"""This object represents a custom keyboard with reply options.
|
|
|
|
Attributes:
|
|
keyboard (List[List[:class:`telegram.KeyboardButton` | :obj:`str`]]): Array of button rows.
|
|
resize_keyboard (:obj:`bool`): Optional. Requests clients to resize the keyboard.
|
|
one_time_keyboard (:obj:`bool`): Optional. Requests clients to hide the keyboard as soon as
|
|
it's been used.
|
|
selective (:obj:`bool`): Optional. Show the keyboard to specific users only.
|
|
|
|
Example:
|
|
A user requests to change the bot's language, bot replies to the request with a keyboard
|
|
to select the new language. Other users in the group don't see the keyboard.
|
|
|
|
Args:
|
|
keyboard (List[List[:obj:`str` | :class:`telegram.KeyboardButton`]]): Array of button rows,
|
|
each represented by an Array of :class:`telegram.KeyboardButton` objects.
|
|
resize_keyboard (:obj:`bool`, optional): Requests clients to resize the keyboard vertically
|
|
for optimal fit (e.g., make the keyboard smaller if there are just two rows of
|
|
buttons). Defaults to false, in which case the custom keyboard is always of the same
|
|
height as the app's standard keyboard. Defaults to ``False``
|
|
one_time_keyboard (:obj:`bool`, optional): Requests clients to hide the keyboard as soon as
|
|
it's been used. The keyboard will still be available, but clients will automatically
|
|
display the usual letter-keyboard in the chat - the user can press a special button in
|
|
the input field to see the custom keyboard again. Defaults to ``False``.
|
|
selective (:obj:`bool`, optional): Use this parameter if you want to show the keyboard to
|
|
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.
|
|
|
|
Defaults to ``False``.
|
|
|
|
**kwargs (:obj:`dict`): Arbitrary keyword arguments.
