Получить дескриптор текущего курсора

{ 
  The GetCursor() API is limited in that it does not, by default, return a handle to the current 
  cursor when that cursor is owned by another thread. This article demonstrates a way to retrieve 
  the current cursor regardless of what thread owns it. 
  For example, when you wish to include the image of the cursor in a screen capture. 
}


function GetCursorHandle: HCURSOR;
var
  hWindow: HWND;
  pt: TPoint;
  pIconInfo: TIconInfo;
  dwThreadID, dwCurrentThreadID: DWORD;
begin
  // Find out which window owns the cursor 
  // Das zum Mauszeiger zugehцrige Fenster finden 
  GetCursorPos(pt);
  hWindow := WindowFromPoint(pt);

  // Get the thread ID for the cursor owner. 
  // Thread ID des Fensters ermitteln 
  dwThreadID := GetWindowThreadProcessId(hWindow, nil);

  // Get the thread ID for the current thread 
  // Thread ID fьr den aktuellen Thread ermitteln 
  dwCurrentThreadID := GetCurrentThreadId;

  // If the cursor owner is not us then we must attach to 
  // the other thread in so that we can use GetCursor() to 
  // return the correct hCursor 

  // Wenn der Mauszeiger zu einem anderen Thread gehцrt, mьssen wir 
  // an den anderen Thread anhдngen. 

  if (dwCurrentThreadID <> dwThreadID) then
  begin
    if AttachThreadInput(dwCurrentThreadID, dwThreadID, True) then
    begin
      // Das Handle des Mauszeigers ermitteln 
      // Get the handle to the cursor 
      Result := GetCursor;
      AttachThreadInput(dwCurrentThreadID, dwThreadID, False);
    end;
  end else
  begin
    Result := GetCursor;
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
var
  CurPosX, CurPoxY: Integer;
  MyCursor: TIcon;
  pIconInfo: TIconInfo;
begin
  MyCursor := TIcon.Create;
  try
    MyCursor.Handle := GetCursorHandle;
    // Retrieves information about the specified cursor. 
    // Informationen ьber den Mauszeiger auslesen 
    GetIconInfo(MyCursor.Handle, pIconInfo);
    CurPosX := pIconInfo.xHotspot;
    CurPoxY := pIconInfo.yHotspot;
    // Draw the Cursor on the form 
    // Den Mauszeiger auf die Form zeichnen 
    Canvas.Draw(CurPoxY, CurPoxY, MyCursor);
  finally
    MyCursor.ReleaseHandle;
