# 需要导入模块: from forms import Form [as 别名]
# 或者: from forms.Form import add_field [as 别名]

"""
Parameters:
mt (:py:class:`Minitel`): the Minitel instance
title (str or list of str): the menu title, displayed centered on the screen
choices (list of str): the options
prompt (str): the prompt displayed with the input field. Default: "Your choice"
line_skip (int): vertical space between options. Default (0) places options on consecutive lines
margin_top (int): vertical space before the menu title. Default: 0
prompt_line (int): line number on which the input prompt is displayed
addit (list of tuple): additional prompts as a list of (x, y, text) tuples
cancelable (bool): if True, the cancel key (SOMMAIRE) can be used, and `get_choice` will exit
and return None. If False, the cancel key will be treated as an invalid choice.
