There are two approaches:


a)  If you have mostly text with a few images, you'll want to use a  
GtkTextView (Gtk2::TextView in gtk2-perl) and learn how to embed  
pictures and modify things with tags.  The GtkTextView is modeled after  
the Tk Text widget, so you should feel at home.

There don't appear to be a lot of tutorials about the TextView on the  
web, but gtk-demo includes some code that test drives it pretty well.
http://cvs.sourceforge.net/viewcvs.py/gtk2-perl/gtk2-perl-xs/Gtk2/gtk- 
demo/textview.pl?rev=1.12&view=auto



b)  If you have mostly graphical components, you will be more  
interested in GnomeCanvas (Gnome2::Canvas in gtk2-perl, distributed as  
a separate module).  GnomeCanvas is, again, modeled after its Tk  
counterpart; it is distributed separately because libgnomecanvas its  
anti-aliased mode uses libart, whereas gtk+ avoids this dependency.

Most information i could find about the gnome canvas on the web dates  
from gnome 1.x, but you're in luck, because it has barely changed since  
then:
