and a set of buttons.
Each of the buttons in the message window is identified by a unique symbolic name (see the <em>type</em> options).</p>
<p>The following options are supported:</p>
<blockquote>
<div><dl class="simple">
<dt><em>command</em></dt><dd><p>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.</p>

If this option is not specified, the first button in the dialog will
be made the default.</p>
</dd>
<dt><em>detail</em></dt><dd><p>Specifies an auxiliary message to the main message given by the
<em>message</em> 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.</p>
</dd>
<dt><em>icon</em></dt><dd><p>Specifies an <a class="reference internal" href="#messagebox-icons"><span class="std std-ref">icon</span></a> to display.
If this option is not specified, then the <a class="reference internal" href="#tkinter.messagebox.INFO" title="tkinter.messagebox.INFO"><code class="xref py py-data docutils literal notranslate"><span class="pre">INFO</span></code></a> icon will be
displayed.</p>
</dd>
<dt><em>message</em></dt><dd><p>Specifies the message to display in this message box.
The default value is an empty string.</p>
</dd>
<dt><em>parent</em></dt><dd><p>Makes the specified window the logical parent of the message box.
The message box is displayed on top of its parent window.</p>
</dd>
<dt><em>title</em></dt><dd><p>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.</p>
