Hi,<br>
Filtering is done by overriding the filterAcceptsRow() method: <a href="https://doc.qt.io/qt-5/qsortfilterproxymodel.html#filterAcceptsRow" id="LPNoLP925614">

<div class="PlainText">Hello.<br>
I want to show only limited count of items from in ListView.<br>
I create QSortFilterProxyModel subclass and reimplement rowCount method. But <br>
this doesn't work. <br>
If I return some number from rowCount - view doesn't show anything. If I <br>
return QSortFilterProxyModel::rowCount(parent) - ListView show all elements <br>
from model.<br>
<br>
// Show all(7) elements from source model<br>
int LimitProxyModel::rowCount(const QModelIndex& parent) const<br>
{<br>
return QSortFilterProxyModel(parent);<br>
}<br>
<br>
// Show all(7) elements from source model<br>
int LimitProxyModel::rowCount(const QModelIndex& parent) const<br>
{<br>
int count = sourceModel()->rowCount(parent);<br>
return count;<br>
}<br>
<br>
// Show nothing<br>
int LimitProxyModel::rowCount(const QModelIndex& parent) const<br>
{<br>
int count = sourceModel()->rowCount(parent);<br>
return 7;<br>
}<br>
<br>
// Show nothing<br>
int LimitProxyModel::rowCount(const QModelIndex& parent) const<br>
{<br>
return 7;<br>
}<br>
<br>
Have you any ideas?<br>
Thank you<br>
<br>
