[pygtk] Flashing widget background

[Peter Brooks]

Hi all,
I'm looking to getting widgets in my program to flash, such as ardour
does for it's record button.

Currently my thinking is to create a new thread to keep changing the
background colour. However I'm trying to find out if there's already
implementations of this out there.

 I've looked at ardour's but I am finding tracing how they do it
taking quite a bit of time given their project maturity.

Cheers
