tree-widget-themes-load-path

tree-widget-themes-load-path is a variable defined in `tree-widget.el'.
Its value is shown below.

Documentation:
List of locations in which to search for the themes sub-directory.
Each element is an expression that will be recursively evaluated until
it returns a single directory or a list of directories.
The default is to search in the `load-path' first, then in the
"images" sub directory in the data directory, then in the data
directory.
The data directory is the value of the variable `data-directory' on
Emacs, and what `(locate-data-directory "tree-widget")' returns on
XEmacs.

Value:

(load-path
 (let
     ((dir
       (if
	   (fboundp 'locate-data-directory)
	   (locate-data-directory "tree-widget")
	 data-directory)))
   (and dir
	(list dir
	      (expand-file-name "images" dir)))))
