* SECTION: gimppatheditor
* @title: GimpPathEditor
* @short_description: Widget for editing a file search path.
* @see_also: #GimpFileEntry, #G_SEARCHPATH_SEPARATOR
*
* This widget is used to edit file search paths.
*
* It shows a list of all directories which are in the search
* path. You can click a directory to select it. The widget provides a
* #GimpFileEntry to change the currently selected directory.
*
* There are buttons to add or delete directories as well as "up" and
* "down" buttons to change the order in which the directories will be
* searched.
*
* Whenever the user adds, deletes, changes or reorders a directory of
* the search path, the "path_changed" signal will be emitted.
