Starting in R2014b,
copyobj does not copy
callback properties or application data associated with graphics objects.
The copied object has callbacks set to empty character arrays and
application data set to empty structure arrays. Copies of objects
might not behave as expected. For example, clicking a push button
on the copy of a uicontrol has no effect.
If you want to create a copy of an object that has callbacks, then rerun the code used to create the first object to create a second object.
If you have existing code that uses
copy callbacks, then you can use
'legacy' option, for example,
copyobj(h,p,'legacy'). The behavior of the
is consistent with versions of MATLAB® before R2014b.
