tk_messageBox(1t)            Tk Built-In Commands            tk_messageBox(1t)


       tk_messageBox - pops up a message window and waits for user response.

       tk_messageBox ?option value ...?

       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.

       -detail string
              Specifies  an auxiliary message to the main message given by the
              -message 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.

       -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.  The
              default value is an empty string.

       -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.
              This  option  is  ignored on Mac OS X, where platform guidelines
              forbid the use of a title on this kind of dialog.

       -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.

              yesnocancel       Displays  three  buttons  whose symbolic names
                                are yes, no and cancel.

              set answer [tk_messageBox -message "Really quit?" \
                      -icon question -type yesno \
                      -detail "Select \"Yes\" to make the application exit"]
              switch -- $answer {
                  yes exit
                  no {tk_messageBox -message "I know you like this application!" \
                          -type ok}
