[Interest] Problem using QTcpSocket with large amounts of data

[Christian Dähn]

Hi,

I wrote you some examples for sending QImages etc. into the Qt-Project forum
thread.

The examples are take from an industral imaging framework I developed - so it's
guaranteed to work with even hughe image data (> 100 MB) and can be easily
extended
to use even multiple different Qt data types in one message, e.g.:

QByteArray buffer;
QImage image;
QVariantHash properties;


QDataStream out(&buffer);
out << int(0);
out << image;
out << properties:

ciao,
Chris
