20 The tk_setPalette procedure changes the color scheme for Tk. It does
21 this by modifying the colors of existing widgets and by changing the
22 option database so that future widgets will use the new color scheme.
23 If tk_setPalette is invoked with a single argument, the argument is the
24 name of a color to use as the normal background color; tk_setPalette
25 will compute a complete color palette from this background color.
26 Alternatively, the arguments to tk_setPalette may consist of any number
27 of name-value pairs, where the first argument of the pair is the name
28 of an option in the Tk option database and the second argument is the
29 new value to use for that option. The following database names are
30 currently supported: activeBackground foregroundselect‐
31 Color activeForeground highlightBackgroundselectBack‐
32 ground background highlightColor selectForeground disabledFore‐
33 ground insertBackgroundtroughColor tk_setPalette tries to
34 compute reasonable defaults for any options that you do not specify.
35 You can specify options other than the above ones and Tk will change
36 those options on widgets as well. This feature may be useful if you
37 are using custom widgets with additional color options.
38 Once it has computed the new value to use for each of the color
40 options, tk_setPalette scans the widget hierarchy to modify the options
41 of all existing widgets. For each widget, it checks to see if any of
42 the above options is defined for the widget. If so, and if the
43 option's current value is the default, then the value is changed; if
44 the option has a value other than the default, tk_setPalette will not
45 change it. The default for an option is the one provided by the widget
46 ([lindex [$w configure $option] 3]) unless tk_setPalette has been run
47 previously, in which case it is the value specified in the previous
48 invocation of tk_setPalette.
49 After modifying all the widgets in the application, tk_setPalette adds
51 options to the option database to change the defaults for widgets cre‐
52 ated in the future. The new options are added at priority widgetDe‐
53 fault, so they will be overridden by options from the .Xdefaults file
54 or options specified on the command-line that creates a widget.
55 The procedure tk_bisque is provided for backward compatibility: it
57 restores the application's colors to the light brown (“bisque”) color
58 scheme used in Tk 3.6 and earlier versions.
