'\" 
'\" 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.

tk_optionMenu \- 建立菜单按钮和它的菜单
.SH "总览 SYNOPSIS"
\fBtk_optionMenu \fIw varName value \fR?\fIvalue value ...\fR?
.BE

.SH "描述 DESCRIPTION"
.PP
这个过程建立叫做 \fIw \fR的一个选项菜单按钮，并加上一个相关联的菜单。它们在一起允许用户选择用 \fIvalue\fR 参数给出的值中的一个。当前值被存储在用 \fIvarName\fR 给出名字的全局变量中，并且还将被显示为选项菜单按钮中的标签。用户可以点击菜单按钮来显示一个包括所有 \fIvalue \fR的菜单并接着选择一个新值。一旦选择了一个新值，则把它存储在这个变量中并在选项菜单按钮中出现。还可以通过设置这个变量来改变当前值。
.PP
从 \fBtk_optionMenu\fR 返回的值是与 \fIw \fR相关联的菜单的名字，这样调用者可以改变它的配置选项或以其他方式操纵它。
