如何在javaFX 2.0应用程序中实现awt.CardLayout的功能? [英] How can I implement the functionality of awt.CardLayout in my javaFX 2.0 application?

问题描述

在我的javaFX 2.0应用程序中，我需要替换一个使用awt.CardLayout的组件. Cardlayout具有作为堆栈的功能，可显示堆栈中的顶部组件.而且我们也可以手动配置要显示的内容.

In my javaFX 2.0 app, I need to replace a component which is used awt.CardLayout. Cardlayout has a functionality as a stack which displays the top component in stack. And also we can manually configure which is to be displayed.

在javaFX 2.0中，有一个称为StackPane的布局.但这似乎不像Cardlayout.

In javaFX 2.0, there is a layout called StackPane. But It doesn't seems like Cardlayout.

推荐答案

没有CardLayout，但是您可以使用TabPane或简单地切换组:

There is no CardLayout, but you can use TabPane or simply switch groups:

public void start(Stage stage) {

    VBox vbox = new VBox(5);

    Button btn = new Button("1");
    Button btn2 = new Button("2");

    final Pane cardsPane = new StackPane();
    final Group card1 = new Group(new Text(25, 25, "Card 1"));
    final Group card2 = new Group(new Text(25, 25, "Card 2"));

    btn.setOnAction(new EventHandler<ActionEvent>() {
        public void handle(ActionEvent t) {
            cardsPane.getChildren().clear();
            cardsPane.getChildren().add(card1);
        }
    });

    btn2.setOnAction(new EventHandler<ActionEvent>() {
        public void handle(ActionEvent t) {
            cardsPane.getChildren().clear();
            cardsPane.getChildren().add(card2);
        }
    });

    vbox.getChildren().addAll(btn, btn2, cardsPane);
    stage.setScene(new Scene(vbox));
    stage.setWidth(200);
    stage.setHeight(200);
    stage.show();

}
