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:

-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.

EXAMPLE

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}
}
