macOS - TListView SubItemImages only in first column

[sardu]

Hi,
recently i've been working on porting my existing project to the macOS platform.
The first problem i ran into regards TListView component.

I use a TListView for displaying my dataset and i need to use some small images in some columns.

The code i've been using for testing is this:

Code: Pascal  [Select][+][-]

1. var
2.   LI: TListItem;
3.   i: Integer;
4. begin
5.   ListView1.ViewStyle := vsReport;
6.   for i := 0 to 1 do
7.     with ListView1.Columns.Add do
8.       Caption := 'Column ' + IntToStr(i);
9.  
10.   for i := 0 to ImageList1.Count - 1 do
11.   begin
12.     LI := ListView1.Items.Add;
13.     LI.Caption := Format('Item %d', [i]);
14.     LI.ImageIndex := i;
15.     LI.SubItems.Add(Format('SubItem %d', [i]));
16.     LI.SubItemImages[0] := i; // SubItems[ColumnIndex] := ImageIndex;
17.   end;
18. end;
19.  

and it should be giving the result shown here: https://i.stack.imgur.com/rWSy8.png.

If i run this snippet of code in Windows or Linux, it works just fine,
but if i run it in macOS (Sierra - 10.12.4) the icons appear only in the first column.   

Anyone has experienced anything like this?
I don't know what to do 

Thanks in advance to anybody,
R.

P.S. i'm using the latest release of Lazarus 1.6.4 on all three platforms.

Yes, it's a known bug.

I don't know what to do 

If you are an experienced programmer, you can try to fix the bug, or you can switch to VirtualStringTree which will work under osx too.
