'\" 
'\" 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
tkvars \- Tk 使用或設定的變數
.BE

.SH "描述 DESCRIPTION"
.PP
在 Tk 的執行的各個時期設定或使用下列 Tcl 變數:
.TP 15
\fBtk_library\fR
這個變數持有一個目錄的檔名字，它包含與 Tk 有關的一個 Tcl 指令碼庫。這些指令碼包含通常在 Tk 應用啟動的時候處理的一個初始化檔案，加上包含實現元件預設行為的過程的其他檔案。在向一個解釋其新增 Tk 的時候設定 \fBtcl_library\fR 的初始值；這是透過查詢許多不同的目錄直到找到包含一個適當的 Tk 啟動指令碼來完成的。如果存在 \fBTK_LIBRARY\fR 環境變數，則首先查詢它指名的目錄。如果未設定 \fBTK_LIBRARY\fR 或者未引用一個適當的目錄，則基於系列位置檢查其他一些目錄，編輯進去(compiled-in)的預設位置，Tcl  庫目錄的位置，包含應用的二進位制檔案的位置，和當前工作目錄。應用可以修改這個變數來切換到一個不同的庫上。
.TP
\fBtk_patchLevel\fR
包含給出 Tk 的當前補丁級別的一個十進位制整數。補丁級別在每次新發行或修補時增加，並唯一的標識一個 Tk 的官方版本。
.TP
\fBtkPriv\fR
這個變數是一個數組，它包含 Tk 私有的許多資訊。Tk 庫過程和預設繫結使用 \fBtkPriv\fR 的元素。Tk 以外的任何程式碼都不應該訪問它。
.TP
\fBtk_strictMotif\fR
預設的把這個變數設定為零。如果一個應用把它設定為一，則 Tk 嘗試保持儘可能的與 Motif 觀感標準相接近。例如，活躍元素如按鈕和捲軸滑塊在指標經過它們的時候不改變顏色。
.TP 15
\fBtk_version\fR
Tk 為每個應用在直譯器中設定這個變數。這個變數持有 Tk 庫的 \fImajor\fR.\fIminor\fR\fI \fR形式的當前版本號。 \fIMajor\fR 和 \fIminor\fR 是整數。在包含不反向相容的變更的 Tk 發行中增加主版本號(就是說，可能必須改變現存的 Tk 應用和指令碼來在新發行下工作的時候)。在每次 Tk 的新發行中增加次版本號，但在主版本號變更的時候被複位為零。
