'\" 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_dialog \- 建立模式对话框并等待响应
.SH "总览 SYNOPSIS"
\fBtk_dialog \fIwindow title text bitmap default string string ...\fR
.BE

.SH "描述 DESCRIPTION"
.PP
这个过程是 Tk 脚本库的一部分。它的参数描述一个对话框:
.TP
\fIwindow\fR
用于对话框的顶层窗口的名字。销毁叫这个名字的任何现存窗口。
.TP
\fItitle\fR
显示在窗口管理器给这个对话框的标题栏中的文字。
.TP
\fItext\fR
出现在对话框顶部的消息。
.TP
\fIbitmap\fR
如果非空，则指定在对话框的顶部显示在文字左边的一个位图。如果它是一个空串则在对话框中不显示位图。
.TP
\fIdefault\fR
如果它是大于等于零的一个整数，则它给出成为这个对话框的缺省按钮的按钮的索引(0 给最左的按钮，并以次类推)。如果小于零或是一个空串则没有缺省按钮。
.TP
\fIstring\fR
为这些参数中的每个建立一个按钮。按从左至右的次序，每个\fIstring\fR 指定要在一个按钮中显示的文字。
.PP
在建立了对话框之后，\fBtk_dialog\fR 等待用户选择按钮中的一个，要么通过用鼠标点击按钮之一要么通用键入返回键来调用缺省按钮(如果有的话)。接着它返回选择的按钮的索引: 0 是最左的按钮，1 是下一个按钮，并以次类推。如果这个对话框的窗口在用户选择按钮中的一个之前就被销毁了，则返回 -1。
.PP
在等待用户响应期间，\fBtk_dialog\fR 设置一个本地夺取(grab)。这将防止用户以除了调用这个对话框之外的任何方式与应用进行交互。
