// Credit to Justin Toth.
// My own edits have been only slight: added property for image (icon) attached to menu item button

To use:

Ti.include('menu.js');
 
function createMenu() {
    menu.setTiVersion(1.4);
    menu.init({
        buttons: [
            {
                title: "Refresh",
                icon: "refresh.png",
                clickevent: function () { refresh(true); }
            },
            {
                title: "Logout",
                icon: "logout.png",
                clickevent: logout

cool! It helps me sorting out the menu for my app.

btw, do you know how to do the layout for the buttons? E.g. I'd like to have the first row of 2 buttons, then the 2nd row of 3 buttons (similar to the Yahoo Mail! app, for example)

Sorry, I've only tested this a bit, don't know about multiple rows.
