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:



  

  
Specifies the prefix of a Tcl command to invoke when the user closes the
      dialog. The actual command consists of string followed by a space
      and the name of the button clicked by the user to close the dialog. This
      is only available on macOS.

  

  
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.

  

  
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.

  

  
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.

      an empty string.

      is displayed on top of its parent window.

      value is an empty string.
