I didn't manage to select the first item of the completer when the popup is displayed in PopupCompletion mode.
My current code that doesnt work:

```
completer->setCompletionPrefix(text);
QItemSelectionModel* sm = new QItemSelectionModel(completer->completionModel());
sm->select(completer->completionModel()->index(0,0), QItemSelectionModel::Select);
completer->popup()->setSelectionModel(sm);

```

Any suggestions?
