'\" 
'\" 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 "描述 DESCRIPTION"
.PP
\fBtkwait\fR 
命令等待多个事情中的一个发生，接着返回而不做其他动作。返回的值总是一个空串。如果第一个参数是 \fBvariable\fR (或它的任何简写)则第二个参数是一个全局变量的名字，并且命令等待这个变量被修改。如果第一个参数是\fBvisibility\fR (或它的任何简写)则第二个参数是一个窗口的名字，并且 \fBtkwait\fR 命令等待它的可见性状态的变化(由到来的 VisibilityNotify 事件来指示)。这种形式典型的用于等待一个新近建立的窗口在屏幕上显示，此后做一些动作。如果第一个参数是 \fBwindow\fR (或它的任何简写)则它的第二个参数是一个窗口的名字，并且 \fBtkwait\fR 命令等待这个窗口被销毁。这种形式典型的用于等待用户完成与与对话框的交互，此后使用这次交互的结果。
.PP
在 \fBtkwait\fR 命令等待期间它以平常的方式处理事件，所以应用可以继续响应用户交互。如果一个事件处理器再次调用 \fBtkwait\fR，在外部调用可以完成之前嵌套的调用必须完成。
