Yes, as I said in the previous post, the modified code inserts not all links, so they are mismatched.

The solution: when adding links to the list (in RichView1), do not add the link targets as tags. Use the link index instead.

The code below is for the latest version of TRichView, where tags are strings.
For older versions, remove StrToInt and IntToStr, and exclude rvoTagsArePChars from RichView1.Options.

Code: Select all

procedure TFmain.EnumLinksProc(RVData: TCustomRVData; ItemNo: Integer;
  var UserData1: Integer; const UserData2: String;
  var ContinueEnum: Boolean);
var StyleNo: Integer; 
begin 
  StyleNo := RVData.GetItemStyle(ItemNo); 
  if RVData.GetRVStyle.TextStyles[StyleNo].Jump and 
     (RVData.GetRVStyle.TextStyles[StyleNo].Color =  clGreen) then 
    RichView1.AddNLTag(RVData.GetItemText(ItemNo), RVData.GetItemStyle(ItemNo),
      0, IntToStr(UserData1));
  if RVData.GetItem(ItemNo).GetBoolValueEx(rvbpJump, RVData.GetRVStyle) then
    inc(UserData1);
  ContinueEnum := True; 
end;
Now, we need to modify RichView1.OnJump and OnItemHint:

Code: Select all

procedure TFmain.RichView1Jump(Sender: TObject; id: Integer);
var RVData: TCustomRVFormattedData;
    ItemNo: Integer;
begin
  RichView1.GetJumpPointLocation(id, RVData, ItemNo);
  id := StrToInt(RVData.GetItemTag(ItemNo));
  // here, id = link index in RichViewEdit
  RichViewEdit1.GetJumpPointLocation(id, RVData, ItemNo);
  RVData := TCustomRVFormattedData(RVData.Edit);
  RVData.SetSelectionBounds(ItemNo, RVData.GetOffsBeforeItem(ItemNo),
    ItemNo, RVData.GetOffsAfterItem(ItemNo));
  RichViewEdit1.SetFocus;
end;

Code: Select all

procedure TFmain.RichView1ItemHint(Sender: TCustomRichView;
  RVData: TCustomRVData; ItemNo: Integer; var HintText: String);
var id, LItemNo: Integer;
    LRVData: TCustomRVFormattedData;
begin
  if RVData.GetItem(ItemNo).GetBoolValueEx(rvbpJump, RVData.GetRVStyle) then begin
    id := StrToInt(RVData.GetItemTag(ItemNo));
    // here, id = link index in RichViewEdit
    RichViewEdit1.GetJumpPointLocation(id, LRVData, LItemNo);
    HintText := LRVData.GetItemTag(LItemNo);
  end;
end;
