GETCOLOR (W*S)

Module

USE IFQWIN

result = GETCOLOR( )

Results

The result type is INTEGER(2). The result is the current color index, if successful; otherwise, -1.

GETCOLOR returns the current color index used for graphics over the background color as set with SETCOLOR. The background color index is set with SETBKCOLOR and returned with GETBKCOLOR. The color index of text over the background color is set with SETTEXTCOLOR and returned with GETTEXTCOLOR. These non-RGB color functions use color indexes, not true color values, and limit the user to colors in the palette, at most 256. For access to all system colors, use SETCOLORRGB, SETBKCOLORRGB, and SETTEXTCOLORRGB.

Example

!  Program to demonstrate GETCOLOR
 PROGRAM COLORS
 USE IFQWIN
 INTEGER(2) loop, loop1, status, color
 LOGICAL(4) winstat
 REAL rnd1, rnd2, xnum, ynum
 type (windowconfig) wc
 status = SETCOLOR(INT2(0))
!  Color random pixels with 15 different colors
 DO loop1 = 1, 15
   color = INT2(MOD(GETCOLOR() +1, 16))
   status = SETCOLOR (color) ! Set to next color
   DO loop = 1, 75
!  Set color of random spot, normalized to be on screen
     CALL RANDOM(rnd1)
     CALL RANDOM(rnd2)
     winstat = GETWINDOWCONFIG(wc)
     xnum = wc%numxpixels
