get current item from QCompleter

[evgenM]

i have QCompleter and when i start completion i need to get current(first) item from popup list.

some code :

//CompleterModel == QStandardItemModel
//mComplet is QCompleter
//
showCompleter();
if (mComplet->popup()->isVisible())
{
  QModelIndex index = mComplet->popup()->currentIndex();
  if (index.isValid())
  {
     CompleterModel* model = (CompleterModel*)mComplet->model();
     if (model)
     {
	   QStandardItem* item = model->itemFromIndex(index);
	   if (item)
	        cout <<"item OK"<<endl;
	   else
	        cout <<"item Error"<<endl;
     }
}

//CompleterModel == QStandardItemModel
//mComplet is QCompleter
//
showCompleter();
if (mComplet->popup()->isVisible())
{
  QModelIndex index = mComplet->popup()->currentIndex();
  if (index.isValid())
  {
     CompleterModel* model = (CompleterModel*)mComplet->model();
     if (model)
     {
	   QStandardItem* item = model->itemFromIndex(index);
	   if (item)
	        cout <<"item OK"<<endl;
	   else
	        cout <<"item Error"<<endl;
     }
}

To copy to clipboard, switch view to plain text mode 

so this function return "item Error" -- what's wrong?? (i think problem from completer sorting, but how to get proxy model?
