You have to use the Command interface. A Command will be executed then a MenuItem is activated. See JavaDoc for MenuBar/MenuItem.

hi ,

thank you for your reply but my problem it is not just a message error !!!!

i have a function with parameter like that :

public MenuBar generateMenuBar(List<Menu> menuBeanList , final Long id) {   //  function execute can't have a parameters , you see ??

MenuBar menuBarPrincipale = new MenuBar();     or  MenuItem 

 menuBarPrincipale.addClickHandler(new ClickHandler() {   // here i have a problem :( :( 

@Override

public void onClick(ClickEvent event) {

GreetingServiceAsync greetingService = GWT.create(GreetingService.class);

greetingService.loadCategoryPage(id,new AsyncCallback<GridPageModel>() {

@Override

public void onFailure(Throwable caught) {

}

@Override

public void onSuccess(GridPageModel grid) {

GridPageBuilder.build(grid);

}

});

}

});

But the command can have fields so you must create your command class witch implements the Command interface and put your parameters in the constructor to set fields

[Assiya EL]

hello,

_id in the constructor is compile but returns null after the click on the menu, I think we should pass it to paramettrs function which is calling server in this case it is execute , it is possible to add a event to menu with other solution ?


thank you

Hi Assiya,
no need to use handlers there
you can use the below code


MenuItem mntmNewItem = new MenuItem("Vivek", false, new Command() {
            public void execute() {
               
        Window.alert("Hi Vivek");
               
            }
        });
        menuBar.addItem(mntmNewItem);



Hope this code will satisfy your need
