To get the RGB index of a color use the function %MakeRGB.
The value of the parameter row
(col) can be also 0. So there is set
(detected) the color for defined row (column). If both row = 0
and col = 0, then the
color is set (detected) for the whole displayer.
Example
; setting the text color for the whole displayer
%HI_SetBrowserForeColor(_browser, 0, 0, _RGB)
; setting the text color for the column nr. 3
%HI_SetBrowserForeColor(_browser, 0, 3, _RGB)
; setting the text color for the item [2,3]
%HI_SetBrowserForeColor(_browser, 2, 3, _RGB)
