Thread Subject:

Callback function for changes of figure properties

Hi all,
I would like to set a callback function that is called whenever any property of a certain figure is changed (eg. if a the 'color' or 'position' property has changed, etc.). There is probably a Java-based solution. However, I couldn't figure it out so far. Any suggestions?
Cheers,
Adrian

You can use the PropListener utility from the Matlab File Exchange:

PropListener uses the undocumented handle.listener function, which is described here:
