Using inline item editor with TListbox

[digeo]

I am using this in my application and thought it may be usefull to others.

It is a Listbox that has an inline editor to add, delete and edit items in the list box. It uses a combobox and a button on a panel that is placed inside the Listbox over the selected item.
