Detailed Description

A QSortFilterProxyModel that hides data nodes matching one or more predicates.

This proxy model filters rows from a source model (typically a DataStorage-backed model) by evaluating a set of mitk::NodePredicateBase instances. If any predicate returns true for a given data node, the corresponding row is hidden.

Checks whether a predicate is currently in the filter list.

Parameters

[in]

pred

The predicate to check for.

Returns

True if the predicate is present, false otherwise.
