Actually I do know the differences. :-) And I do see a gradual trend
towards using QML-like technology in desktop applications.
I ask you this: If QWidget is so stable (i.e. did not change much between
Qt3 and Qt4), why do Qt4/KDE4 applications always use more screen space to
display less information? Why do KDE4 applications tend to require more
mouse clicks for each operation?
Can you state 100% that the Qt4 developers did not modify widget
parameters to be touch friendly? You would have needed to be on the Qt4
development team to be able to state this. :-)
Note that I am not claiming to know for certain the causes of the Qt4
widget bloat. All I do know is that it is present, it can be quantified,
and it is very hard to remove.

I'm sorry but you are very
badly informed. The technology provided by Qt
for
mobile development is called QML. It is not a widget toolkit in the
classic
way but more like HTML 5 + JavaScript. I recommend to just read a little
bit
about it :-) This technology allows you as the developer to decide how
large
e.g. a button is. In Plasma we use the same widget API just with different
backend for desktop and touch allowing us to have large buttons for touch
and
normal buttons for mouse/keyboard driven environments like a desktop.
Now your screenshot shows two applications not using QML, two applications
not
designed for touch. Aaron already pointed out that QWidget is a very
stable
area and has not changed at all.
I am sorry to say, but you really have to read a little bit about the
technology behind before doing bold statements. It's one of the things I
criticised in my blog post as you might have noticed - at least I hope so
:-)

Martin Anyway the code path in question has been
reworked in 4.8 and uses now
evil
technology coming from mobile devices ;-)
I know that this is sarcasm, but it seemed a good place to jump in to
the
thread... :-)
One of the major complaints I have against mobile technology is the
widgets in use on mobile platforms. As a whole, they tend to be larger
and have more limited interactivity due to the assumption that they need
to (and in fact can only) be tapped with a finger.
