NAME

       XmGetColors -- A function that generates foreground, select, and shadow colors

SYNOPSIS

       #include <Xm/Xm.h>
       void XmGetColors(
       Screen * screen,
       Colormap colormap,
       Pixel background,
       Pixel * foreground,
       Pixel * top_shadow,
       Pixel * bottom_shadow,
       Pixel * select);

DESCRIPTION

       XmGetColors takes a screen, a colormap, and a background pixel, and returns pixel values for foreground, select, and shadow colors.

       screen	 Specifies the screen for which these colors should be allocated.

       colormap  Specifies the colormap from which these colors should be allocated.

       background
		 Specifies the background on which the colors should be based.

       foreground
		 Specifies a pointer to the returned foreground pixel value.  If this argument is NULL, no value is allocated or returned for this
		 color.

       top_shadow
		 Specifies a pointer to the returned top shadow pixel value.  If this argument is NULL, no value is allocated or returned for this
		 color.

       bottom_shadow
		 Specifies  a  pointer to the returned bottom shadow pixel value.  If this argument is NULL, no value is allocated or returned for
		 this color.

       select	 Specifies a pointer to the returned select pixel value.  If this argument is NULL, no value is allocated  or  returned  for  this
		 color.

NAME

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

SYNOPSIS

       #include <Xm/Xm.h>

       XmColorProc XmSetColorCalculation (color_proc)
	       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.  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;

       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.  Specifies the background color.  Specifies the foreground color  to  be  calculated.   Specifies  the
       select color to be calculated.  Specifies the top shadow color to be calculated.  Specifies the bottom shadow color to be calculated.

RETURN VALUE

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