[pygtk] Installing and switching themes in pygtk

[David Hirschfield]

I'm a newbie to pygtk and gtk programming in general...so forgive these 
very basic questions:

1. Where does a person find gtk themes? Is there a good clearing house 
website?
2. Do all gtk themes work with pygtk? I would assume so...as long as the 
theme is for the version of gtk and pygtk you're using.
3. How does one install new gtk themes? Do they have to be installed in 
a specific directory? If so, where?
4. How can a pygtk program change the gtk theme used to draw itself? Can 
it be done programmatically from within the pygtk program that wants to 
set its theme?

I'm asking because we have a pygtk app that needs to be able to switch 
themes on the fly depending on certain user choices. But we don't want 
it to affect all pygtk apps, just the one the user makes the choice in.

Any pointers appreciated,
-Dave
