Converting Inno Setup WizardForm.Color to RGB
If I try this:
[Setup]
AppName=MyApp
AppVerName=MyApp
DefaultDirName={pf}MyApp
DefaultGroupName=MyApp
OutputDir=.
[Code]
function ColorToRGBstring(Color: TColor): string;
var
R,G,B : Integer;
begin
R := Color and $ff;
G := (Color and $ff00) shr 8;
B := (Color and $ff0000) shr 16;
result := 'red:' + inttostr(r) + ' green:' + inttostr(g) + ' blue:' + inttostr(b);
end;
procedure InitializeWizard();
begin
MsgBox(ColorToRGBstring(WizardForm.Color),mbConfirmation, MB_OK);
end;
I get: red:15 green:0 blue:0
But the result should be: 240 240 240 (grey)
What is wrong?
I need to get the proper TColor and convert it to RGB color code.
When the first byte is $FF , the last byte is an index in a system color palette.
You can get RGB of the system color using GetSysColor function.
function GetSysColor(nIndex: Integer): DWORD;
external 'GetSysColor@User32.dll stdcall';
function ColorToRGB(Color: TColor): Cardinal;
begin
if Color < 0 then
Result := GetSysColor(Color and $000000FF) else
Result := Color;
end;
The ColorToRGB code is copied from Delphi VCL (Vcl.Graphics unit).
