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.

All resource names begin with XmN and all resource class names begin with XmC.

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 application to determine  the mode that the color selector should use when it is created. After this point, the  user may freely change modes by utilizing 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.

fileReadError

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.

marginHeight

marginWidth

This is the amount of space left between each of the children in the color selector  and between the outside children and the edge of the color selector widget.

This is the name of the file to be loaded, which contains the valid color names.  Each of these names is sorted and the duplicates removed before being shown to  the user.

Convenience Routine

XmCreateColorSelector - Widget creation convenience routine

Widget XmCreateColorSelector( 
	Widget parent,     /* Widget id of parent for ColorSelector */
	String name,       /* Name of the created widget */
	ArgList args,      /* argument list */
	Cardinal num_args  /* number of items in argument list */
	)				 

Children

The color selector is composed of many sub-widgets. As with all widgets, 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 widget'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.
