防止RTL TListView镜像复选框和/或图形

我试图使ListView的列从右向左显示。这一点已经得到了证实。但问题在于图标和复选框。当我使用

SetWindowLong

制作ListView RTL时，它也会镜像图形和复选框，这是不需要的。我可以使用编辑工具镜像图形，虽然麻烦但可行，但我不知道如何处理复选框

我想他们都有相同的原因，所以我搜索了一下，在中找到了一整篇关于RTL布局的文章。在第节中，它指出了图形问题。建议使用

layout\u RTL

和

layout\u BITMAPORIENTATIONPRESERVED

标志更改DC的布局样式

这是我通过结合文章中建议的方法和上面提到的答案实现的功能：

const
  LAYOUT_RTL = 1;
  LAYOUT_BITMAPORIENTATIONPRESERVED = 8;

function GetLayout(DC: HDC): DWORD; stdcall; external 'gdi32.dll';
function SetLayout(DC: HDC; dwLayout: DWORD): DWORD; stdcall; external 'gdi32.dll';

procedure MakeRTL(const Handle: HWND);
var
  DC: HDC;
begin
  SetWindowLong(Handle, GWL_EXSTYLE,
    GetWindowLong(Handle, GWL_EXSTYLE) or WS_EX_LAYOUTRTL);

  DC := GetWindowDC(Handle);
  if DC <> 0 then
    SetLayout(DC, GetLayout(DC) or LAYOUT_RTL or LAYOUT_ORIENTATIONMASK);

  InvalidateRect(Handle, nil, True);
end;

const
布局_RTL=1；
布局\位图方向保留=8；
功能GetLayout（DC:HDC）：DWORD；stdcall；外部“gdi32.dll”；
函数集布局（DC:HDC；dwLayout:DWORD）：DWORD；stdcall；外部“gdi32.dll”；
程序MakeRTL（const句柄：HWND）；
变量
DC:HDC；
开始
SetWindowLong（手柄，GWL_EXSTYLE，
GetWindowLong（句柄、GWL_EXSTYLE）或WS_EX_LayoutTL）；
DC:=GetWindowDC（句柄）；
如果DC为0，则
设置布局（DC、GetLayout（DC）或布局RTL或布局方向任务）；
无效（句柄，无，真）；
结束；

但这并没有改变任何事情。我试着阻止它们中的任何一个，改变它们的顺序，改变不同的地方来称呼它，但没有成功

现在的问题是，如何使ListView的列从右向左显示，而不镜像图形或复选框

我正在使用Win10 x64和Delphi 2010

如果您想重现问题，以下是我的delphi代码：

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, ComCtrls, ImgList, StdCtrls, CommCtrl, ShellAPI;

type
  TForm1 = class(TForm)
    ListView1: TListView;
    ImageList1: TImageList;
    ListView2: TListView;
    Button1: TButton;
    Label1: TLabel;
    procedure FormActivate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
    procedure Label1Click(Sender: TObject);
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

const
  LAYOUT_RTL = 1;
  LAYOUT_BTT = 2;
  LAYOUT_VBH = 4;
  LAYOUT_ORIENTATIONMASK = LAYOUT_RTL or LAYOUT_BTT or LAYOUT_VBH;
  LAYOUT_BITMAPORIENTATIONPRESERVED = 8;

function GetLayout(DC: HDC): DWORD; stdcall; external 'gdi32.dll';
function SetLayout(DC: HDC; dwLayout: DWORD): DWORD; stdcall; external 'gdi32.dll';

procedure MakeRTL(const Handle: HWND);
var
  DC: HDC;
begin
  SetWindowLong(Handle, GWL_EXSTYLE,
    GetWindowLong(Handle, GWL_EXSTYLE) or WS_EX_LAYOUTRTL);

  DC := GetWindowDC(Handle);
  if DC <> 0 then
    SetLayout(DC, GetLayout(DC) or LAYOUT_RTL or LAYOUT_ORIENTATIONMASK);

  InvalidateRect(Handle, nil, True);
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  MakeRTL(ListView_GetHeader(ListView1.Handle));
  MakeRTL(ListView1.Handle);
end;

procedure TForm1.FormActivate(Sender: TObject);
var
  I: Integer;
begin
  for I := 0 to ListView1.Items.Count - 1 do
  begin
    ListView1.Items[I].Checked := True;
    ListView2.Items[I].Checked := True;
  end;
end;

procedure TForm1.Label1Click(Sender: TObject);
begin
  ShellExecute(0, 'open', 'https://icons8.com/icons/set/check', '', '', SW_SHOWNORMAL);
end;

end.
