tk_messageBox(3tk) Tk Built-In Commands tk_messageBox(3tk) 





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 Mac OS X.

  

  
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.

  

  
Specifies the message to display in this message box. The default value is
      an empty string.

  

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

  

  
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.

  

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







  

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

  

  
Displays one button whose symbolic name is ok.

  

  
Displays two buttons whose symbolic names are ok and
    cancel.

  

  
Displays two buttons whose symbolic names are retry and
      cancel.

  

  
Displays two buttons whose symbolic names are yes and
    no.

  

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