The reason why I am taking this approach in the first place is because they did not like the idea of having new signals added to KFileItemModel and DolphinView. See the discussion @ https://git.reviewboard.kde.org/r/106289/.

I'm against signals and public accessors, but the 'friend' solution looks OK. A private accessor is not really needed because DolphinPart can just access m_view->m_model directly then.

Please add a comment that explains why it needs to be a friend (for examples, do 'grep "friend class" * -r' in Dolphin's source).

This implementation does not add new signals to KFileItemModel and DolphinView classes as the previous solution. Instead it relies on the QObject's introspection to look for KDirLister and connect to the desired signals.

However, unlike that implementation, this one will not suffer from sudden and unexpected changes in Dolphin's code changes because it is closer to the source and it looks for the directory lister directly in KFileItemModel. This is something that cannot be done at the plugin level because it would require the plugin to link against dolphin.
