Qt Symbian Fonts - qt

I have created a Qt app for the Nokia Ovi store but I know want to update the font int the QML file, but just changing it in the designer doesn't change it on the symbian device. I have checked google but nothing I can find looks right. If it helps the font I want to use is Kristen ITC but it might change.


If you want to use a custom font, you'll need to deploy that font along with your application. This blog article should help you out, though I don't use Symbian so perhaps another answer can go into more detail.
Once font is available on the device, you'll need to add it to your application using QFontDatabase::addApplicationFont.
You'll also want to look into licensing whichever custom fonts you deploy with your app. Kristen ITC, for example, is included with Microsoft products, but licensed by the Monotype Corporation.

how is Wunderlist source code protected?

I am trying to build a simple app using tidesdk , but unfortunately as stated here :
https://stackoverflow.com/a/14207566/1724929
that currently there is no way to protect the source code which is visible to the app users.
but after taking a look at wunderlist for Windows which is built using tidesdk and .net framework , i saw that the source code is not visible also i searched if it were hidden somewhere but i found nothing , so any one have an idea how they protect the source code from being visible . is there any tool or something to achive that ?

Latest version of Wunderlist is not built using TideSDK. They have re-implemented all different versions pure natively on each platform they are supporting.
TideSDK currently does not support Code hiding however the Developers of TideSDK are developing TideKit which is releasing soon with a new CLI, app and will provide platform builds. It will also provide Code Hiding. You can follow recent developments at http://www.tidekit.com. The video of what is coming is here: http://youtu.be/aE7gN-d0GhU. This will give you modern tools to use where the experience of creating and your projects is much better.

Qt Under LGPL: How to distribute changes to Qt source code?

We've developed a commercial Qt application with Qt under LGPL. We link dynamically. We also made a few changes to a couple of files in Qt to better suit our needs. I realize that according to LGPL, I must make those changes publicly available.
My question is how is that done?
Do I set a webpage on my domain with the modified source codes available for download?
Do I distribute the modified source code in a folder on the client target machine after installation?
Another
way?

You simply have to make them available on request.
It can be a file on your web server, it could just be emailing them to anyone that asks, you can even supply them on floppy disk and make a charge for it.
Ideally you would also contribute the changes back to Qt if it's a bug fix or feature that could be useful to other people, then it may be incorporated in future editions and youcould then just use the standard build.
ps. The letter of the GPL says that you have to provide everything that is needed to create your modified build - so the full Qt sources and the build files. However for a large complex project like Qt, if you have only modified a couple of files it would be useful to offer a download of just these (or even a diff against the specific Qt version)

According to the licence you need to provide your changes back to the community, not just to your customer.
The easiest way is forking the main Qt repository on http://qt.gitorious.org/qt and commit your changes there.

How to adjust sound of QWebView based Qt Application

I have created a Qt GUI application which has QWebView object to open a URL which has embedded flash content. My problem is that I would like to control the audio volume of my Qt Application(QWebView), but I am not able to find any way to do so.
However I came across classes from the Phonon module like AudioOutput and VolumeSlider but had no luck.
There is one example on the Qt website but that itself uses Media Player, for which we can control the volume.
Please advise on how can we get rid of this problem.
It looks like this is a limitation of QWebView based application as of now.

The problem is that Flash manages it's own volume and you cannot access it from Qt.

How to use Nokia Qt to launch another mobile application within an application based upon a MIME type?

I am using Qt Nokia for mobile development (I'm currently testing on a Nokia C7) and would like to launch an application from another an application based upon a MIME type.
For example, I might have a file, and I would like to be able to open another application from the original application without specifying the application but using the MIME type of that file. On the other application opening it would load the file and perhaps be given an additional message or payload.
If this sounds a little strange it might help to know that I have come from a J2ME background and would have used the CHAPI API.
I need to use Qt Nokia so that I can build the application for the Symbian or Maemo platform. So far I have only been able to find documentation showing you how to do it under Symbian.
Can I do what I require by using Qt Nokia? I am just not looking the right places?

QDesktop::openUrl may be a good candidate.
This HowTo may be helpful.

Flex/Openlaslzo for RIAs?

I recently stumbled upon flex/openlaszlo (OL). Both seem very useful and I have a few questions about them:
What is needed to deploy flex apps? From what I understand, the flex sdk
is open source, but the other tools
(for development and deployment) are
proprietary.
What is needed to deploy openlaszlo? Is it completely open
source (from development to
deployment), or does it have
development/deployment "gotchas" like
flex?
Specifically, I'd like to use flex or openlaszlo to either augment or
replace an editable table I created
using js, ajax, html, and css. Is this
the type of thing flex/OL can/should
be used for? Are there any drawbacks
or pitfalls to using flex/OL for this
rather than straight js, ajax, html,
css?
Thanks.
Edit: Are there any licensing (use) restrictions on applications built on flex? i.e. applications built on flex can be for only non-commercial use, unless a commercial license is purchased?

The following link has some discussion about openlaszlo and flex, it may help you:
Use the best open source client-side framework for cloud computing

You do not need anything special to deploy Flex apps. Just put the compile app (a SWF file) on any web server. Flex apps can talk to any back-end.

Flex SDK is free, but Flex Builder is not. You can use the free and open source FlashDevelop to write flex apps - it doesn't have drag-n-drop features like flex builder, but it offers code hinting and stuff. I don't know about openlaszlo.

Below is the link providing details of tools/IDEs for developing OpenLazlo applications
http://wiki.openlaszlo.org/Development_Tools

Re: "What is needed to deploy openlaszlo? Is it completely open source (from development to deployment)"
OpenLaszlo is OpenSource, but the typical versions you install come with the main components pre-compiled into a SWF for the SWF run-time. However, you can download the full source code if you wish to look at it and/or compile the core yourself:
Last official released version (4.9.0): http://download.openlaszlo.org/4.9.0/openlaszlo-4.9.0-src.tar.gz
Nightly builds:
http://download.openlaszlo.org/nightly/trunk/ (you will see "source" as an option after you click the link of the version you want)
OpenLaszlo does not require anything else to be deployed but itself, except if your application is compiled to the SWF run-time then the user will need the Adobe Flash player installed in their browser to use it.

I'll answer your last question: the biggest drawback to using Flex is that it requires the client to have the Flash Player plugin installed in their browser. Not that big a deal for most people since Flash Player is over 98% of all computers. With the straight Javascript, AJAX, HTML, CSS approach it should work on all browsers, assuming you wrote it correctly.
