quick question

[Chris Mazuc <chucker hempseed com>]

I would like to know how to get the default buttons like in the open
dialog. I found out how to do this once but forgot. I know you have to set
it defaultable first (I think, at least this is the way it used to work)
and then you make it the default, but I don't know the functions for
either and can't find them.
