高分求解关于调色板的问题(200分)

我想改变delphi的调色板控件的颜色索引表。想用一副位图的颜色表来改变它。但是TcolorGrid.FPaletteEntries
好像是只读的。请问有什么方法可以改变它吗？
我用的是如下方法：
for I:=0 to NumberColor-1 do
begin
with FPaletteEntries do
begin
peRed := ColorTab.rgbRed;//ColorTab是一幅位图的颜色表。ColorTab:Array of RGBQUAD
peGreen := ColorTab.rgbGreen;
peBlue := ColorTab.rgbBlue;
end;
end;
愿以200分相赠。

好像没有办法，FPaletteEntries是私有成员，
除非你修改TcolorGrid的源文件

从这个类继承，然后把这个属性用自己的代码重新写把DELPHI带的给覆盖掉。

等我回去查一下资料

implementation

{$R *.DFM}

procedure TForm1.FormCreate(Sender: TObject);
var
i: Word;
begin
Bmap := TBitmap.Create;
Bmap.LoadFromFile('Test.bmp');
Image1.Canvas.StretchDraw(Image1.BoundsRect, Bmap);
end;

procedure TForm1.QNewPalette(var Msg: TWMQueryNewPalette);
var
i: Word;
DC: HDC;
HPold: HPalette;
begin
DC := Form1.Canvas.Handle;
HPold := SelectPalette(DC, Bmap.Palette, False);
i := RealizePalette(DC);
SelectPalette(DC, HPold, False);
if (i > 0) then
InvalidateRect(Handle, Nil, False);
Msg.Result := i;
end;

procedure TForm1.PalChanged(var Msg: TWMPaletteChanged);
var
i: Word;
DC: HDC;
HPold: HPalette;
begin
if (Msg.PalChg = Handle) then
Msg.Result := 0
else
begin
DC := Form1.Canvas.Handle;
HPold := SelectPalette(DC, Bmap.Palette, True);
i := RealizePalette(DC);
UpdateColors(DC);
SelectPalette(DC, HPold, False);
end;
end;

procedure TForm1.FormClose(Sender: TObject; var Action: TCloseAction);
begin
Bmap.Free;
end;

end.

接受答案了.
