Thanks.  For the record I ended up with this:

	"(file|http|ftp|https)://([-0-9a-zA-Z\\._]*)(:[0-9]+)?([-/\\.a-zA-Z0-9_#~:.?+=&%!@]*)"


which handles URLs like all of these, and others:

	http://example.com
	http://example.com/dirname
	http://example.com/dirname/file.ext
	http://example.com:8080/dirname

	etc.

I got a little confused along the way because apparently wxRegEx doesn't 
support the common \w character class and I had used when experimenting 
with regex's in Python.  I kept getting non-matches when I thought I had 
done everything right, so I thought maybe my regex skills were a lot 
more rusty than I thought...
