  41  * @short Provides a list view of domains which policies are attached to.

  43  * This class resembles a list view of domain names and some buttons to
  44  * manipulate it. You should use this widget if you need to manage domains
  45  * whose policies are described by (derivatives of) Policies objects.
  46  *
  47  * The contained widgets can be accessed by respective getters for
  48  * fine-tuning/customizing them afterwards.
  49  *
  50  * To use this class you have to derive your own and implement most
  51  * (all) of the protected methods. You need these to customize this widget
  52  * for its special purpose.
