- class tkinter.messagebox.Message(master=None, **options)¶

The following options are supported:

Specifies the function to invoke when the user closes the dialog. The name of the button clicked by the user to close the dialog is passed as argument. This is only available on macOS.
- default
Gives the symbolic name of the default button for this message window (
OK
,CANCEL
, and so on). If this option is not specified, the first button in the dialog will be made the default.- detail
Specifies an auxiliary message to the main message given by the message option. The message detail will be presented beneath the main message and, where supported by the OS, in a less emphasized font than the main message.

Specifies an icon to display. If this option is not specified, then the
INFO
