// this sets the background color of the master UIView (when there are no windows/tab groups on it)
Titanium.UI.setBackgroundColor('#000');

// create tab group
var tabGroup = Titanium.UI.createTabGroup();


//
// create base UI tab and root window
//
var win1 = Titanium.UI.createWindow({  
    title:'BG Repeat',
    backgroundImage:'bg.jpg',
    backgroundRepeat:true
});
var tab1 = Titanium.UI.createTab({  
    title:'BG Repeat',
    window:win1
});

//
// create controls tab and root window
//
var win2 = Titanium.UI.createWindow({  
    title:'Image',
    backgroundColor:'#fff'
});
var tab2 = Titanium.UI.createTab({  
    title:'Image',
    window:win2
});

var image2 = Titanium.UI.createImageView({
	image:'bg.jpg'
});

win2.add(image2);



//
