TCustomShellTreeView.GetPath vom Linker entfernt

[Gina]

Hallo,

ich hab mir mal die entsprechenden Routinen in der ShellCtrls näher angeschaut, konnte aber keinen Hinweis dazu entdecken, warum der Linker das entfernt. Hat jemand eine Idee? Oder wie man das evtl. selbst schreiben könnte, damit es funktioniert?

Delphi-Quellcode:

protected
  //....  
  property Path: string read GetPath write SetPath;
  //...
function TCustomShellTreeView.GetPath: String;
begin
  if SelectedFolder <> nil then
    Result := SelectedFolder.PathName
  else
    Result := '';
end;

procedure TCustomShellTreeView.SetPath(const Value: string);
var
  P: PWideChar;
  NewPIDL: PItemIDList;
  Flags,
  NumChars: LongWord;
begin
  NumChars := Length(Value);
  Flags := 0;
  P := StringToOleStr(Value);
  try
    OLECheck(DesktopShellFolder.ParseDisplayName(
        0,
        nil,
        P,
        NumChars,
        NewPIDL,
        Flags)
     );
    FUpdating := True;
    SetPathFromID(NewPIDL);
  except on EOleSysError do
    raise EInvalidPath.CreateFmt(SErrorSettingPath, [Value]);
  end;
  FUpdating := False;
end;

procedure TCustomShellTreeView.SetPathFromID(ID: PItemIDList);
var
  I: Integer;
  Pidls: TList;
  Temp, Node: TTreeNode;
begin
  if FUpdating or (csLoading in ComponentState)
    or ((SelectedFolder <> nil) and SamePIDL(SelectedFolder.AbsoluteID, ID)) then Exit;
  FUpdating := True;
  Items.BeginUpdate;
  try
    Pidls := CreatePIDLList(ID);
    try
      Node := Items[0];
      for I := 0 to Pidls.Count-1 do
      begin
        Temp := FolderExists(Pidls[I], Node);
        if Temp <> nil then
        begin
          Node := Temp;
          Node.Expand(False);
        end;
      end;
      Node := FolderExists(ID, Node);
      Selected := Node;
      if Assigned(Node) then
      begin
        if Assigned(FListView) then
          FListView.TreeUpdate(TShellFolder(Node.Data).AbsoluteID);
        if Assigned(FComboBox) then
          FComboBox.TreeUpdate(TShellFolder(Node.Data).AbsoluteID);
      end;
    finally
      DestroyPIDLList(Pidls);
    end;
  finally
    Items.EndUpdate;
    FUpdating := False;
  end;
end;

procedure TCustomShellTreeView.SetPath(const Value: string);
var
  P: PWideChar;
  NewPIDL: PItemIDList;
  Flags,
  NumChars: LongWord;
begin
  NumChars := Length(Value);
  Flags := 0;
  P := StringToOleStr(Value);
  try
    OLECheck(DesktopShellFolder.ParseDisplayName(
        0,
        nil,
        P,
        NumChars,
        NewPIDL,
        Flags)
     );
    FUpdating := True;
    SetPathFromID(NewPIDL);
  except on EOleSysError do
    raise EInvalidPath.CreateFmt(SErrorSettingPath, [Value]);
  end;
  FUpdating := False;
end;

    or ((SelectedFolder <> nil) and SamePIDL(SelectedFolder.AbsoluteID, ID)) then Exit;
  FUpdating := True;
  Items.BeginUpdate;
  try
    Pidls := CreatePIDLList(ID);
    try
      Node := Items[0];
      for I := 0 to Pidls.Count-1 do
      begin
        Temp := FolderExists(Pidls[I], Node);
        if Temp <> nil then
        begin
          Node := Temp;
          Node.Expand(False);
        end;
      end;
      Node := FolderExists(ID, Node);
      Selected := Node;
      if Assigned(Node) then
      begin
        if Assigned(FListView) then
          FListView.TreeUpdate(TShellFolder(Node.Data).AbsoluteID);
        if Assigned(FComboBox) then
          FComboBox.TreeUpdate(TShellFolder(Node.Data).AbsoluteID);
      end;
    finally
      DestroyPIDLList(Pidls);
    end;

Tausend Dank, Gina.
