That is true, but XML in Python isn't that hot - plainly because it's faster and a lot more flexible to interpret Python bytecode and execute it than it is to parse XML in Python and respond accordingly. I normally use a function like I stated above for generating the .py file when I'm developing but remove it and import the generated file solely when I want to distribute the script - importing a module strikes me as faster than reading an XML file to construct a GUI on the fly. Personal preference I suppose :-)

I didn't say it was faster (though it's likely not much slower); just slightly neater

I didn't say it was a big thing either, just something relatively minor. QtDesigner takes an extra step over Glade, but QtDesigner more than makes up for it in other ways.
