Funny, I'm using the same technique in my block editor[1]. Rather than using the complex table/tree-like data structure of QAbstractItemModel[2], I'm using QAbstractListModel[3] (flat list) with a property called indentLevel[4] for each delegate. It works out great. I still need to manage parent child relationships (it makes rendering changes easier using recursive function) so I keep variables for that, but the "fake tree" look, as I like to call it, simply uses the indentLevel property which is determined by the amount of whitespace/tabs at the start of a line in the underlying plaintext data.
