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

[Roland Knall <rknall@xxxxxxxxx>]

Hi Paul

I know what you want to achieve, but I really think this way around it is a very bad idea (as I mentioned in the past). The plugin-dissector code still runs in the epan context, and there it does not have a Qt reference it can apply for. 

The GUI part of the plugin is another question, but for that you find the code in the pluginifdemo, where the selection is taking place in the uihandler wrapper, which has to decide if it should create a QApplication context or reuse Wiresharks context. 

cheers,

Roland

It's registering as a dissector but it doesn't add to the tree or anything like that.  It's for the Syncro project I'm working on; as per Gerrit, although I have completely rewritten the code since the last patch set.

"Plugin" and "true dissector" aren't opposite.  Did you mean "post-dissector" rather than "plugin", as in "it's a plugin post-dissector"?

Perhaps we need to have separate directories for plugins that contain GUI code and plugins that don't.
