I've written a basic generic QVariantMap server/client set of classes.
I know this code is probably rather rough - might just be better used
as an "example" or a starting point on writing your own. Take it for
what it's worth, here's the code:
https://code.google.com/p/livepro/source/browse/trunk/varnet
The "server" end would use VariantMapServer (derived from QTcpServer)
and connect to the "receivedMap(QVariantMap)" signal to receive input
from clients, and use the "sendMap(QVariantMap)" slot to send data to
the clients.
The "client" end would use the "VariantMapClient" class which offers
the same pair of signal and slots to send/receive QVariantMaps.
Hi Josiah,
Thanks a lot, I'll check this out.
Best,
Jonathan

I've written a few of those - I always wrote the protocol myself
on top of
QTcpSocket or QLocalSocket.
The protocol you are using right now is probably a good starting
point -
you'll just have to write your command parser yourself.
I recommend using a registry(*) for your main items and use their
IDs just
like you used the Tk item/widget names as "command", then
interpret the
remainder of the commands - it usually is a simple matter of using
QString::split and handing the result to some hierarchy of methods
to do
the evaluation of the components.
(*) QMap<int,QGraphicsItem*>registry; or the better
QMap<int,QPointer<MyPdItemClass> >; with MyPdItemClass containing
enough
logic to work in the context of your program as well as taking care of
item deletion, etc.
I would also recommend updating the protocol to exchange high-level
information instead of actual widget commands - more like "item1234
setActive 1" instead of ".item1234 setColor green".
