Titanium.UI.TabGroup.animate

Note that if you use animate to move a view, the view's actual position is changed, but its layout properties, such as top, left, center and so on are not changed--these reflect the original values set by the user, not the actual position of the view.

In this release, the view's actual position is not available to the application. This feature will be added to a future release.

If you need one or more of the layout properties to be updated after animation, you can update them in the callback after animation is complete. For example:

var newTop = view1.top - 100;
view1.animate({ top: newTop, duration: 500 }, function () {
    view.top = newTop; 
});
