var tabGroup = Ti.UI.createTabGroup();

var win = Ti.UI.createWindow({ backgroundColor: '#fff', title: 'Win 1' }); 

win.addEventListener('open', function() { 
    alert('[open1] size: ' + win.size.width + ', ' + win.size.height); 
});
win.addEventListener('focus', function() { 
    alert('[focus1] size: ' + win.size.width + ', ' + win.size.height); 
});

tabGroup.addTab(Ti.UI.createTab({ window: win, title: win.title }));
