So I have to create a new package in Lazarus, then add the sourcefile
to this and compile + install?

Do Lazarus component sourcefiles also have a Register procedure thta
tells Lazarus that it is in fact a component?

I have to get the darn thing through the compilation first of course
and now I have problems with the properties of a TListView in Delphi
being different from those of the Lazarus TListView. The Delphi custom
component is a visual one, a descendant from TListView with built-in
properties and methods/events like ItemIndex, OnItemSelect, sorting
and more.

Right now I have reached error messages because of:
StateIndex and CustomSort. Still struggling...
