Where is the code for desktop windows?

[leena chourey <leenagour gmail com>]

Hello list 

I am a new member of this list. I have tried to explore nautilus firs time, b'coz I want to change something to desktop window.

As explored and found:  (please confirm)

• Desktop is part of nautilus.  Frame named: x-nautilus-desktop           Is it?
  
• It is a GTK widget : frame  .    Is it?
  
• It displays content of desktop directory shown in file manager?  Is it?
  

Now how can I know, how nautilus renders desktop window, icon positions, method of icon display (row* column or pixel bases) and other details?
I have downloaded the source code of nautilus-2.28.1 from gnome site and trying to understand the details. As explored and found that nautilus-desktop-window.c, .h can give useful things required.

Please help me in understanding desktop and nautilus.

Thanks & regards
