"""This module contains an object that represents a Telegram ReplyKeyboardRemove."""
from telegram import ReplyMarkup


class ReplyKeyboardRemove(ReplyMarkup):
    """
    Upon receiving a message with this object, Telegram clients will remove the current custom
    keyboard and display the default letter-keyboard. By default, custom keyboards are displayed
    until a new keyboard is sent by a bot. An exception is made for one-time keyboards that are
    hidden immediately after the user presses a button (see :class:`telegram.ReplyKeyboardMarkup`).

    Attributes:
        remove_keyboard (:obj:`True`): Requests clients to remove the custom keyboard.
        selective (:obj:`bool`): Optional. Use this parameter if you want to remove the keyboard
            for specific users only.

    Example:
        A user votes in a poll, bot returns confirmation message in reply to the vote and removes
        the keyboard for that user, while still showing the keyboard with poll options to users who
        haven't voted yet.

    Args:
        selective (:obj:`bool`, optional): Use this parameter if you want to remove the keyboard
            for specific users only. Targets:

            1) users that are @mentioned in the text of the Message object
            2) if the bot's message is a reply (has reply_to_message_id), sender of the original
               message.

        **kwargs (:obj:`dict`): Arbitrary keyword arguments.
