I am developing an application for Nokia Symbian since last two months, Nokia is a new platform for me I have good experience in iPhone development, I started Qt SDK 1.0 what I found 1.0 was not really good for some mobile device specially in UI, I just moved out to Qt SDK 1.1 released on 1st March 2011 I went through QML (Qt Quick) I found it really good in UI experience, finally when I reach to OVi for publishing my application OVi just refused my application due to Qt SDK 1.1 which is not supported on Nokia Symbian devices yet.
Again I cam back to Qt SDK 1.0 I used QDelearativeView and used same QML structure its working fine on simulator but when I am trying to build it for Symbian device I am getting error "no such file or directory".
Now I have number of questions listed below
1 - How can I fix this error and publish it to OVi
2 - Any good resource for publishing & signed process for Symbian devices
3 - Any expectation how much long Ovi would take to support Qt SDK 1.1
Thanks in advance,
Mohammad Asif
Qt SDK 1.0 contains Qt 4.6.3 which doesn't support QtDeclarative. SDK 1.1 Beta contains Qt 4.7.2. That's the reason for compilation error.
According to this, you could build your app on SDK 1.1 Beta, package it with the currently available Qt Smart Installer and submit it. Though it will only be deployed to store once Qt 4.7 based Smart Installer is available.
For Ovi Store related questions I suggest you consult Forum Nokia's Publishing to Ovi Store forum.

I have already created Qt based application which uses some third-party open source library like OpenCV, I have looked Windows Dev Center and seems the all the reference is using Visual Studios and other Windows tool. I have created my App using Qt creator. Is it possible to submit such an application on Windows App store?
Any help will be appreciated,
Thanks

Bad news: Microsoft does not support Win32 apps on AppStore yet (but it has been announced, currently under development as "Project Centennial"). It looks like an "old-school" desktop applications cannot be submitted to the Windows App store.
Good news: Qt has support for WinRT (complete in Qt 5.6 which is currently in Beta and will be released in a few weeks). And qmake can generate a Visual Studio solution from your project (in case you need it for deployment or debugging; VS Community edition is free).
Qt WinRT tutorial: http://doc.qt.io/qt-5/winrt-support.html

I was looking at the Qt 5.6 feature list, and it claims 'Full Windows 10 support'. Now I'm wondering, does this mean that ALL Qt features are supported on Windows 10 by the release of Qt 5.6? I'm asking this because I really want to use QtBluetooth on Windows 10, but Qt is not clear about the support of that on Windows 10.
Can someone clarify things up?
In Qt 5.5 Qt Bluetooth was supported for the following platforms:
Android, iOS, Linux (BlueZ 4.x/5.x) and OS X
Then in 2015 Qt developers discussed Bluetooth for Windows, see blog
Hopefully, we can close the gap towards the last major platform which is not yet supported. A WinRT port is being planned for Qt 5.6
But in Qt 5.6 there are no new features related to Qt Bluetooth and in tracker we see that:
WinRT (classic and Low Energy) is scheduled for Qt 5.7.
So this is not a question of Win10 support, I guess Qt Bluetooth will remain for the same platforms in Qt 5.6 and will be ported for Windows later.
I am curious about the qt version used on Blackberry 10 momemtics IDE. Can I use QT5 for blackberry 10 development ?
Directly from the documentation you can find here.
The current release of the BlackBerry 10 Gold NDK
[developer.blackberry.com] includes Qt 4.8 for both the simulator
target (x86) and device targets (arm) available for development.
Compared to the development for the PlayBook, Qt is integrated in the
BlackBerry 10 device firmware and so can be used by Qt applications as
shared libraries.
The page is quite detailed. Have a look at it.
However, Qt5 can still be considered. You can find more information on how to use this Qt version in this other page, which states:
Currently, Qt5 is neither included in the BlackBerry 10 device
software nor in the BlackBerry 10 SDK. However, Qt5 on BlackBerry 10
has reached a excellent level of quality and can be used for
developing and publishing applications to BlackBerry World.
BlackBerry 10 supplies only Qt 4 libraries.
You can use Qt 5 as long as you bundle your application with self-built Qt libraries.
Here you can find detailed information.
The number of mobile operating systems or platforms supporting QT based app development keeps growing. Not for all of them QT is the standard framework for building apps, therefore it seems the Qt support can be categorized as follows:
Qt and Qt based technologies (QML, QtQuick, QtMobility) are the recommended way for building mobile apps and part of the SDK.
Qt or a subset of Qt is supported as a secondary way of developing or porting apps, and there is support for a subset of QT APIs within the SDK.
Unofficial 3rd party or open source extensions enable development of Qt based apps for a platform.
Which mobile operating systems or SDKs do support development of apps using Qt in either of the above listed ways?
Mobile operating systems with full Qt support in the SDK:
Nokia Symbian OS: http://www.developer.nokia.com/Develop/Qt/. Since Nokia discontinued Symbian, Qt for Symbian is a community effort now.
Nokia N9 / MeeGo 1.2 Harmattan: Full Qt support.
Mer (community Meego fork) and Sailfish OS: Qt/QML are both supported.
Canonical's Ubuntu Phone uses the Ubuntu QML toolkit and Qt Creator for native application development.
Mobile operating systems supporting a subset of the QT APIs:
Blackberry 10 OS and SDK: The Blackberry 10 SDK contains the Cascades UI framework, which is built on top of a subset of Qt 4.8 and QtMobility modules. Apps can be created using Qt, QtMobility and QML/QtQuick. Another approach is porting an existing Qt application that uses QtGui.
Digia, community driven (open source) and 3rd party extensions targeting mobile operating systems:
Android: QT 5 port by Digia (demoed at Qt Developer Days Berlin in Nov 2012), expected to be released by the end of 2013.
iOS: QtQuick 1.0 port by Digia (demoed by Qt Developer Days Berlin in Nov 2012), expected to be released by the end of 2013.
WinRT / Windows 8: (demoed by Qt Developer Days Berlin in Nov 2012) demo.
Qt for Android port Necessitas: Has been donated to the Qt project in Nov 2012.
Qt SDK for iOS devices by Mediator Software: The product website does not contain much information, but there are regular updates on Twitter Qt4iOS (links to apps in Appstore built using QT SDK for iOS are posted on Twitter).
From QtCreator I chose Mobile Gui Application and did not change a line of code. I built it using simulator and it works fine. When I try to deploy it on to my device I get a warning
'Application not compatible with Phone. Continue anyway.?' Obviously the app is not working on my device.
I have installed Nokia Qt SDK 1.1 and have installed Qt 4.7.3 ( including QtMobility and QtWebKit ) which comes with the SDK on to my device.
What am I doing wrong?
Thanks
Maybe this thread on forum nokia solves your issue. Which device do you have?
