示例1: QStringList_indexOf

/*!
    \fn int QStringList::indexOf(const QRegularExpression &re, int from) const
    \overload
    \since 5.0

    Returns the index position of the first match of \a re in
    the list, searching forward from index position \a from. Returns
    -1 if no item matched.

    \sa lastIndexOf()

int QtPrivate::QStringList_indexOf(const QStringList *that, const QRegularExpression &re, int from)
{
    if (from < 0)
