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, bottom
shadow, and select colors on the basis of a given background color. If
called with an argument of NULL, it restores the default procedure used
to calculate colors.
color_proc
Specifies the procedure to use for color calculation.
Following is a description of the XmColorProc type used by XmSetColor-
Calculation:
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 proce-
dure is passed a pointer to an XColor structure representing the back-
ground color. The pixel, red, green, and blue members of this struc-
ture 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 calcu-
lated. 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
