Precondition: row must be in correct range ( 0 <= row < rowCount() )

Definition at line 83 of file PrimaryKeyProxyModel.cpp.

void Mdt::ItemModel::PrimaryKeyProxyModel::setPrimaryKey ( const PrimaryKey & pk )

Set primary key.

Precondition: pk must not be null

Definition at line 30 of file PrimaryKeyProxyModel.cpp.

void Mdt::ItemModel::PrimaryKeyProxyModel::setPrimaryKey ( std::initializer_list< int > pk )
