[gtkmm] GnomeCanvas...........

["Suresh Kumar" <suresh_vsamy rediffmail com>]

Hi,

   Iam really confused with the use of "GnomeCanvas". Let me 
explain my doubts.

   When i read a document, i came to know that "GnomeCanvas" is 
contained in "GtkLayout". But when i searched gnome.h (I installed 
gtkmm,gtk+) in my system, no such header file was found.

    1. Is this means "GnomeCanvas" is not a part of Gtkmm ?
    2. Usually we use GtkWindow as a form where all other 
controls (like buttons,menus, etc) are placed. If GnomeCanvas is 
used as a container, how far it is better than GtkWindow?
    3. Is there any relationship between "GnomeCanvas" and 
"libgnomecanvas"?
    4. Where can i get "GnomeCanvas"?

    The following is regarding Gtkmm.

     Is it possible to scale or zoom the window and objects drawn 
(like rectangle,circles) in the gtkwindow? My application should 
support zoomin/zoomout.

Regrads,
Suresh.
