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
return the symbolic name of the button the user pressed, as a string (such as
or
). Common message box styles and layouts include but are not limited to:
classtkinter.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:
commandSpecifies 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.
defaultGives the
of the default button for this message window (
,
, and so on). If this option is not specified, the first button in the dialog will be made the default.
detailSpecifies 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.
iconSpecifies an
to display. If this option is not specified, then the
icon will be displayed.
messageSpecifies the message to display in this message box. The default value is an empty string.
parentMakes the specified window the logical parent of the message box. The message box is displayed on top of its parent window.
titleSpecifies 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.
typeArranges for a
to be displayed.
Note
Tk 8.6 added the command option.
