OK, I've been using XFCE for almost two years now (and loving it more and more).
So I'll just give a rundown on what you're installing and where to "see" it.
First off, there's a Window Decoration theme. This theme affects how your X windows look. In a default XFCE installation, the Window Decoration themes are located at /usr/share/xfwm4/themes
Secondly, there are User Interface themes. These themes affect how your panels, buttons and other UI gadgets look and behave. They are also known as GTK themes
, and are used in Gnome (and probably other GTK based DEs) as well. They are located at /usr/share/themes
How to tell which is which? Well GTK themes usually contain directories called gtk/
in them. The should also contain an index.theme
XFCE window decoration themes contain lots of *.xpm
images which form the look of the window decoration. The file names are also descriptive, ie.: bottom-right-active.xpm, bottom-right-inactive.xpm, close-active.xpm, close-inactive.xpm, etc.
Hope this helps
