exactly one of the optional fields.

Objects of this class are comparable in terms of equality. Two objects of this class are
|
|
considered equal, if their :attr:`text`, :attr:`web_app` and :attr:`start_parameter` are equal.
|
|
|
|
Args:
|
|
text (:obj:`str`): Label text on the button.
|
|
web_app (:class:`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 switch back to the inline mode
|
|
using the method
|
|
`switchInlineQuery <https://core.telegram.org/bots/webapps#initializing-web-apps>`_
|
|
inside the Web App.
|
|
start_parameter (:obj:`str`, optional): Deep-linking parameter for the
|
|
:guilabel:`/start` message sent to the bot when user presses the switch button.
|
|
:tg-const:`telegram.InlineQuery.MIN_SWITCH_PM_TEXT_LENGTH`-
|
|
:tg-const:`telegram.InlineQuery.MAX_SWITCH_PM_TEXT_LENGTH` characters,
|
|
only ``A-Z``, ``a-z``, ``0-9``, ``_`` and ``-`` are allowed.
|
|
|
|
Example:
|
|
An inline bot that sends YouTube videos can ask the user to connect the bot to
|
|
their YouTube account to adapt search results accordingly. To do this, it displays
|
|
a 'Connect your YouTube account' button above the results, or even before showing
|
|
any. The user presses the button, switches to a private chat with the bot and, in
|
|
doing so, passes a start parameter that instructs the bot to return an OAuth link.
|
|
Once done, the bot can offer a switch_inline button so that the user can easily
|
|
return to the chat where they wanted to use the bot's inline capabilities.
|
|
|
|
Attributes:
|
|
text (:obj:`str`): Label text on the button.
|
|
web_app (:class:`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 switch back to the inline mode
|
|
using the method ``web_app_switch_inline_query`` inside the Web App.
|
|
start_parameter (:obj:`str`): Optional. Deep-linking parameter for the
|
|
:guilabel:`/start` message sent to the bot when user presses the switch button.
|
|
:tg-const:`telegram.InlineQuery.MIN_SWITCH_PM_TEXT_LENGTH`-
|
|
:tg-const:`telegram.InlineQuery.MAX_SWITCH_PM_TEXT_LENGTH` characters,
