How to implement QAbstractTableModel model linking?

Question

Python

What is the best way to implement one-to-many (or master-slave) model communication for QAbstractTableModel? Models will receive data through the Restful API. I wanted that when a record was selected in the master table, the slave tables were updated.

Answer 1

Models are not involved at all here, this is a matter of interaction between views - on a signal from the view of the main table, you need to update the data in the models of child tables.

Answer 2

A proxy that catches selectionchanged and updates itself, updating all slave views.
