## Detailed Description

The QTextIStream class is a convenience class for input streams.

This class provides a shorthand for creating simple input QTextStreams without having to pass a mode argument to the constructor.

This class makes it easy, for example, to write things like this:

        QString data = "123 456";
        int a, b;
        QTextIStream(&data) >> a >> b;
