'\" 
'\" 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.

tk_setPalette, tk_bisque \- 修改 Tk 颜色调色板

.SH "描述 DESCRIPTION"
.PP
\fBtk_setPalette\fR 过程改变 Tk 的颜色方案。它通过修改现存组件的颜色和修改选项数据库来做这个工作，这样将来的组件将使用新颜色方案。如果用一个单一参数调用 \fBtk_setPalette\fR，则这个参数是用做普通背景色的一个颜色的名字；\fBtk_setPalette\fR 将从这个背景色计算出一个完整的颜色调色板。作为另一个选择，给 \fBtk_setPalette\fR 的参数可以由任意数目的名字-值对组成，对中的第一个参数是在 Tk 选项数据库中的一个选项的名字，而第二个参数是用于这个选项的新值。当前数据库支持下列名字:
.DS L
.ta 4c 8c
\fBactiveBackground	foreground	selectColor
activeForeground	highlightBackground	selectBackground
background	highlightColor	selectForeground
disabledForeground	insertBackground	troughColor\fR
.DE
\fBtk_setPalette\fR 尝试为你没有指定的所有选项计算合理的缺省。你可以指定上述之外的选项而 Tk 同样在组件上的这些选项。这个特征对使用了额外的颜色选项的定制组件可能有用。
.PP
一旦为每个颜色选项计算了新值，\fBtk_setPalette\fR 检索组件层次来修改所有现存组件的选项。对于每个组件，它检查这个组件是否定义了上述选项。如果是这样，并且如果这个选项的当前值是缺省的，则改变这个值；如果这个选项有一个不是缺省的值，\fBtk_setPalette\fR 将不改变它。如果以前未运行 \fBtk_setPalette\fR，则缺省值由组件来选项提供(\fB[lindex [$w configure $option] 3]\fR)，否则它是在前面的 \fBtk_setPalette\fR 调用中指定的值。
.PP
在修改了在应用中的所有组件之后，\fBtk_setPalette\fR 向选项数据库增加选项来改变将来建立的组件的缺省值。增加的新选项在优先级 \fBwidgetDefault\fR 上，所以将被来自 .Xdefaults 文件的选项或在建立一个组件的命令行上指定的选项所屏弃。
.PP
为向后兼容而提供了 \fBtk_bisque\fR: 它把应用的颜色恢复为 Tk 3.6 和以前版本中的浅黄(“bisque”)色方案。
