Hi,
I'm using FPC 2.4.3
Why is the following operator overload not allowed? Sometimes
TfpgColor can be a RRGGBB value (eg: clRed), and sometimes it is an
index to a color palette (eg: clWindowBackground). So I want to do
comparisons between two such colors.
The compiler error I get:
..../programming/fpgui/src/corelib/fpg_main.pas(414,58) Error:
Impossible operator overload
The types are defined as follows:
type
TfpgColor = type longword;
TFPColor = record
Red: word;
Green: word;
Blue: word;
Alpha: word;
end;
... now the unit with the compiler error ...
interface section:
operator = (const AColor1, AColor2: TfpgColor) b: Boolean;
implementation section:
operator = (const AColor1, AColor2: TfpgColor) b: Boolean;
var
c1, c2: TFPColor;
begin
c1 := fpgColorToFPColor(AColor1);
c2 := fpgColorToFPColor(AColor2);
b := (c1.Red = c2.Red) and (c1.Green = c2.Green) and
(c1.Blue = c2.Blue) and (c1.Alpha = c2.Alpha);
end;
