  10 '\" The definitions below are for supplemental macros used in Tcl/Tk
  11 '\" manual entries.
  12 '\"
  13 '\" .AP type name in/out ?indent?
  14 '\"     Start paragraph describing an argument to a library procedure.
  15 '\"     type is type of argument (int, etc.), in/out is either "in", "out",
  16 '\"     or "in/out" to describe whether procedure reads or modifies arg,
  17 '\"     and indent is equivalent to second arg of .IP (shouldn't ever be
  18 '\"     needed;  use .AS below instead)
  19 '\"
  20 '\" .AS ?type? ?name?
  21 '\"     Give maximum sizes of arguments for setting tab stops.  Type and
  22 '\"     name are examples of largest possible arguments that will be passed
  23 '\"     to .AP later.  If args are omitted, default tab stops are used.
  24 '\"
  25 '\" .BS
  26 '\"     Start box enclosure.  From here until next .BE, everything will be
  27 '\"     enclosed in one large box.
  28 '\"
  29 '\" .BE
  30 '\"     End of box enclosure.
  31 '\"
  32 '\" .CS
  33 '\"     Begin code excerpt.
  34 '\"
  35 '\" .CE
  36 '\"     End code excerpt.
  37 '\"
  38 '\" .VS ?version? ?br?
  39 '\"     Begin vertical sidebar, for use in marking newly-changed parts
  40 '\"     of man pages.  The first argument is ignored and used for recording
  41 '\"     the version when the .VS was added, so that the sidebars can be
  42 '\"     found and removed when they reach a certain age.  If another argument
  43 '\"     is present, then a line break is forced before starting the sidebar.
  44 '\"
  45 '\" .VE
  46 '\"     End of vertical sidebar.
  47 '\"
  48 '\" .DS
  49 '\"     Begin an indented unfilled display.
  50 '\"
  51 '\" .DE
  52 '\"     End of indented unfilled display.
  53 '\"
  54 '\" .SO
  55 '\"     Start of list of standard options for a Tk widget.  The
  56 '\"     options follow on successive lines, in four columns separated
  57 '\"     by tabs.
  58 '\"
  59 '\" .SE
  60 '\"     End of list of standard options for a Tk widget.
  61 '\"
  62 '\" .OP cmdName dbName dbClass
  63 '\"     Start of description of a specific option.  cmdName gives the
  64 '\"     option's name as specified in the class command, dbName gives
  65 '\"     the option's name in the option database, and dbClass gives
  66 '\"     the option's class in the option database.
  67 '\"
  68 '\" .UL arg1 arg2
  69 '\"     Print arg1 underlined, then print arg2 normally.

 249 .SH NAME
 250 clipboard \- 操纵 Tk 剪贴板
 251 .SH "总览 SYNOPSIS"
 252 \fBclipboard \fIoption\fR ?\fIarg arg ...\fR?
 253 .BE
 254
 255 .SH "描述 DESCRIPTION"
 256 .PP
 257 这个命令提供了到 Tk 剪贴板的 Tcl 接口，它使用选择机制来为以后的取回存储数据。要把数据复制到剪贴板中，必须调用 \fBclipboard clear\fR，随后是到 \fBclipboard append \fR的一个或多个调用的一个序列。要确保自动更新剪贴板，在返回到事件循环之前必须完成所有添加。
 258 .PP
 259 给 \fBclipboard\fR 的第一个参数决定剩余参数的格式和这个命令的行为。当前支持下列形式(form):
 260 .PP
 261 .TP
 262 \fBclipboard clear\fR ?\fB-displayof\fR \fIwindow\fR?
 263 要求在 \fIwindow \fR的显示器上剪贴板的所有权并删除所有以前的内容。\fIWindow\fR 缺省为“.”。返回一个空串。
 264 .TP
 265 \fBclipboard append\fR ?\fB\-displayof\fR \fIwindow\fR? ?\fB\-format\fR \fIformat\fR? ?\fB\-type\fR \fItype\fR? ?\fB\-\|\-\fR? \fIdata\fR
 266 向在 \fIwindow \fR的显示器上的剪贴板添加 \fIdata\fR  ，其形式由 \fItype\fR 给出，表示法(representation)由 \fIformat\fR 给出，并且要求在 \fIwindow \fR的显示器上剪贴板的所有权。
 267 .RS
 268 .PP
 269 \fIType\fR 参数指定返回的选择的形式(用 ICCCM 术语是想要的转换“目标”)，并且应当是一个原子名字如     STRING 或 FILE_NAME；详情参见客户间通信协定手册。\fIType\fR 缺省为 STRING。
 270 .PP
 271 \fIformat\fR 参数指定用来把选择传输(transmit)到请求者的表示法(ICCCM 的表 2 的第二列)，并且缺省为 STRING。如果 \fIformat\fR 是 STRING，则把选择传输为 8-bit ASCII 字符。如果 \fIformat\fR 是 ATOM，则把 \fIdata\fR 分割为用白空格分隔的字段；把每个字段转换成它的原子值，传输 32-bit 原子值而不是原子的名字。对于任何其他的 \fIformat\fR，把  \fIdata\fR  分割为用白空格分隔的字段；把每个字段转换成一个 32-bit  整数；向选择的请求者传输一个整数的数组。注意在转换之前串联(concatenate)传递给  \fBclipboard append\fR  的字符串，所以调用者必须注意确保跨越字符串边界的间隔。添加到剪贴板的有相同 \fItype\fR&nbsp; 的所有项目必须有相同的 \fIformat\fR。
 272 .PP
 273 \fIformat\fR 参数只在与不使用 Tk 的请求者相兼容时需要。如果使用 Tk 工具箱来取回 CLIPBOARD 选择，则在请求端把这个值转换回一个字符串，所以 \fIformat\fR 是无关的(irrelevant)。
 274 .PP
 275 \fB\-\|\-\fR 参数来标记选项的结束: 下一个参数总是被用做 \fIdata\fR。在数据开始于 \fB-\fR 的时候这个特征会带来方便。
