This procedure creates and displays a message window with an applica‐
tion-specified message, an icon and a set of buttons. Each of the but‐
tons in the message window is identified by a unique symbolic name (see
the -type options). After the message window is popped up, tk_message‐
Box waits for the user to select one of the buttons. Then it returns
the symbolic name of the selected button.
The following option-value pairs are supported:
-default name

sage window ('ok', 'cancel', and so on). See -type for a list of
the symbolic names. If the message box has just one button it
will automatically be made the default, otherwise if this option
is not specified, there won't be any default button.

lowing: error, info, question or warning. If this option is not
specified, then no icon will be displayed.
