Re: Example for doing gtk draw_string on a drawing area (newbie)

[Dov Grobgeld <dov imagic weizmann ac il>]

Hello Cameron,

I would recommend that you use the Gnome::Canvas instead for creating
your graphics. It is much simpler than to use the primitive gdk 
functions directly on a window. Since you are using Gtk-Perl-0.7008 then
see the Gnome/samples/canvas.pl directory for examples of how to 
create the various canvas objects. For a more complete description of the
canvas, see the GGAD book.

Regards,
Dov
