NAME
tk_setPalette, tk_bisque - Modify the Tk color palette
SYNOPSIS
tk_setPalette background
tk_setPalette name value ?name value ...?
tk_bisque
_________________________________________________________________
DESCRIPTION
The tk_setPalette procedure changes the color scheme for Tk.
It does this by modifying the colors of existing widgets and
by changing the option database so that future widgets will
use the new color scheme. If tk_setPalette is invoked with
a single argument, the argument is the name of a color to
use as the normal background color; tk_setPalette will
compute a complete color palette from this background color.
Alternatively, the arguments to tk_setPalette may consist of
any number of name-value pairs, where the first argument of
the pair is the name of an option in the Tk option database
and the second argument is the new value to use for that
option. The following database names are currently
supported:
activeBackground foregroundselectColor
activeForeground highlightBackgroundselectBackground
background highlightColor selectForeground
disabledForeground insertBackgroundtroughColor
tk_setPalette tries to compute reasonable defaults for any
options that you don't specify. You can specify options
other than the above ones and Tk will change those options
on widgets as well. This feature may be useful if you are
using custom widgets with additional color options.
Once it has computed the new value to use for each of the
color options, tk_setPalette scans the widget hierarchy to
modify the options of all existing widgets. For each
widget, it checks to see if any of the above options is
defined for the widget. If so, and if the option's current
value is the default, then the value is changed; if the
option has a value other than the default, tk_setPalette
will not change it. The default for an option is the one
provided by the widget ([lindex [$w configure $option] 3])
unless tk_setPalette has been run previously, in which case
it is the value specified in the previous invocation of
tk_setPalette.

After modifying all the widgets in the application,
tk_setPalette adds options to the option database to change
the defaults for widgets created in the future. The new
options are added at priority widgetDefault, so they will be
overridden by options from the .Xdefaults file or options
specified on the command-line that creates a widget.
The procedure tk_bisque is provided for backward
compatibility: it restores the application's colors to the
light brown (``bisque'') color scheme used in Tk 3.6 and
earlier versions.
