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 <examples.inlinekeyboard>`
* :any:`Inline Keyboard 2 <examples.inlinekeyboard2>`
.. 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=<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=<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
:tg-const:`telegram.InlineKeyboardButton.MIN_CALLBACK_DATA`-
:tg-const:`telegram.InlineKeyboardButton.MAX_CALLBACK_DATA` bytes.
Not supported for messages sent on behalf of a Telegram Business account.
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:: :wiki:`Arbitrary callback_data <Arbitrary-callback_data>`
web_app (:obj:`telegram.WebAppInfo`, optional): Description of the `Web App
<https://core.telegram.org/bots/webapps>`_ 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. Not supported for messages sent on behalf of
a Telegram Business account.
.. versionadded:: 20.0
switch_inline_query (: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. May 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. Not supported in channels and for
messages sent on behalf of a Telegram Business account.
Tip:
This is similar to the new parameter :paramref:`switch_inline_query_chosen_chat`,
but gives no control over which chats can be selected.
switch_inline_query_current_chat (:obj:`str`, optional): If set, pressing the button will
prompt the user to select one of their chats of the specified type, open that chat and
insert the bot's username and the specified inline query in the input field. Not
supported for messages sent on behalf of a Telegram Business account.
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.
switch_inline_query_chosen_chat (:obj:`telegram.SwitchInlineQueryChosenChat`, optional):
If set, pressing the button will prompt the user to select one of their chats of the
specified type, open that chat and insert the bot's username and the specified inline
query in the input field. Not supported for messages sent on behalf of a Telegram
Business account.
.. versionadded:: 20.3
Tip:
This is similar to :paramref:`switch_inline_query`, but gives more control on
which chats can be selected.
Caution:
The PTB team has discovered that this field works correctly only if your Telegram
client is released after April 20th 2023.
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=<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
