[reportlab-users] Example, please: putting TOC at the beginning

[Aaron Watters]

Well, if you know how many pages are in the toc you can put the toc into 
one or more forms
-- "draw" the forms at the beginning of the process and then "define" 
them at the end (forms
are lazy and may be defined after they have been referenced).  Just to 
be confusing I'm talking about
"PDF xform objects" defined in reportlab using canvas.beginForm ... 
canvas.endForm, not
"Adobe forms" which are not yet supported in reportlab... not just 
yet... ;).
