Hello Werner!
After posting this I late last night found a mail correspondence with
you from June 2018 where you helped me convert this very component!

And luckily the final files were attached in the email at the end of
the conversation so I could extract them.

Meanwhile I have had to replace my old Win7 computer and lost a lot of
files in the process... :(

Anyway now I have placed the files under subversion so that will not
happen again.

So I took these files (where the naming was better with a difference
between the package and the sourcefiles) and repeated the process and
it succeeded! I now have an EasyListView component on my Lazarus

This is very good because almost all of my old GUI style Delphi
projects used the component to display data and so is crucial to being
able to port them.

The reason I had forgotten our interaction could be that at the time
in 2018 I was convalescing from a bad fall from the roof of my house
and could barely move...

I want to (hopefully again) thank you so very much for your help at
the time!
