在顶部菜单中添加组件

Question

我在顶部菜单中添加了组件，有一个按钮，这是容器的主要组件。但是单击任何一个按钮或其他组件都没有效果。我怎么才能让它起作用？此外，我已经浏览了一个在顶部菜单中的南方组件的博客。我已经将cn1更新到8.1，它给出了“您的项目库是最新的”，但我仍然不能使用它（setComponentToSideMenuSouth）。我想让组件保持在侧菜单的顶部，那么setComponentToSideMenuNorth也会存在吗？

Button userArea = new Button("lead Btn");
userArea.addActionListener(e->{
    System.out.println("bbeck");
});

TextArea emailArea = new TextArea("abc");

Container userInfoContainer = BoxLayout.encloseY(userArea, emailArea);
    Container profileContainer = new Container(new BorderLayout(BorderLayout.CENTER_BEHAVIOR_CENTER));
profileContainer.add(BorderLayout.CENTER, userInfoContainer);
profileContainer.add(BorderLayout.East, new Label("abc));
profileContainer.setLeadComponent(userArea);

f.getToolbar().addComponentToSideMenu(profileContainer);

public void start() {
    if(current != null){
        current.show();
        return;
    }
    Form hi = new Form("Hi World", BoxLayout.y());
    hi.add(new Label("Hi World"));
    hi.show();

    hi.getToolbar().setComponentToSideMenuSouth(new Label("abc"));

    Command abc = new Command("abc"){

        @Override
        public void actionPerformed(ActionEvent evt) {
            System.out.println("bibek");
        }

    };
    hi.getToolbar().addCommandToSideMenu(abc);
}
