| white-on-black-color : (or/c (is-a?/c color%) string?) |
Registers a preference whose value will be updated when the user clicks on
one of the color scheme default settings in the preferences dialog.
Also calls preferences:set-default and
preferences:set-un/marshall with appropriate arguments to register
the preference.

This function registers a color preference and initializes the style list
returned from editor:get-standard-style-list. In particular, it
calls preferences:set-default and
preferences:set-un/marshall to install the pref for
pref-name, using color/sd as the default color. The
preference is bound to a style-delta%, and initially the
style-delta% changes the foreground color to color/sd,
unless color/sd is a style delta already, in which case it is just
used directly. Then, it calls
editor:set-standard-style-list-delta passing the
style-name and the current value of the preference
pref-name.
Finally, it adds calls preferences:add-callback to set a callback for pref-name that updates the style list when the preference changes.
If white-on-black-color is not #f, then the color of the color/sd argument is used in combination with white-on-black-color to register this preference with color-prefs:set-default/color-scheme.
If either background is
not #f, then it is used to construct the default background color
for the style delta.
Adds a preferences panel that configures the background color for
editor:basic-mixin.

Calls func with the subpanel of the preferences coloring panel
that corresponds to name.

| pref-sym : symbol? | ||||||||||||||||||||||||
| style-name : string? | ||||||||||||||||||||||||
| example-text : string? | ||||||||||||||||||||||||
| background? : boolean? = #f | ||||||||||||||||||||||||
Builds a panel with a number of controls for configuring a font: its color
(including a background configuration if background is #t)
and check boxes for bold, italic, and underline. The parent
argument specifies where the panel will be placed. The pref-sym
should be a preference (suitable for use with preferences:get and
preferences:set). The style-name specifies the name of a
style in the style list returned from
editor:get-standard-style-list and example-text is shown
in the panel so users can see the results of their configuration.
| (color-prefs:marshall-style-delta style-delta) → printable/c |
| style-delta : (is-a?/c style-delta%) |
Builds a printed representation for a style-delta.
| (color-prefs:unmarshall-style-delta marshalled-style-delta) |
| → (or/c false/c (is-a?/c style-delta%)) |
| marshalled-style-delta : printable/c |
Builds a style delta from its printed representation. Returns #f
if the printed form cannot be parsed.
