.SH DESCRIPTION
A convenience class for input streams.
.PP
For simple tasks, code should be simple. Hence this class is a shorthand to avoid passing the \fImode\fR argument to the normal QTextStream constructors.
.PP
This makes it easy for example, to write things like this:
.PP
.nf
.br
    QString data = "123 456";
.br
    int a, b;
.br
    QTextIStream(&data) >> a >> b;
.fi
.PP
See also QTextOStream.
