Codenameone加载溢出菜单

Question

I have customized my form titlebar and added buttons to it. Is it possible to add a listener to one of the buttons to add command(s) an overflow menu and show it.

Answer 1

Yes, command/s can be added to overflow menu by using the following codes and actionPerformed is called when click on the command

Toolbar toolbar = new Toolbar();
f.setToolbar(toolbar);
toolbar.addCommandToOverflowMenu(new Command("Test") {

        @Override
        public void actionPerformed(ActionEvent evt) {
          showForm("NewForm",null);
        }

    });

Answer 2

 Please try this it displays overflow menu when you click on button.

  void showOverFlow(final Form f) {
    Toolbar toolbar = new Toolbar();
    f.setToolBar(toolbar);
    toolbar.addCommandToOverflowMenu(new Command("overflow"));
    Button button = new Button("show menu");
    button.addActionListener(new ActionListener() {

        public void actionPerformed(ActionEvent evt) {

            if (f.getToolbar() != null) {
                MenuBar mb = f.getToolbar().getMenuBar();
                if (mb != null) {
                    mb.showMenu();
                }
            }
        }
    });
    toolbar.addComponent(BorderLayout.WEST,button);

}
