XmSetColorCalculation(library call)									       XmSetColorCalculation(library call)

NAME

       XmSetColorCalculation -- A function to set the procedure used for default color calculation

SYNOPSIS

       #include <Xm/Xm.h>
       XmColorProc XmSetColorCalculation(
       XmColorProc color_proc);

DESCRIPTION

       XmSetColorCalculation sets the procedure to calculate default colors.  This procedure is used to calculate the foreground, top shadow, bot-
       tom shadow, and select colors on the basis of a given background color.	If called with an argument of NULL, it restores the default proce-
       dure used to calculate colors.

       color_proc
		 Specifies the procedure to use for color calculation.

       Following is a description of the XmColorProc type used by XmSetColorCalculation:

       void (*color_proc) (background_color, foreground_color, select_color, top_shadow_color,
       bottom_shadow_color)
	       XColor  *background_color;
	       XColor  *foreground_color;
	       XColor  *select_color;
	       XColor  *top_shadow_color;
	       XColor  *bottom_shadow_color;
       (void)

       Specifies  the procedure used to calculate default colors.  The procedure is passed a pointer to an XColor structure representing the back-
       ground color.  The pixel, red, green, and blue members of this structure are filled in with values that are valid for the current colormap.

       The procedure is passed pointers to XColor structures representing the foreground, select, top shadow, and bottom shadow colors to be  cal-
       culated.   The  procedure  calculates and fills in the red, green, and blue members of these structures.  The procedure should not allocate
       color cells for any of these colors.

       background_color
		 Specifies the background color.

       foreground_color
		 Specifies the foreground color to be calculated.

       select_color
		 Specifies the select color to be calculated.

       top_shadow_color
		 Specifies the top shadow color to be calculated.

       bottom_shadow_color
		 Specifies the bottom shadow color to be calculated.

RETURN

       Returns the color calculation procedure that was used at the time this routine was called.
