Detailed Description
The class subclasses QSortFilterProxyModel. Compared to the base class, filters affect also child indexes in the base model, meaning if a certain row has a parent that is accepted by filter, it is also accepted. A distinction is made betweed directly and indirectly accepted indexes.

QVector<QModelIndex> ComponentSortFilterProxyModel::directlyAcceptedIndexes() const
Returns a list of source model indexes that were accepted directly by the filter.
[override virtual protected] bool ComponentSortFilterProxyModel::filterAcceptsRow(int sourceRow, const QModelIndex &sourceParent) const
Reimplements: QSortFilterProxyModel::filterAcceptsRow(int source_row, const QModelIndex &source_parent) const.
Returns true if the item in the row indicated by the given sourceRow and sourceParent should be included in the model; otherwise returns false.
