'\" 
'\" The definitions below are for supplemental macros used in Tcl/Tk
'\" manual entries.
'\"
'\" .AP type name in/out ?indent?
'\"	Start paragraph describing an argument to a library procedure.
'\"	type is type of argument (int, etc.), in/out is either "in", "out",
'\"	or "in/out" to describe whether procedure reads or modifies arg,
'\"	and indent is equivalent to second arg of .IP (shouldn't ever be
'\"	needed;  use .AS below instead)
'\"
'\" .AS ?type? ?name?
'\"	Give maximum sizes of arguments for setting tab stops.  Type and
'\"	name are examples of largest possible arguments that will be passed
'\"	to .AP later.  If args are omitted, default tab stops are used.
'\"
'\" .BS
'\"	Start box enclosure.  From here until next .BE, everything will be
'\"	enclosed in one large box.
'\"
'\" .BE
'\"	End of box enclosure.
'\"
'\" .CS
'\"	Begin code excerpt.
'\"
'\" .CE
'\"	End code excerpt.
'\"
'\" .VS ?version? ?br?
'\"	Begin vertical sidebar, for use in marking newly-changed parts
'\"	of man pages.  The first argument is ignored and used for recording
'\"	the version when the .VS was added, so that the sidebars can be
'\"	found and removed when they reach a certain age.  If another argument
'\"	is present, then a line break is forced before starting the sidebar.
'\"
'\" .VE
'\"	End of vertical sidebar.
'\"
'\" .DS
'\"	Begin an indented unfilled display.
'\"
'\" .DE
'\"	End of indented unfilled display.
'\"
'\" .SO
'\"	Start of list of standard options for a Tk widget.  The
'\"	options follow on successive lines, in four columns separated
'\"	by tabs.
'\"
'\" .SE
'\"	End of list of standard options for a Tk widget.
'\"
'\" .OP cmdName dbName dbClass
'\"	Start of description of a specific option.  cmdName gives the
'\"	option's name as specified in the class command, dbName gives
'\"	the option's name in the option database, and dbClass gives
'\"	the option's class in the option database.
'\"
'\" .UL arg1 arg2
'\"	Print arg1 underlined, then print arg2 normally.

.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.

The following option-value pairs are supported:
.TP
\fB\-default\fR \fIname\fR
\fIName\fR gives the symbolic name of the default button for
this message window ('ok', '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\-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.
.TP
\fB\-message\fR \fIstring\fR
Specifies the message to display in this message box.
.TP
\fB\-parent\fR \fIwindow\fR
Makes \fIwindow\fR the logical parent of the message box. The message
box is displayed on top of its parent window.
.TP
\fB\-title\fR \fItitleString\fR
Specifies a string to display as the title of the message box. The
default value is an empty string.
.TP
\fB\-type\fR \fIpredefinedType\fR
Arranges for a predefined set of buttons to be displayed. The
following values are possible for \fIpredefinedType\fR:
.RS
.TP 18
\fBabortretryignore\fR
Displays three buttons whose symbolic names are \fBabort\fR,
\fBretry\fR and \fBignore\fR.
.TP 18
\fBok\fR
Displays one button whose symbolic name is \fBok\fR.
.TP 18
\fBokcancel\fR
Displays two buttons whose symbolic names are \fBok\fR and \fBcancel\fR.
.TP 18
\fBretrycancel\fR
Displays two buttons whose symbolic names are \fBretry\fR and \fBcancel\fR.
.TP 18
\fByesno\fR
Displays two buttons whose symbolic names are \fByes\fR and \fBno\fR.
.TP 18
\fByesnocancel\fR
Displays three buttons whose symbolic names are \fByes\fR, \fBno\fR
and \fBcancel\fR.
