                                                         GtkWidget *window);
  The ThunarxPreferencesProvider interface is implemented by extensions that
  want to register additional actions in the preferences menu of the file
  manager. In general this should only be done by extensions that are closely
  tied to the file manager (for example, the thunar-uca is
  such an extension, while an extension that just adds  and  to the
  context menu of compressed files should not add their own preferences to
  the file manager menu, because it should use desktop-wide settings for
  archive managers instead).
  The GtkActions returned from the
  thunarx_preferences_provider_get_actions() method must be namespaced with the
  model to avoid collision with internal file manager actions and actions provided
  by other extensions. For example, the preferences action provided by the
  thunar-uca extension is called
  ThunarUca::manage-actions.

Interface with virtual methods implementation by extensions that want to install preferences actions in the file managers menu.
Providers don't need to implement all of the virtual methods listed in the interface.
typedef struct _ThunarxPreferencesProvider ThunarxPreferencesProvider;
Preferences provider type.
GList * thunarx_preferences_provider_get_actions (ThunarxPreferencesProvider *provider,GtkWidget *window);
Returns the list of GtkActions that provider has to offer
as preferences within window. These actions will usually be added
to the builtin list of preferences in the "Edit" menu of the file
manager's window.
Plugin writers that implement this interface should make sure to choose descriptive action names and tooltips, and not to crowd the "Edit" menu too much. That said, think twice before implementing this interface, as too many preference actions will render the file manager useless over time!
The caller is responsible to free the returned list of actions using something like this when no longer needed:
| 1 2 | g_list_foreach (list, (GFunc) g_object_unref, NULL); g_list_free (list); | 
| 
 | a ThunarxPreferencesProvider. | 
| 
 | the GtkWindow within which the actions will be used. | 
| Returns : | the list of GtkActions that providerhas
              to offer as preferences withinwindow. |
