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
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:
- -command
string
- 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.
- -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. 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
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. 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.
