@QFile file(":/default.txt");
file.open(QIODevice::ReadOnly);
TreeModel model(file.readAll());
file.close();

QTreeView view;
view.setModel(&model);
view.setWindowTitle(QObject::tr("Simple Tree Model"));
view.show();@

when I paste it in main then code works (I see QTreeView with data), but when paste it in QMainWindow constructor then I see an empty QTreeView window without data.

why?
