示例1: __init__

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

            and return None. If False, the cancel key will be treated as an invalid choice.
