"""This object represents a custom keyboard with reply options.
|
|
|
|
Objects of this class are comparable in terms of equality. Two objects of this class are
|
|
considered equal, if their the size of :attr:`keyboard` and all the buttons are equal.
|
|
|
|
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 :obj:`False`, in which case the custom keyboard is always of the
|
|
same height as the app's standard keyboard.
|
|
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 :obj:`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 :attr:`~telegram.Message.text` of the
|
|
:class:`telegram.Message` object.
|
|
2) If the bot's message is a reply (has ``reply_to_message_id``), sender of the
|
|
original message.
|
|
|
|
Defaults to :obj:`False`.
|
|
|
|
input_field_placeholder (:obj:`str`, optional): The placeholder to be shown in the input
|
|
field when the keyboard is active; 1-64 characters.
|
|
|
|
.. versionadded:: 13.7
|
|
|
|
**kwargs (:obj:`dict`): Arbitrary keyword arguments.

|
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
