    :param title: the text positioned at the top of the window in larger font. If ``None``, a default localized title
                  is used. If not ``None`` or a string, will use the string representation of the object.
    :param message: the text positioned below the `title` in smaller font. If not a string, will use the string
                    representation of the object.
    :param ok: the text for the "ok" button. Must be either a string or ``None``. If ``None``, a default
               localized button title will be used.
    :param cancel: the text for the "cancel" button. If a string, the button will have that text. If `cancel`
                   evaluates to ``True``, will create a button with text "Cancel". Otherwise, this button will not be
                   created.
    :return: a number representing the button pressed. The "ok" button is ``1`` and "cancel" is ``0``.
