AdvStringGrid 复选框、goRowSelect

var
  I: Integer;
begin
  for I := 1 to 48 do
  begin
    AdvStringGrid1.AddCheckBox(0, I, True, True);
    AdvStringGrid1.Cells[1,I] := '第二列' + I.ToString;
    AdvStringGrid1.Cells[2,I] := '第三列' + I.ToString;
  end;
end;

但是你会发现，checkbox再单元的左侧了，想居中 怎么办，经过研究发现了advstring自身的一处bug,复选框是写死在左侧的。

我修改下官方的源码，让其写死居中就可了。

procedure TForm5.Button3Click(Sender: TObject);
var
  I: Integer;
begin
  for I := 1 to 48 do
  begin
    AdvStringGrid1.ColWidths[0] := 50; //改变第一列的宽度。
    AdvStringGrid1.AddCheckBox(0, I, True, True);
    AdvStringGrid1.Cells[1,I] := '第二列' + I.ToString;
    AdvStringGrid1.Cells[2,I] := '第三列' + I.ToString;
  end;
end;
