Why do almost all UI examples rely heavily on concrete inheritance? As I looked for tutorials, examples, and references, I kept seeing concrete inheritance come up. It is bad design and it muddles up the examples. Are they creating a function in the class for their own use or are they overriding a method? How critical is it they override it to be able to get functionality X?
PyGTK tutorial and reference were great. Everything is easily found in the reference and almost everything I needed to know was in the tutorial. Qt's reference is good, PyQt's is a bit more so-so. As for tutorials I have not found one concrete tutorial that covers 90% of what I need but instead need to jump from tutorial to tutorial depending on the specific thing I am doing. I've even done searches through source code to try and find how to use somethings but that didn't get me much.
