[reportlab-users] links to other pdfs ...

[Larry Bates]

Below is some code that allows you to imbed any http://
link in .PDF file.  This could point to .PDF (either
locally with file:// or remotely with http://.

Hope it helps.

Hello,

I am  just starting to get to know reportlab, and it has been very good so =
far.  I am just having an issue creating "links" that either switch the c=
urrent document or open another document in another adobe window.  Maybe =
I am not reading the manual correctly, but it appears that this functiona=
lity isn't there yet.  I don't really know PDF specs, but have programmed=
 python and postscript before, so I might be able to impliment it if it c=
urrently doesn't exist (although hints about how to do it would be greatl=
y appreciated)

Thanks,
Jesse
