Transfer image problem

[jacek]

How can I collect all the image coming from the remote computer in my QByteArray before passing the image to the label ?

You need something like this:

void ClientThread :: readData()
{
     buffer.append( tcpSocket->readAll() );
     int messageSize = 0;
     do {
        messageSize = parseMessage( buffer );
        buffer.remove( 0, messageSize );
     }
     while( messageSize > 0 );
}

void ClientThread :: readData()
{
     buffer.append( tcpSocket->readAll() );
     int messageSize = 0;
     do {
        messageSize = parseMessage( buffer );
        buffer.remove( 0, messageSize );
     }
     while( messageSize > 0 );
}

To copy to clipboard, switch view to plain text mode 

There are three possibilities:

• the buffer contains only a part of a message (in this case parseMessage() should only return 0),
• the buffer contains a message followed by a part of another message (in this case parseMessage() should parse that message and return its size),
• the buffer contains an invalid message (it might happen due some communication errors or bugs on the other side).
