Delphi 5:如何暂停锚布局？

Question

有没有办法暂停表单上的所有锚定控件暂时移动或调整大小？即:

procedure ScaleFormBy(AForm: TForm; n, d: Integer);
begin
    AForm.SuspendAnchors();
    try
       AForm.ScaleBy(n, d);
    finally
       AForm.ResumeAnchors();
    end;
end;

我需要这样做,因为我正在打电话

AForm.ScaleBy(m, d);

哪个不能正确处理锚定控件.(它将左侧+右侧或顶部+底部锚定控件推离窗体边缘.

注意:我想禁用Anchors,而不是Alignment.

SuspendAnchors听起来像一个基本方法,但我不认为它是基础Delphi语言的一部分:)这里有一些代码可以解决这个问题:

var aAnchorStorage: Array of TAnchors;
procedure AnchorsDisable(AForm: TForm);
var
  iCounter: integer;
begin
  SetLength(aAnchorStorage, AForm.ControlCount);
  for iCounter := 0 to AForm.ControlCount - 1 do begin
    aAnchorStorage[iCounter] := AForm.Controls[iCounter].Anchors;
    AForm.Controls[iCounter].Anchors := [];
  end;
end;

procedure AnchorsEnable(AForm: TForm);
var
  iCounter: integer;
begin
  SetLength(aAnchorStorage, AForm.ControlCount);
  for iCounter := 0 to AForm.ControlCount - 1 do
    AForm.Controls[iCounter].Anchors := aAnchorStorage[iCounter];
end;

procedure TForm1.btnAnchorsDisableClick(Sender: TObject);
begin
  AnchorsDisable(Self);
end;

procedure TForm1.btnAnchorsEnableClick(Sender: TObject);
begin
  AnchorsEnable(Self);
end;
