+ \title QRegularExpression Example
+ \ingroup examples-widgets-tools
+ \brief The QRegularExpression example shows how regular expressions in Qt are
+ applied to text by providing an environment in which new regular expressions can be
+ created and tested on custom text strings.
+ The example makes usage of the QRegularExpression class, which has been
+ introduced in Qt 5.0. QRegularExpression implements Perl-compatible regular
+ expressions, supporting a number of advanced matching features, such as
+ case insensitive matching, multiline matching, Unicode properties selectors
+ and partial/incremental matching.
+ QRegularExpression is a big improvement over QRegExp in terms of features
+ and performance and should be used in all new code.
