Description copied from interface: LayoutAssistant

Optionally modify size and position of an object being moved to conform to the constraints imposed by the LayoutManager being represented. This method may be called from the UIEditor during a move operation such that it may provide dynamic feedback to the user depicting the expected bounds of the object throughout the operation.
