Validate e-mail with QRegularExpression

[guidupas]

Hello!

I am having a problem to validate an e-mail with QRegularExpression.

I am trying with me@me.com an it returns false

bool regExpressionRetorno::validaEmail(QString email)
{
    bool retorno = true;
 
    qDebug() << email;
 
    QRegularExpression regex("\\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,4}\\b");
 
    if(!regex.match(email).hasMatch())
    {
        retorno = false;
    }
 
    return retorno;
}

bool regExpressionRetorno::validaEmail(QString email)
{
    bool retorno = true;

    qDebug() << email;

    QRegularExpression regex("\\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,4}\\b");

    if(!regex.match(email).hasMatch())
    {
        retorno = false;
    }

    return retorno;
}
