// .SECTION Description
24
// An implementation of a QSortFilterProxyModel tailored for hierarchical
25
// models. It allows you to filter the model based on the content in a
26
// certain column of a certain level in the tree. Indices above that level
27
// in the tree are retained. Indices below the level are kept if their
28
// ancestor at the tree level is kept.
