class Button:

|
"""
|
|
.. note::
|
|
|
|
This class is used to **define** reply markups, e.g. when
|
|
sending a message or replying to events. When you access
|
|
`Message.buttons <telethon.tl.custom.message.Message.buttons>`
|
|
they are actually `MessageButton
|
|
<telethon.tl.custom.messagebutton.MessageButton>`,
|
|
so you might want to refer to that class instead.
|
|
|
|
Helper class to allow defining ``reply_markup`` when
|
|
sending a message with inline or keyboard buttons.
|
|
|
|
You should make use of the defined class methods to create button
|
|
instances instead making them yourself (i.e. don't do ``Button(...)``
|
|
but instead use methods line `Button.inline(...) <inline>` etc.
|
|
|
|
You can use `inline`, `switch_inline`, `url` and `auth`
|
|
together to create inline buttons (under the message).
|
|
|
|
You can use `text`, `request_location`, `request_phone` and `request_poll`
|
|
together to create a reply markup (replaces the user keyboard).
|
|
You can also configure the aspect of the reply with these.
|
|
The latest message with a reply markup will be the one shown to the user
|
|
(messages contain the buttons, not the chat itself).
|
|
|
|
You **cannot** mix the two type of buttons together,
|
|
and it will error if you try to do so.
|
|
|
|
The text for all buttons may be at most 142 characters.
|
|
If more characters are given, Telegram will cut the text
|
|
to 128 characters and add the ellipsis (…) character as
|
|
the 129.
