The ones you listed are the ones that were there really early in the
process, even before I joined the effort :) I think these files
haven't been touched for a long long time now, at least I've never
touched them. Probably it was mainly Marius (Monsen) when he started
thinking about the project...sorry but I don't know enough about this
phase of the project to give you more information.. :(

Good question. IMHO we should give some love to the ItemView system for Qt5...

Yes and Yes. The idea since the beginning was to share the business
logic between QWidgets and the new QML ones as this is the part of
QWidgets that has a lot of history and that covers a lot of corner
cases.

The project suffered a little bit due to this concept as nobody wanted
to touch QWidgets and people started to slowly replace the c++ code
(like the 'range model' that came from the slider's logic) with at
most JavaScript code because it was simpler and easier to maintain.
Maybe this is a topic for Qt summit, but despite my opinion on this
matter I don't see any possible change on this strategy as a lot of
people agreed with it and seems happy with it...

Summary: today's qt components are a set of APIs
(http://bugreports.qt.nokia.com/browse/QTCOMPONENTS-200) that widget
developers should follow (ie Symbian, MeeGo and Plasma components
follow that API), and research about the desktop case (mainly by Oslo
guys so I can't say much here) and accessibility.

Cheers,
