NAME

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",  "cancel",
              and  so on). See -type for a list of the symbolic names.  If this option is not specified, the
              first button in the dialog will be made the default.

       -detail string
              Specifies an auxiliary message to the main message given by the -message option.   Where  sup- |
              ported  by  the  underlying OS, the message detail will be presented in a less emphasized font |
              than the main message.

       -icon iconImage
              Specifies an icon to display. IconImage must be one of the following: error, info, question or
              warning. If this option is not specified, then the info icon will be displayed.

       -message string
              Specifies the message to display in this message box.

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

       -title titleString
              Specifies a string to display as the title of the message box. The default value is  an  empty
              string.

       -type predefinedType
              Arranges  for  a  predefined set of buttons to be displayed. The following values are possible
              for predefinedType:

              abortretryignore  Displays three buttons whose symbolic names are abort, retry and ignore.

              ok                Displays one button whose symbolic name is ok.

              okcancel          Displays two buttons whose symbolic names are ok and cancel.

              retrycancel       Displays two buttons whose symbolic names are retry and cancel.

              yesno             Displays two buttons whose symbolic names are yes and no.
