PropListener - add a callback to property value get/set event

Attach a listener callback to a property value get/set event(s)

Description

This is an enhancement of Matlab's hidden and unsupported addlistener function (within the uitools folder). It attaches a listener callback to one or more property (or properties) get or set event(s).

Acceptable events are PreGet, PreSet, PostGet and PostSet, which are triggered immediately before/after a get/set event on a handle property value.

Example:
proplistener(gcf,{'Visible','NumberTitle'},{'PreGet','postSet'},@myFunc)

See more extensive help section within.

Note: relies on undocumented and unsupported Matlab functionality. Use at your own risk. Comments welcome

I was able to use this function to update a graph every time the x-axis changed, without knowing much about how listeners work.

Once again Yair saves a lot of frustration with his instructive and well written code. Until I get R2008 up this function nicely does the trick.

In my case coordinating the 'EdgeColo'r of a patch and a line's 'Color' property. Something linkprop can't do.
