Traversing Proxy Models to get to the bottom Source Model - Video

Sometimes a view or delegate needs to ask the model providing the data (at the bottom of a proxy model stack) some questions.

In the previous video, 'Communicating between a View/Delegate and a Model' ( https://youtu.be/q6eOEz_UfTI ), I showed how custom roles can be used for this.

However, if the data isn't related to a specific cell, a better approach might be to traverse the proxy models yourself, to get to the actual source model.
This video shows this approach.
