How show only part of elemensts of list view?

[Subuday]

I have list model and I need to show first 10 elements. Also I use qml.

#include "langlistmodel.h"

LangListModel::LangListModel(QObject *parent):
    QAbstractListModel(parent)
{

}


int LangListModel::rowCount(const QModelIndex &parent) const
{
    if (parent.isValid()) {
        return 0;
    }

    return listData.size();
}

QVariant LangListModel::data(const QModelIndex &index, int role) const
{
    if (!index.isValid()) {
        return QVariant();
    }

    switch (role) {
    case IDRole:
        return listData.at(index.row()).value("id");
    case NameRole:
        return listData.at(index.row()).value("name");
    default:
        return QVariant();
    }
}

QHash<int, QByteArray> LangListModel::roleNames() const
{
    QHash<int, QByteArray> roles = QAbstractListModel::roleNames();
    roles[NameRole] = "name";
    roles[IDRole] = "IDLang";

    return roles;
}

void LangListModel::add(const QMap<QString, QString> &unit)
{
    beginInsertRows(QModelIndex(), listData.size(), listData.size());
    listData.append(unit);
    endInsertRows();
}

int LangListModel::size() const
{
    return listData.size();
}

void LangListModel::clear()
{
    beginRemoveRows(QModelIndex(), 0, listData.size());
    endRemoveRows();
    listData.clear();
}

  ListView {
     id: mentorsList
     model: filterModel
     footer: footerAndHeader
     anchors.fill: parent
     spacing: 2
     cacheBuffer: 2
     clip: true

......// Some Code
}

Hi,

Use a proxy model and implement the filterAcceptsRow to accept only the 10 first object.
