The :class:`Dialog` widgets
===========================

This section describes all widgets (or dialog boxes) offered by the
:class:`Dialog` class. The descriptions of many of them are adapted from the
:manpage:`dialog(1)` manual page, with the kind permission of `Thomas Dickey
<http://invisible-island.net/>`_.


.. note::

  All unqualified method names in this section are methods of the
  :class:`Dialog` class. In other words, whenever a method :meth:`!foo` is
  mentioned, you have to understand :meth:`!dialog.Dialog.foo`.

.. warning::

  Concerning the older widgets that have fixed defaults for the length
  parameters such as *width* and *height*:

  Even though explicitely setting one of these length parameters to ``None``
  will not cause any error in this version, please don't do it. If you know
  the size you want, specify it directly (e.g., ``width=78``). On the other
  hand, if you want :program:`dialog` to automagically figure out a suitable
  size, you have two options:

    - either enable the :ref:`autowidgetsize <autowidgetsize>` option and
      make sure not to specify the length parameter in the widget call;
    - or explicitely set it to ``0`` (e.g., ``width=0``).
