I am making a theme very specifically fitted to my wants (Gnome, Ubuntu 8.04), and I would like to know some common classes/widget names that are used in the panel. Specifically:
  • Panel background
  • Window list
  • Dividers
  • Main Menu button
I would like these so I can change them to have specific looks. The reason I need the menu button is that without manually stating normal, over, down etc. states all one can do is change the icon is uses, which when using certain panel sizes does not work properly.

Does anyone happen to know these? In addition, if you happen to know a way I can set spacing between tabs (without editing the image) it would be much appreciated!

P.S.: Using Gnome, Ubuntu 8.04, and pixmap engine for everything.
