'\" 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
bindtags \- 确定对一个窗口提供那些绑定和求值的次序
.SH 总览 SYNOPSIS
\fBbindtags \fIwindow \fR?\fItagList\fR?
.BE

.SH 描述 DESCRIPTION
.PP
用  \fBbind\fR 命令建立的一个绑定，可以关联上一个特定的窗口如 \fB.a.b.c\fR，一个类的名字如  \fBButton\fR，关键字 \fBall\fR，或任何其他字符串。所有这些形式叫做绑定标签(\fIbinding tags\fR)。每个窗口包含绑定标签的一个列表，它决定这个窗口如何处理事件。当在一个窗口中发生一个事件，依次把它提供给这个窗口的每个标签: 对于每个标签，执行匹配给定标签和事件的最明确的绑定。匹配处理的详情请参见 \fBbind\fR。
.PP
缺省的，每个窗口有四个绑定标签，它们依次是这个窗口的名字，这个窗口的类的名字，这个窗口的最近的顶层祖先的名字，和 \fBall\fR。顶层窗口缺省的只有三个标签，因为顶层名字与这个窗口的名字相同。\fBbindtags\fR 命令允许读取和修改一个窗口的绑定标签。
.PP
如果只用一个参数调用 \fBbindtags\fR，则把 \fIwindow\fR 的当前绑定标签的集合作为一个列表返回。如果对 \fBbindtags\fR 指定了 \fItagList\fR 参数，则它必须是一个正确的列表；把 \fIwindow\fR 的标签变更为这个列表的元素。\fItagList\fR 的元素可以是任意的字符串；但是，任何以一个点号开始的标签将被作为一个窗口的名字对待 ；如果在处理一个事件的时候不存在叫这个名字的窗口，则忽略这个事件的这个标签。\fItagList\fR 中元素的次序决定执行绑定脚本来响应事件的次序。例如，命令
.CS
\fBbindtags .b {all . Button .b}\fR
.CE
对叫做 \fB.b\fR 的一个按钮颠倒求值绑定脚本的次序，首先调用 \fBall\fR 绑定，接着是 \fB.b\fR 的顶层(“.”)的绑定，随后是类绑定，最后是 \fB.b\fR 的绑定。如果 \fItagList\fR 是一个空列表则把 \fIwindow\fR 的绑定标签返回为上面描述的缺省状态。
.PP
可以使用 \fBbindtags\fRs 命令来为一个窗口介入任意的补充绑定标签，或则删除标准标签。例如，命令
.CS
\fBbindtags .b {.b TrickyButton . all}\fR
.CE
把 \fB.b\fR 的 \fBButton\fR 标签替换为 \fBTrickyButton\fR。这意味着与 \fBButton\fR 标签相关联的按钮的缺省组件绑定，将不在提供给 \fB.b\fR，转而提供与 \fBTrickyButton\fR (可能有一些新的按钮行为)关联的任何绑定。
