[plt-scheme] obtaining list of opened files in DrScheme
Hi there,
I posted about this issue some months ago. I want to extend DrScheme
with a change buffer dialog. Guillaume Marceau was kind enough to
point me to some example code [1], which seems to indicate that I have
to transverse some objects, beginning at the editor<%> argument that
is passed to my event handler, until I find someone that has the list
of open files. Unfortunately, I don't know my way around the framework
very well. Can anyone point me in the right direction?
Thanks in advance,
-pp
