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 wid-get widget
get 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 config-ure configure
ure $option] 3]) unless tk_setPalette has been run previously, in which case it is the value speci-fied specified
fied 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 wid-getDefault, widgetDefault,
getDefault, 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.
