when QBuffer emits readyRead signal?

[mastupristi]

Hi

Reading QBuffer documentation:

QBuffer emits readyRead() when new data has arrived in the buffer.

The question is: how new data can arrive in the buffer?
I mean, I declared a QBuffer:

QByteArray byteArray;
QBuffer buffer(&byteArray);
buffer.open(QIODevice::ReadWrite);

QByteArray byteArray;
QBuffer buffer(&byteArray);
buffer.open(QIODevice::ReadWrite);

To copy to clipboard, switch view to plain text mode 

In my thought new data is considered arrived if I write data in the byteArray directly:

byteArray.append("hallo");

byteArray.append("hallo");

To copy to clipboard, switch view to plain text mode 

but readyRead() is never called

so how new data can arrive in the buffer to make readyRead() be emitted?

best reagards
