Hi Vadym,
My book shows how to do master-detail in the context of a SQL database
(e.g. pp. 463), but the same technique can be applied to any pair of
table models.
One approach is to connect the master table's selectionModel()'s
currentRowChanged(QModelIndex,QModelIndex) signal to a custom slot.
Then, in the custom slot you handle the populating of the detail table,
for example, by filtering (which you can do with a sort/filter proxy
model).
