QCompleter custom model not working

[haris123]

I have to use Qcompleter with custom data one is text and other is some id.

    QStringList cities;
    cities << "Moscow" << "London" << "Las Vegas" << "New York"<< "New York";
    QStringList ids;
    ids << "0" << "1" << "2" << "3"<< "4";

    completer_model *cModel = new completer_model();
    cModel->populateData(ids,cities);

    QCompleter *completer1 = new QCompleter(this);
    ui->lineEdit->setCompleter(completer1);
   completer1->setModel(cModel);

And I have implemented custom model like below.

completer_model::completer_model(QObject *parent)
    : QAbstractListModel{parent}
{

}

int completer_model::rowCount(const QModelIndex &parent) const{
    return data_list.count();
}


QVariant completer_model::data(const QModelIndex &index, int role) const{
    int r = index.row();

    if (!index.isValid()) return QVariant();
     if (role == Qt::DisplayRole) {
               return  data_list[r].display_str;
     }
   return QVariant();


}


void completer_model::populateData(QStringList display_str, QStringList ids){

    for(int i=0;i<display_str.length();i++){
        completer_model::beginResetModel();

        algo_creation_search_box_model_struct tmp;
        tmp.display_str =display_str[i];
        tmp.id=ids[i];
        data_list.append(tmp);
        completer_model::endResetModel();

    }
}

But when I type no popup shows.

@haris123 said in QCompleter custom model not working:

QCompleter *completer1 = new QCompleter(this);
ui->lineEdit->setCompleter(completer1);

I think you need to set the model as well:
completer1->setModel(cModel);

@mpergand Sorry to not included the full code, I already done that. But the result is same, no popup came while start typing.
