Hi all,

I was asked a question about Qt Remote Object (QtRO) as another option for graphics sharing at the webex meeting, but I couldn’t answer due to my connection environment. So I would like to mention QtRO on this thread.

Qt Remote Object is designed to enable communication between processes in a same domain originally. But it would be possible to use it across the domain if a proper backend is added. As Gunnar mentioned at that time, the purpose of QtRO is in a somewhat different level from graphics sharing because its goal is not specified to graphics (extending Qt meta-object-system to inter-process level). Thus, I think it would be preferable for generic messages or signals.

Personally I’m interested in Waltham and want to evaluate if it could be migrated to Qt Wayland as well. If it’s possible, it would be easy to switch its rendering target of HMI application base on Qt, e.g. just changing the target platform from ‘wayland’ to ‘waltham’. Recently we (The Qt Company) just started to consider inter-domain use case. So I hope to get more knowledge in this project and exchange opinions in the wiki or call.

@Alistair, if there’s something incorrect, please let us know.

Best regards,
Sales Engineer | The Qt Company

    Thanks to all who joined !
    On Thursday (yesterday), we had around 12 participants attending the 2nd 
    webex of the Graphics Sharing project.
    Eugen made a comprehensive presentation on various approaches for Graphics 
    Sharing, followed by a Q&A.
    Slide decks shown by Gunnar (GENIVI) and Eugen (ADIT) and the recording of 
    the webex are available in the wiki at: 
    The above wiki page will be the collaborative space for the project, do not 
    hesitate to populate it with your thoughts and comments.
    We are looking forward to keep digging into graphics sharing again with you 
    during next week's meeting. A calendar invite will be sent.
    Best regards
    Salutations cordiales / Best regards
