I'm just wondering, if the native app development support is now introduced to Windows phone 8, does this mean that we can -technically- develop Qt-based app and benefit from the QML technology?
There is a lengthy technical report on the feasibility of supporting Qt on Windows 8 here:
http://qt-project.org/wiki/Qt-5-on-Windows-8-and-Metro-UI
From the conclusions it sounds quite feasible.
A bit of an update to this old question, links:
Building Qt 5 for Windows 8 Modern UI (Windows Store Apps & Windows Phone 8)
Building and deploying your WinRT apps (Tech Preview 1)
Qt5 documentation snapshot: WinRT
So to answer the question: Yes, it's indeed technically possible. Still (start of 2014) in early stages of development, so everything does not work, project set up is clumsy etc, but looks pretty promising. No idea about when official out-of-the-box support might come to Qt 5 SDK, but Qt is open source, so you can start playing with it already.

Can we develop an application using JavaFX and run it on multiple platforms, including mobile(Android, iOS) and Desktop(Windows, Mac, Linux) as well?
Latest Oracle MAF (2.1.2) runs on both Android and iOS.

Support for Windows phones it has been in talks for a while, it will won't be long until Oracle will make it available.
JavaFX is supported on Windows, Mac and Linux. It is not supported on iOS or Android although there are third party solutions provided by the community for that (RoboVM for iOS). This might be the reason you were unable to find instructions on how to set up Android Studio with JavaFX.
Generally JavaFX 8 is very reliable on all three platforms. Please note that JavaFX 1 is an entirely different thing than JavaFX 2 and 8. Not only does it rely on JavaFX Script instead of Java, it also focusses more on browsers and mobile devices.
I am currently looking at using PySide for mobile app development. I've done a few tutorials for creating desktop applications using Pyside and loving it. I understand PySide/PyQt is a port or mapping for Qt, and is usualy behind a little bit with Qt as developers of PySide/PyQt have to keep up with whatever happens in Qt.
I particularly want to develop for Android, BlackBerry and iOS. I also understand that Qt recently added support for Windows 8, as well as the more recent BlackBerry 10 OS.
My question: How well versed is PySide/PyQt in its current state with cross mobile application development.
Does it achieve mobile development by means of the WebKit component, allowing the use of everyday HTML, CSS and JavaScript?
Would it be a better option to consider PyQt for mobile app development, or PySide?
I think its not realistic to think you can use PySide/PyQt and Python in order to make one application suitable for all those platforms.
First of all the platform you want to develop for should support your programming language (Python) as well as the graphical framework (Qt) in order to make it work. This is mostly achieved by third party developers. If Python runs on your mobile operating system this does not say you can start developing and vice versa.
Mobile development is often done with QML (Qt Modeling Language). This allows you to make really cool and fancy interfaces on many platforms. You can connect it to your own Python code to make a real working application.
At this moment Qt is working on support for mobile devices. Most mobile operating systems like iOS and Windows Phone are not supported yet for the combination Python/Qt and mostly the support for working projects is not really big in comparison to the preferred languages of the operating systems.
Here is a list of mobile OS's which support the combination Python/Qt
Link to projects if there is a good link for a starting points is available
Android: PySide for Android
or if you like to use "webviews" instead of PySide: SL4A
Blackberry 10: BB-py
Meego: Python/Harmattan Project
SailFish OS: Harmattan apps (Meego) run without any problem
For your other questions I have a shorter answer.
The webkit component is intended as a content viewer component. Its not a component for building full HTML 5 apps.
The question which bindings for Qt are better is often asked. What you need to be aware of is that the old version of PyQt did almost the same as PySide. The difference was mainly in the license! However PyQt supports now Qt 5 while PySide doesn't, so make your own choice. I think you can make beautiful apps with both of them.
i'm beginner for mobile application development. i have knowledge of C language. i want to develop some app for meego ( Nokia N9) & symbian devices. i already downloaded QT sdk.now what i want to learn for application development. C++ or QML? as i told i'm very beginner for this languages.where can i start? pls help me. thanks
What you have to do is starting by learning the programing language which corresponds with the framework you will use. Once you do that, you can start learning how to use the framework.
Qt : C++
Qt Quick : JavaScript and QML
After that, it depends on which plateforms you want to develop to :
Classic Desktop OSes (Windows, Linux, Mac) : Qt with C++ is for you. You can use Qt Quick too but for the moment it is not really made for those plateforms. Moreover, you got skills in C so starting by learning C++ and then Qt may be easier for you since C and C++ have got lots of common points.
Mobile OSes (Symbian, MeeGo) : developing in C++ may be harder on mobile OSes than on PC OSes. So you had better use Qt Quick with QML and JavaScript. Moreover, Qt Quick was made for development on mobile plateforms. Unlike Desktop OSes, you have got a real set of reusable components such as Buttons, Sliders, Scroll Bars... Those Qt Quick Components (that's their name) exist also on Desktop but they are not (until Qt5 and Qt Quick 2.0) as developed as their equivalent on Symbian and MeeGo.
Qt will always be faster and fluid but it is easier to code with Qt Quick.
You can also develop hybrid applications with both C++/Qt parts and QML/JS/Qt Quick parts but it is more advanced. This will be the next step. ;-)
I have to develop an application which requires Bluetooth and profile change functionality for Symbian phones. After spending sometime I found that following options:
Java: but java does not allow to change profile
Symbian C++: I read basics for Symbian C++ and created some basic stuffs. Symbian extended APIs provide simple APIs for Profile and Bluetooth (I haven't tested yet). But its required lot of efforts to grab these. Specially certificate singing problem. I want to test my application on different devices and wish to give my friends whom having different cellphones. But couldn't due to signing problem.
QT: I am still confused on this. Whether this platform capable to fulfill my requirement or not. Secondly which phone supports QT or not...
Honestly, I am bit frustrated while writing this. I am looking someone, experience in these matter, to guide me in this situation.
You can combine native C++ with Qt. Though you'll lose some of the cross-platform nature of Qt by mixing native C++ with it.
See the XQProfile example on Forum Nokia Wiki for mixing Qt and native Symbian C++ for profile changing.
Qt can be installed to practically all devices from S60 3rd Edition FP1 (S60 3.1) onwards. Newer device models ship with Qt preinstalled. Forum Nokia has device specifications that you can filter based on Qt availability.
QT (+ QML) is the language of choice going forward. I believe it is currently on the following phones: N8,C7,C6,E7. i version 4.6.1 with version 4.7 which has the QML support due shortly.
However if you need to target current and older devices then your only choice is Symbian C++.
I have started using Python for web development recently, it's kinda cool;
I have seen programs that are developed in QT/C++, which is good enough in terms of esthetics;
I have just noticed the new PySide project (which brings LGPL Qt license to Python and it doesn't support Windows yet).
In view of the above, I see the possibility of using Python + PyQt/PySide to develop cross platform apps in the future :) but I have several doubts right now:
Can PyQty/PySide be used to develop really complex/modern UI? Can somebody give me some points to have a look at some nice-looking screenshots of apps that are developed in Python+QT?
What about the performance of using Python + QT for a desktop app?
Thanks in advance!
Can PyQty/PySide be used to develop really complex/modern UI?
Desktop applications come in all sorts of varieties -- some nicely laid out, some extremely customized with virtually no semblance to a standard application for that OS. The same can be done with Qt/PyQt/PySide. As Alex said, there should be no visible difference between an application written with PyQt/PySide versus one written with Qt in C++. Any program written with Qt4 (using bindings or not) will, by default, look like a standard modern application.
Of course, there are features of recent Windows releases (and likely some on Mac OS X) that aren't supported immediately and by default in Qt, but you can almost always write some custom platform specific code for those situations where said features are truly important.
Can somebody give me some points to have a look at some nice-looking screenshots of apps that are developed in Python+QT?
The best and most open source program that I know of and which is written with PyQt, is Eric -- a Python based IDE.
What about the performance of using Python + QT for a desktop app?
For most applications the performance difference between a C++ Qt application and a PyQt application are not noticible. But if you really need performance, you can write certain parts of the application in C++ and make bindings available in Python so you can integrate the two.
TortoiseHg was re-designed using Qt and PyQt for its 2.0 release.
Here is one of several posted screenshots:
There is no aesthetic difference between the look and feel of C++ based Qt, and the PyQt and PySide wrappers on top of it. I use basically no desktop GUI apps so I couldn't point you to any implemented with any of these language/toolkit combos, but if you like the former, you'll be hard put to distinguish it in any way from the latter.
A bit late but for the record, apps such as Skype, GoogleEarth or the recent versions of VLC (media player & more) used the Qt libs.
