Example Project "Custom Sort/Filter Model Example" has broken QRegExp

The regular expression "emailPattern" has no opening parenthesis for the capture group:
{{ static QRegExp emailPattern("\\w\\.@[\\w
.|file://w//]"); }}
should be
{{ static QRegExp emailPattern("(\\w\\.@[\\w
.|file://w//])"); }}
 

Alternatively, the capture group could be omitted but then the subsequent extractions of the email text must match the whole regexp: cap(0) instead of cap(1). The later solution is probably better because it is simpler.
