The Color Selector widget
SYNOPSIS
#include <Xm/ColorS.h>
DESCRIPTION
The Color Selector widget allows users to choose a color by using
either a set of RGB sliders or choosing from a list of all colors
available in the rgb database. The name or rgb value, as well as the
color selected, are dynamically displayed to the user as they pick and
choose different colors.

blueSliderLabel
The string appearing for the label of the blue slider
colorListTogLabel
The string appearing for the label of the color list toggle
colorMode
The color list can be used in either slider or list mode. Acceptable
values are XmListMode and XmScaleMode. This resource allows the appli‐
cation to determine the mode that the color selector should use when it
is created. After this point, the user may freely change modes by uti‐
lizing a pair of radio buttons in the color selector. A type converter
is registered to convert the strings "ScaleMode" and "ListMode" to
color modes for use with the resource database.
colorName
This resource controls the color name that is currently displayed to
the user. This value can be modified to change the color displayed in
the color selector or queried to find the color the user has selected.
The string returned here is either a color name or a pound sign (#)
followed by a set of rgb values as specified in the Xlib specification.

The message which is displayed when the Color Selector cannot read the
rgb.txt file. The message is displayed at the top of the window in
which the color list would normally appear.

color field when the Color Selector cannot allocate a read/write color
cell

Widget parent, /* Widget id of parent for ColorSelector */
String name, /* Name of the created widget */
ArgList args, /* argument list */

Children
The color selector is composed of many sub-widgets. As with all wid‐
gets, most values are passed to this widget through the argument list
at creation time or via set values and are passed to each of this wid‐
get's children, although get values requests must be made on a child-
by-child basis. The children of the color selector are listed below.
The documentation for each of the children should be consulted for a
list of resources for each child.
