Documentation

Name of the theme in which to look for images.

This is a sub directory of the themes directory specified by the tree-widget-themes-directory option. The default theme is "default". When an image is not found in a theme, it is searched in its parent theme.

A complete theme must at least contain images with these file names with a supported extension (see also tree-widget-image-formats):

"guide"
  A vertical guide line.
"no-guide"
  An invisible vertical guide line.
"end-guide"
  End of a vertical guide line.
"handle"
  Horizontal guide line that joins the vertical guide line to an icon.
"no-handle"
  An invisible handle.

Plus images whose name is given by the :glyph-name property of the icon widgets used to draw the tree. By default these images are used:

"open"
  Icon associated to an expanded tree.
"close"
  Icon associated to a collapsed tree.
"empty"
  Icon associated to an expanded tree with no child.
"leaf"
  Icon associated to a leaf node.
