Nothing that I know of, but if you find some method I'd be happy to look at incorporating it.

No, that's the one, rename it (get rid of the .txt extension which I had to add to allow the file to be attached) and place it in /usr/share/mbarcode/plugins/pythonqt/
Then it should just appear in the plugin settings window (if you want to disable all other plugins and only have that one running) or otherwise it will be listed in the results window when you scan an EAN/ISBN barcode.
You'll need to install pyside from extras-devel (if this script were packaged up correctly rather than just a single file, that would be a dep to be automatically installed.)
It's just Python code, take a look at it, should be pretty easy to understand what it's doing, etc.
It doesn't come up in the plugins list, I even tried rebooting the phone. When I scan a barcode there's nothing available to write to a file.

I didn't know anything about this till a few days ago when I got a card from Symantec saying I could enter their contest by using my barcode application. I remembered there was one available, downloaded mbarcode and it worked perfectly.

I've been looking at the mbarcode code and I see xml files describing the interface. I was expecting to see interface defined in QML instead.
My experience with Qt is very limited so my question would be if using xml -based description for interface (I assume those are processed by qdbusxml2cpp) is a preferable way of describing/designing user interfaces? What about QML - will that result in better performance as Qt documentation claims?

No idea about the speed claims, but I can't see how using Javascript is going to help things.

That answers you worries that xml is parsed by application at runtime - it is not. UI editor with preview is a nice tool IMHO.

@eachna:
Do you have mbarcode-plugin-pythonqtwrapper installed?
Assuming you do, try opening the settings menu (which forces the plugins to be loaded) then see if there are any error messages related to loading this plugin.
The paths all look fine, the only other possibilities are that the Python script name doesn't match the class name within (the two must match, bar the .py extension) or perhaps it has dos line endings rather than unix, which is stopping it from being loaded.
