Is it possible to programmatically cancel a resize?

Is it possible to programmatically cancel a resize?


I'm working with a grid of divs that are both resizable and draggable.
I want to limit the resizing so you can't make one div overlap
another. Kind of like containment, except the other objects are
siblings to the one being resized, not parents.
The only thing I can think of would be to monitor the resize events
during the resize and cancel it if the mouse moves into another div.
But I can't figure out how one would programmatically cancel the
resize.
Any ideas?
