NAME
tk_messageBox - pops up a message window and waits for user response.
 
SYNOPSIS
tk_messageBox ?option value ...?
 
DESCRIPTION
This procedure creates and displays 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).  After the message window is
popped up, tk_messageBox 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
- 
Name gives the symbolic name of the default button for
this message window (
``ok'',

the first button in the dialog will be made the default.

following: error, info, question or
warning. If this option is not specified, then the info icon will be
displayed.
