We’re going to running remote GUI on a few PCs, all communicating with a central server where the main application is running. Instead of hacking our own manual network protocol and marshalling layer for button presses and various events, my hope is that this could be solved more cleverly somehow.

Indeed, it’d be nifty if you could autogenerate network proxies for these Qt objects, or somehow connect signals/slots across an RPC interface, or something like that.

  • Writing a code generator based on Qt’s .ui files should be doable, but maybe someone else has tried this before (with or without success)?

  • Another idea would be to use PyQt and some mechanism in python for networked proxy objects.

  • Failing Qt specific stuff, how does one solve remote GUI in general?

(Using web server/client is not ok, as we need our Qt Style, and probably a more speedy GUI with more fancy widgets. )

    The Qxt extension library for Qt has a QxtRPCPeer class

    QxtRPCPeer is a tool that encapsulates
    Qt signals and transmits them over a
    network connection. The signal is
    subsequently re-emitted on the
    receiving end of the connection.

    Last Edit (Relevant OP’s comment posted below on Feb 26 ’11 at 16:23):

    An update 1,5 years after. We’ve been using QxtRPCPeer in our production software for a year now. No glitches whatsoever.

    Last Edit (By OP on 2015-05-22):

    LibQxt is not maintained anymore, as of 0.6.2, as keeping up with the internal API changes is too much work for the authors. Some parts might still be usable but you’d have to maintain it yourself.
