Variable: gnus-group-icon-list
gnus-group-icon-list is a customizable variable defined in
gnus-group.el.gz.
Value
nil
Documentation
Controls the insertion of icons into group buffer lines.
Below is a list of Form/File pairs. When deciding how a
particular group line should be displayed, each form is evaluated.
The icon from the file field after the first true form is used. You
can change how those group lines are displayed by editing the file
field. The File will either be found in the
gnus-group-glyph-directory or by designating absolute name of the
file.
It is also possible to change and add form fields, but currently that
requires an understanding of Lisp expressions. Hopefully this will
change in a future release. For now, you can use the same
variables in the Lisp expression as in gnus-group-highlight.
