap.get(name) );
    }
}

所以我可以写：

ScreenController screenController = new ScreenController(scene);
screenController.add("layout1", layout1 );
screenController.add("layout2", layout2 );
screenController.add("testSwitch", FXMLLoader.load(getClass().getResource( "TestSwitch.fxml" )));

button.setOnAction(e -> screenController.activate("layout2"));
