It's ported to C++ not very accurately. May be my way of code formatting

(aligning "end" not by "begin" but by "if" or "for") confused you.

Here is the fixed version:

- removed {} for

if(rve->RVData->GetItemStyle(rve->RVData->DrawItems->Items[DItemNo]->ItemNo)

==rvsListMarker)

- added {} for the second for

- added break in the second for

- changed condition for the second for.

I made these changes in the newsgroup readed and did not test them, so may

be I missed something.

bool MoveToLineCol(TCustomRichViewEdit *rve, int Line, int Col)

{

  int i, DItemNo, DOffs;

  bool Result = False;

  DItemNo = -1;

  DOffs   = -1;

  for(i = 0; i<rve->RVData->DrawItems->Count; ++i)

  {

    if(rve->RVData->DrawItems->Items[i]->FromNewLine)

    {

      --Line;

      if(Line == 0)

      {

        DItemNo = i;

        break;

      }

    }

  }

  if(DItemNo<0)

    return Result;

if(rve->RVData->GetItemStyle(rve->RVData->DrawItems->Items[DItemNo]->ItemNo)

==rvsListMarker)

    ++DItemNo;

  if(GetDItemLength(rve, DItemNo)+1>=Col)

  {

    DOffs = rve->RVData->GetOffsBeforeDrawItem(DItemNo)+Col-1;

    Result = True;

  }

  else

  {

    Col -= GetDItemLength(rve, DItemNo)+1;

    for(i = DItemNo+1; i<rve->RVData->DrawItems->Count; ++i)

    {

        if(rve->RVData->DrawItems->Items[i]->FromNewLine)

          return Result;

        if(GetDItemLength(rve, i)>=Col)

        {

          DItemNo = i;

          DOffs = rve->RVData->GetOffsBeforeDrawItem(DItemNo)+Col;

          Result = True;

          break;

        }

      Col -= GetDItemLength(rve, i);

    }

  rve->RVData->DrawItem2Item(DItemNo, DOffs, DItemNo, DOffs);

  bool focused = rve->Focused();

  rve->SetSelectionBounds(DItemNo, DOffs, DItemNo, DOffs);

  rve->Invalidate();

  return Result;
