<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This avoids expensive layoutChange signals from QSFPM. We can only be sure
we are not filtering if filterAcceptRows isn't overridden, which we can
check if we assume sub-classes have the Q_OBJECT macro set.
This will however break sub-classes overriding filterAcceptRows without
using the Q_OBJECT macro, and using their own filter criteria. However,
this is a significant performance improvement in the common case of
KRFPM being used for string-based searching in a tree view, and the search
being unused.</pre>
