You may have noticed that Qt is being ported to S60, and as you can read here, daily builds are available as technology preview since the end of September. At first, there are only MS Windows installers, but Lizardo did a great job collecting and writing patches and instructions to make it possible to develop with Qt for S60 on Linux.
To ease this process, I wrote a small script that does almost the same described in Lizardo’s post, with some new pseudo features. It needs some improvements, the known ones are marked with #XXX – contributions are welcome!
It consists in 2 files, the script and a config file where the user can customize the directories where things will be installed, the directory of the downloaded files, the version of S60 that will be used. Initially it’s ready for S60 3rd edition FP2 and S60 5th edition (Check here the version of your target device), etc.
Running the script, the first step shows the URLs to files you have to download, but need login or other kind of interaction with the website. The script is a nice guy, when it’s possible “he” asks if you allow him to open those URLs in your default browser =)
The script then downloads other files that are direct accessible and the installation begins. If everything goes right, in the end your environment will be ready for Qt-S60 development.
Welcome back dear readers. This is my second post of the day talking about what is happening in the development of animated layouts in Qt Kinetic.
As I said in my previous post, we discussed about new good examples that could show use cases of this new API. In the end, only one example was created, but it’s really cool =) .
Maybe some of you will recognize this interface, it looks like canola2’s main menu, another software developed by INdT for Nokia internet tablets (e.g. N810) -- and as you can read here, an old bug was fixed and canola2 is now a free software, released under GPLv3. In this post you can read more about the development of that interface.
So, we wrote an example based on that concept. During the development we had nice discussions regarding the algorithm for the engine that controls the icons distribution on the screen.
Check it out:

The source code is not available yet, but it will be published soon in a git repository near you, then you will be able to check how animated layouts were used and also see that algorithm I’ve just mentined. So, stay tuned!
A quick introduction: in the end of February I posted a video showing the first example of layouts animations. At that time, the API wasn’t complete and there was no integration with states and some stuff were hardcoded.
In March some Trolls visited Recife to speak at Bossa Conference 2009 (you can watch the presentations on http://openbossa.blip.tv). It was nice because we could talk about the work we’re doing together using whiteboards, what makes a huge difference =) .
After Bossa, we continued the development of the Animated Layouts API, making layout proxies transparent and integrating with the Qt State Machine Framework. It now allows the customization of animations per widget, bringing more flexibility in the creation of rich user interfaces using Qt.
The following video shows the old example with these improvements:

After that, we created some examples in order to show use cases and also to test what had been developed, but it is the next post’s subject! (remember what I said in the beginning? )
We are working together with Qt Software guys in the Qt Kinetic project, specifically with animated layout transitions.
Last week we made our first demo of what is being developed. It uses the basics we’ve just finished, now we’re working to define the final API. The following video shows this demo:
