Send QImage over network

[winston2020]

Have you checked that the appropriate amount of data is ready to be read on the receiving end? The fact that you are notified there is something to be read doesn't mean there is everything to be read, maybe that's the problem?

Thank you for your help. I'm still quite new to network programming in QT. Right now I'm using QIODevice::readyRead() signal to notify my socket when to begin reading. Is that incorrect? How should I determine when the reading should begin?

I tried sending the size of the file first, but I find that readyRead() is emitted several times for each transfer.

it is ok to begin reading. the point is when to stop.
because unless you send the package size (before the image data) you will never know if the image is complete.

see network-fortuneclient for an example to wait for a complete package of network data
