adds the function handle id
= addNewPositionCallback(h
,fcn
)fcn

callback functions of the ROI object h
. Whenever the ROI object
changes its position, each function in the list is called with the
syntax:
fcn(pos)
pos
is of the form returned by the object's getPosition
method.
The return value, id
, is used only with removeNewPositionCallback
.
