[Lazarus] How to populate a TListView programatically
Hello Everyone, I tried going through the fpc documentation and did some searching on Google and found this video on youtube: https://www.youtube.com/watch?v=ohfG7KISNq0 The video did help me to understand what to do in the Lazarus IDE but I am unable to find any code that shows me how to populate a TListView programmatically/dynamically? Does anyone have any example code that populates a Listview component through code please?

This is exactly what I was looking for. It is the subitems that was giving
me a real problem.
