Re: [Pgu-devel] Dialog close on Esc

[Phil H. <phi...@ya...>]

Ethan,
 
 Thanks for the patch, I'll see about adding it in for the next release.  (I've added it to changes.txt as a reminder to myself.)
 
 With any luck, I'll be doing a new release with a handful of bug fixes and a few cleanup changes.
 
 Thanks!
 Phil

I see in the archives that this feature was suggested and a patch
requested but never supplied (at least in SVN revision 15). I'm
attaching one based on my (admittedly limited) understanding of the
library. Is this the way to do this?
