'\" 
'\" 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 \- 操縱 Tk 內部狀態
.SH "總覽 SYNOPSIS"
\fBtk\fR \fIoption \fR?\fIarg arg ...\fR?
.BE

.SH "描述 DESCRIPTION"
.PP
\fBtk\fR 命令提供對 Tk 內部狀態的雜類元素的訪問。這個命令操縱的多數信息適合於作爲一個整體的應用(程序)，或者是一個屏幕或顯示器，而不是一個特定的窗口。依賴於 \fIoption\fR 參數，這個命令可以接受的多種不同的的形式。合法的形式有:
.TP
\fBtk appname \fR?\fInewName\fR?
如果未指定 \fInewName\fR，則這個命令返回這個應用(程序)的名字(這個名字可以用在 \fBsend\fR 命令中來與應用通信)。如果指定了 \fInewName\fR，則把應用的名字變更爲 \fInewName\fR。如果給定名字已經使用了，則添加“\fB#2\fR”或“\fB#3\fR”形式的後綴來保持名字的唯一性。這個命令的結果是實際上選擇的名字。\fInewName\fR 不應該開始於大寫字符。這將妨礙選項處理，因爲以大寫開頭的名字被假定爲類；結果是 Tk 可能找不到給應用的一些選項。如果通過刪除 \fBsend\fR 而停用了發送，這個命令將重新啓用它們並建立 \fBsend\fR 命令。
.TP
\fBtk scaling \fR?\fB\-displayof \fIwindow\fR? ?\fInumber\fR?
.
設置和查詢 Tk 使用的當前的比例(縮放)因子，它用於在物理單位(如點、英寸、或毫米)和象素之間進行轉換。\fInumber\fR 參數是指定在 \fIwindow \fR的顯示器上每點的象素數的一個浮點數。如果省略了 \fIwindow\fR 參數，則它缺省爲主窗口。如果省略了 \fInumber\fR 參數，則返回比例因子的當前值。
.RS
.PP
“點” (``point'') 是等於 1/72 英寸的一個度量單位。比例因子 1.0 對應於每點 1 象素，這等價與一個 72 dpi 的監視器。比例因子 1.25 意味着每點 1.25 個象素，這是 90 dpi 監視器的設置；在一個 72 dpi 監視器上設置比例因子爲 1.25 將導致在應用中顯示的所有東西是正常的 1.25 倍。在應用啓動的時候，基於安裝的監視器的特性類設置比例因子的初始值，但可以在任何時候變更。使用變更了的比例因子的度量將使用新的比例因子，但對現存的組件是否動態的調整自身大小來適應新的比例因子未做規定。
.RE
.VS 8.3
.TP
\fBtk useinputmethods \fR?\fB\-displayof \fIwindow\fR? ?\fIboolean\fR?
.
設置和查詢 Tk 是否應當使用 XIM (X 輸入方法：X Input Methods)來過濾事件的狀態。在一些地域(如: 日本、高麗)中使用 XIM 來處理特殊的輸入設備。這個特徵只在 X 上重要。如果不能獲得 XIM 支持，它總是返回 0。如果省略了 \fIwindow\fR 參數，則缺省爲主窗口。如果省略了 \fIboolean\fR 參數，則返回當前狀態。
