其無法正常工作:如何改變矩形與我工作的這個例子中的按鈕
public class test extends Application
{
private void init(Stage primaryStage)
{
Group root = new Group();
primaryStage.setScene(new Scene(root));
String pillButtonCss = DX57DC.class.getResource("PillButton.css").toExternalForm();
// create 3 toggle buttons and a toogle group for them
ToggleButton tb1 = new ToggleButton("Left Button");
tb1.setId("pill-left");
ToggleButton tb2 = new ToggleButton("Center Button");
tb2.setId("pill-center");
ToggleButton tb3 = new ToggleButton("Right Button");
tb3.setId("pill-right");
final ToggleGroup group = new ToggleGroup();
tb1.setToggleGroup(group);
tb2.setToggleGroup(group);
tb3.setToggleGroup(group);
// select the first button to start with
group.selectToggle(tb1);

我想創造一些矩形(或對象中或對象)中,我想存儲數據。我想用按鈕切換顯示在用戶面前的矩形(對象)。我實施的例子工作不正常。你能告訴我什麼是實施這個的正確方法?
