[Interest] Upgrade to Qt 5 -- pros and cons?

[Pritam Ghanghas]

Hi

I would also like to know the status of Qt5 with regard to cross flatform desktop application.
In particular I keep seeing posts on the mailing list that talk about animations and openGL Drivers.

Here is my main concern, can we do native looking cross platform applications with Qt5 that do not suffer from strange combinations of Graphics hardware.  And what is the preferred way of doing such native looking applications in Qt5, qml components, Qtwidgets?

Regards,
Pritam

Subject: [Interest]  Upgrade to Qt 5 -- pros and cons?

Hello List!

What would be the pros and cons of upgrading from Qt 4 to Qt 5?  In
particular, are there any good reasons not to do so?

I am considering upgrading various things I use -- compilers, libraries, etc.
(My main motivation is to use more of the c++11 features by running gcc
with "-std=c++11", but I will ask about that in particular in separate post.)
I am using Qt 4, and have no particular reason to change, but if I am going
to go through the work of this upgrade process, it would seem to make
sense to upgrade to the "latest and greatest" version of Qt, unless there
is some compelling reason not to.

I use Qt for very basic desktop applications.  There are a lot of things I
am not using (qml, webkit, arthur, and dbus come to mind).  I do use qwt
(currently version 6.0.1, but I will ask about qwt in particular in a separate
post).  I am currently using mingw-w64 (one of Ruben's builds), and would
stick with that unless there were good reason to change.

For what I've been doing I haven't felt that is would be worth the bother to
upgrade, but since I'll be rebuilding everything anyway, maybe now is the
time.  Are there any big hassles I should expect?  I don't mind doing some
limited porting work, but I wouldn't want to have to deal with major re-writes.

Any advice on the Qt 4 --> 5 transition would be greatly appreciated.
