运行时使用Dev的ImageListEditor

uses
  cxImageListEditor, cxGridMenuOperations;

{$R *.dfm}

procedure TForm1.Btn1Click(Sender: TObject);
var
  AEditor : TcxImageListEditor;
begin
  AEditor := TcxImageListEditor.Create;
  AEditor.Edit(TcxImageList(cxGridPopupMenuImages));
  AEditor.ExportImages('M:	est.bmp');
end;
