QTableView from SQLite, empty!

[jacek]

QSqlRelationalTableModel model;

model.setTable("tracks");
model.setEditStrategy(QSqlTableModel::OnManualSubm it);
model.select();

setTable(&model);

You create the model on the stack, so it gets destroyed as soon as it goes out of scope, leaving a dangling pointer behind. Better create that model on the heap (i.e. using the new operator).
