\fn void QStringList::sort()
\fn void QStringList::sort(Qt::CaseSensitivity cs)
Sorts the list of strings in ascending order (case sensitively).
Sorts the list of strings in ascending order.
If \a cs is \l Qt::CaseSensitive (the default), the string comparison
is case sensitive; otherwise the comparison is case insensitive.
Sorting is performed using Qt's qSort() algorithm,
which operates in \l{linear-logarithmic time}, i.e. O(\e{n} log \e{n}).
