[SailfishDevel] Show limited items in listview

[Sylvain B.]

Hi,
Filtering is done by overriding the filterAcceptsRow() method: https://doc.qt.io/qt-5/qsortfilterproxymodel.html#filterAcceptsRow

Objet : [SailfishDevel] Show limited items in listview

Hello.
I want to show only limited count of items from in ListView.
I create QSortFilterProxyModel subclass and reimplement rowCount method. But
this doesn't work.
If I return some number from rowCount - view doesn't show anything. If I
return QSortFilterProxyModel::rowCount(parent) - ListView show all elements
from model.

// Show all(7) elements from source model
int LimitProxyModel::rowCount(const QModelIndex& parent) const
{
    return QSortFilterProxyModel(parent);
}

// Show all(7) elements from source model
int LimitProxyModel::rowCount(const QModelIndex& parent) const
{
    int count = sourceModel()->rowCount(parent);
    return count;
}

// Show nothing
int LimitProxyModel::rowCount(const QModelIndex& parent) const
{
    int count = sourceModel()->rowCount(parent);
    return 7;
}

// Show nothing
int LimitProxyModel::rowCount(const QModelIndex& parent) const
{
    return 7;
}

Have you any ideas?
Thank you
