.SH NAME
tk_messageBox \- pops up a message window and waits for user response.
.SH SYNOPSIS
\fBtk_messageBox \fR?\fIoption value ...\fR?
.BE
.SH DESCRIPTION
.PP
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 \fB\-type\fR options).  After the message window is
popped up, \fBtk_messageBox\fR waits for the user to select one of the
buttons. Then it returns the symbolic name of the selected button.
.PP
The following option-value pairs are supported:
.TP
\fB\-command\fR \fIstring\fR
Specifies the prefix of a Tcl command to invoke when the user closes the
dialog. The actual command consists of \fIstring\fR followed by a space
and the name of the button clicked by the user to close the dialog. This
is only available on macOS.
.TP
\fB\-default\fR \fIname\fR
.
\fIName\fR gives the symbolic name of the default button for
this message window (
.QW ok ,
.QW cancel ,
and so on). See \fB\-type\fR
for a list of the symbolic names.  If this option is not specified,
the first button in the dialog will be made the default.
.TP
\fB\-detail\fR \fIstring\fR
.
Specifies an auxiliary message to the main message given by the
\fB\-message\fR 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.
.TP
\fB\-icon\fR \fIiconImage\fR
.
Specifies an icon to display. \fIIconImage\fR must be one of the
following: \fBerror\fR, \fBinfo\fR, \fBquestion\fR or
\fBwarning\fR. If this option is not specified, then the info icon will be
displayed.
