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
