Try something like this. Use the data method of index. bool CustomProxyModel::filterAcceptsRow(int source_row, const QModelIndex &source_parent) const { const QModelIndex sourceIndex = sourceModel()->index(source_row, 0, source_parent); // Some how get the the role you require. const QString filterElement = sourceIndex.data(role).toString(); return(filterElement.toLower().startsWith(m_filterText)); }

@JonB said in QSqlTableModel Filter: 'First name' LIKE '%Jacob%' lol, was checking the condition and haven't noticed that, because of the use of DataBase::COLUMN_FIRSTNAME

@J-Hilk said in How to get ALL the keyboard pressed keys WITHOUT RESTRICTION OR FILTER?: Inside main.cpp install an eventfilter on the Q(GUI)Application Thank you very much, this was exactly what I needed!

@Kofr mapFromSource() and mapToSource() are enough. The default implementation should depend on these methods only.

@mmoerdijk since Qt 5.10 there is a recursiveFilteringEnabled property on a QSortFilterProxyModel, which does exactly this.

Please let me know if there is any update on this. Mike
