Documentation

In the current buffer, set the theme to use for images.

The current buffer must be where the tree widget is drawn. Optional argument NAME is the name of the theme to use. It defaults to the value of the variable tree-widget-theme. Does nothing if NAME is already the current theme.

If there is a "tree-widget-theme-setup" library in the theme directory, load it to setup a parent theme or the images properties. Typically it should contain something like this:

  (tree-widget-set-parent-theme "my-parent-theme")
  (tree-widget-set-image-properties
     '(:ascent center :mask (heuristic t)))
