Use QIterator on TreeView's model

[wysota]

You don't turn a model into the view. The view's data is held in the model so if you want to iterate the items of the view, you just access the model.

for(int i = 0; i< tree->model()->rowCount(); i++){
  QModelIndex index = tree->index(i, 0); // column no 0
  doSomething(index);
}

for(int i = 0; i< tree->model()->rowCount(); i++){
  QModelIndex index = tree->index(i, 0); // column no 0
  doSomething(index);
}
