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 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
              Name gives the symbolic name of the default button for this mes-
              sage 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.

       -icon iconImage
              Specifies  an icon to display. IconImage must be one of the fol-
              lowing: 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.

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