"tkinter.messagebox" --- Tkinter message prompts#

Código fuente: Lib/tkinter/messagebox.py

======================================================================

The "tkinter.messagebox" module provides a template base class as well as a variety of convenience methods for commonly used configurations. The message boxes are modal: each blocks until the user responds, then returns a value that depends on the function. The "show*" functions and "Message.show()" return the symbolic name of the button the user pressed, as a string (such as "OK" or "YES"). Common message box styles and layouts include but are not limited to:

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

Create a message window with an application-specified message, an icon and a set of buttons. Each of the buttons in the message window is identified by a unique symbolic name (see the type options).

The following options are supported:

  *command*
     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.

  *icon*
     Specifies an icon to display. If this option is not
     specified, then the "INFO" icon will be displayed.

  *message*
     Specifies the message to display in this message box. The
     default value is an empty string.

  *parent*
     Makes the specified window the logical parent of the message
     box. The message box is displayed on top of its parent
     window.

  *title*
     Specifies a string to display as the title of the message
     box. This option is ignored on macOS, where platform
     guidelines forbid the use of a title on this kind of dialog.

  *type*
     Arranges for a predefined set of buttons to be displayed.

Nota:

 Tk 8.6 added the *command* option.
