Wireshark · Wireshark-dev: Re: [Wireshark-dev] Checking for Qt in a dissector

[Roland Knall <rknall@xxxxxxxxx>]

If you just need it for the code showing some toolkit function or plugin functionality, there is an example code in the pluginifdemo for that.

As the guys said, it cannot be done from the dissector itself, as this will need some sort of reference from libwireshark, and that is a very bad idea.

Hi Pascal,

That won't work in this case.  It's actually a plugin rather than a true dissector - I didn't describe it well.  It uses Qt code so it definitely will only work with Wireshark 2.x.x.  Objections aside, how can it be detected?

Thanks and regards...Paul

Hi Paul,

I have a dissector that needs to confirm that it is running in a Qt environment i.e. Wireshark 2.x.x and not tshark.  What is a good way to check for this?

Sorry to say that but IMHO you should not / must not have such a need. Any dissector that would behave differently depending on the application used (command line, GTK UI, Qt UI) has a design flaw.

Dissectors should behave the same way whatever the user frontend, and taps are here to present the data to the user differently depending on the interface used.

I sincerely hope we do not expose the info you are requesting to libwireshark....

Regards,

Pascal.
