C++ (Cpp) stringClass Examples

Example #1

File: qsenv.cpp Project: vamoros/eneboo

QSClass *QSEnv::classByName(const QString &n)
{
    QSClass *t = 0;

    // ### use an expandable dict
    if (n == QString::fromLatin1("Null"))
        t = nullClass();
    else if (n == QString::fromLatin1("Number"))
        t = numberClass();
    else if (n == QString::fromLatin1("Boolean"))
        t = booleanClass();
    else if (n == QString::fromLatin1("String"))
        t = stringClass();
    else
        qDebug("TypeNode::rhs: Ignoring unknown type %s.", n.ascii());
