And "KListView" is a lot more telling? Sorry, not to me.

The only difference I see in K-vs-non-K is when you start talking about 
application-specific classes. If I see KMListView in KMail, I know it's a 
KMail-specific class, whereas KListView would be in the libraries.

True, but unlikely.

Sorry, non-issue again. I don't think "KListView" tells you it comes from 
libkdeui anymore than "ListView" unless you're familiar with our 
libraries. Take, for example, KPixmap: pixmaps are UI, so it is in 
libkdeui, right? Wrong, it is in libkdefx.

I didn't understand this one.
