示例1: validate
QValidator::State QRegularExpressionValidator::validate(QString &input, int &pos) const
{
Q_D(const QRegularExpressionValidator);
// We want a validator with an empty QRegularExpression to match anything;
// since we're going to do an exact match (by using d->usedRe), first check if the rx is empty
// (and, if so, accept the input).
if (d->origRe.pattern().isEmpty())
return Acceptable;
const QRegularExpressionMatch m = d->usedRe.match(input, 0, QRegularExpression::PartialPreferCompleteMatch);
if (m.hasMatch()) {
return Acceptable;
} else if (m.hasPartialMatch()) {
return Intermediate;
} else {
pos = input.size();
return Invalid;
