"""This module contains an object that represents a Telegram InlineKeyboardButton.""" from typing import TYPE_CHECKING, Optional, Union from telegram._games.callbackgame import CallbackGame from telegram._loginurl import LoginUrl from telegram._telegramobject import TelegramObject from telegram._utils.types import JSONDict from telegram._webappinfo import WebAppInfo if TYPE_CHECKING: from telegram import Bot class InlineKeyboardButton(TelegramObject): """This object represents one button of an inline keyboard. Objects of this class are comparable in terms of equality. Two objects of this class are considered equal, if their :attr:`text`, :attr:`url`, :attr:`login_url`, :attr:`callback_data`, :attr:`switch_inline_query`, :attr:`switch_inline_query_current_chat`, :attr:`callback_game`, :attr:`web_app` and :attr:`pay` are equal. Note: * You must use exactly one of the optional fields. Mind that :attr:`callback_game` is not working as expected. Putting a game short name in it might, but is not guaranteed to work. * If your bot allows for arbitrary callback data, in keyboards returned in a response from telegram, :attr:`callback_data` maybe be an instance of :class:`telegram.ext.InvalidCallbackData`. This will be the case, if the data associated with the button was already deleted. .. versionadded:: 13.6 * Since Bot API 5.5, it's now allowed to mention users by their ID in inline keyboards. This will only work in Telegram versions released after December 7, 2021. Older clients will display *unsupported message*. Warning: * If your bot allows your arbitrary callback data, buttons whose callback data is a non-hashable object will become unhashable. Trying to evaluate ``hash(button)`` will result in a :class:`TypeError`. .. versionchanged:: 13.6 * After Bot API 6.1, only ``HTTPS`` links will be allowed in :paramref:`login_url`. Examples: * :any:`Inline Keyboard 1 ` * :any:`Inline Keyboard 2 ` .. seealso:: :class:`telegram.InlineKeyboardMarkup` .. versionchanged:: 20.0 :attr:`web_app` is considered as well when comparing objects of this type in terms of equality. Args: text (:obj:`str`): Label text on the button. url (:obj:`str`, optional): HTTP or tg:// url to be opened when the button is pressed. Links ``tg://user?id=`` can be used to mention a user by their ID without using a username, if this is allowed by their privacy settings. .. versionchanged:: 13.9 You can now mention a user using ``tg://user?id=``. login_url (:class:`telegram.LoginUrl`, optional): An ``HTTPS`` URL used to automatically authorize the user. Can be used as a replacement for the Telegram Login Widget. Caution: Only ``HTTPS`` links are allowed after Bot API 6.1. callback_data (:obj:`str` | :obj:`object`, optional): Data to be sent in a callback query to the bot when button is pressed, UTF-8 1-64 bytes. If the bot instance allows arbitrary callback data, anything can be passed. Tip: The value entered here will be available in :attr:`telegram.CallbackQuery.data`. .. seealso:: `Arbitrary callback_data `_ web_app (:obj:`telegram.WebAppInfo`, optional): Description of the `Web App `_ that will be launched when the user presses the button. The Web App will be able to send an arbitrary message on behalf of the user using the method :meth:`~telegram.Bot.answer_web_app_query`. Available only in private chats between a user and the bot. .. versionadded:: 20.0 switch_inline_query (:obj:`str`, optional): If set, pressing the button will prompt the user to select one of their chats, open that chat and insert the bot's username and the specified inline query in the input field. Can be empty, in which case just the bot's username will be inserted. This offers an easy way for users to start using your bot in inline mode when they are currently in a private chat with it. Especially useful when combined with switch_pm* actions - in this case the user will be automatically returned to the chat they switched from, skipping the chat selection screen. switch_inline_query_current_chat (:obj:`str`, optional): If set, pressing the button will insert the bot's username and the specified inline query in the current chat's input field. Can be empty, in which case only the bot's username will be inserted. This offers a quick way for the user to open your bot in inline mode in the same chat - good for selecting something from multiple options. callback_game (:class:`telegram.CallbackGame`, optional): Description of the game that will be launched when the user presses the button. This type of button must always be the ``first`` button in the first row. pay (:obj:`bool`, optional): Specify :obj:`True`, to send a Pay button. This type of button must always be the `first` button in the first row and can only be used in invoice messages. Attributes: text (:obj:`str`): Label text on the button. url (:obj:`str`): Optional. HTTP or tg:// url to be opened when the button is pressed. Links ``tg://user?id=`` can be used to mention a user by their ID without using a username, if this is allowed by their privacy settings. .. versionchanged:: 13.9 You can now mention a user using ``tg://user?id=``. login_url (:class:`telegram.LoginUrl`): Optional. An ``HTTPS`` URL used to automatically authorize the user. Can be used as a replacement for the Telegram Login Widget. Caution: Only ``HTTPS`` links are allowed after Bot API 6.1. callback_data (:obj:`str` | :obj:`object`): Optional. Data to be sent in a callback query to the bot when button is pressed, UTF-8 1-64 bytes. web_app (:obj:`telegram.WebAppInfo`): Optional. Description of the `Web App `_ that will be launched when the user presses the button. The Web App will be able to send an arbitrary message on behalf of the user using the method :meth:`~telegram.Bot.answer_web_app_query`. Available only in private chats between a user and the bot. .. versionadded:: 20.0 switch_inline_query (:obj:`str`): Optional. Will prompt the user to select one of their chats, open that chat and insert the bot's username and the specified inline query in the input field. Can be empty, in which case just the bot's username will be inserted. switch_inline_query_current_chat (:obj:`str`): Optional. Will insert the bot's username and the specified inline query in the current chat's input field. Can be empty, in which case just the bot's username will be inserted. callback_game (:class:`telegram.CallbackGame`): Optional. Description of the game that will be launched when the user presses the button. pay (:obj:`bool`): Optional. Specify :obj:`True`, to send a Pay button.
