Last spring I started to write QuickFlickr application i.e. a Flickr client for N900. Back then I wrote this article of it. For me this is just a learning process to study QML and trying to figure out how I can write a real application using C++ for a lower layer and QML for the UI. The biggest challenge so far has been to design C++ side so that it provides usable interface to QML side. Before going too deep into details here’s the video about QuickFlickr running first on OS X and after that on N900.

QuickFlickr on N900
Sunday, August 15th, 2010My First Qt Quick App – QuickFlickr
Thursday, April 8th, 2010Some time ago I wrote how you can build and run QML applications on N900, but since that I haven’t done anything related to QML, until now. I’m not the only one at the moment who is trying to study how QML works and how you can deploy it in your application. I have always learned by doing, so therefore I decided to write a small application with QML.
I like to photograph and I have missed a good Flickr client for N900, so it was a natural choice to write a small Flickr client. I call it QuickFlickr, naturally:) So here’s the sneak preview of QuickFlickr. On the video I run it on Mac, because it takes too much time to build exactly the same version of Qt and Declarative module that I’m running on my laptop.
The application is far from ready and it lacks of proper graphics and bunch of functionality like uploading local images to the Flickr, but I will work on this app in order to learn more QML. I also managed to improve the performance quite much after I shot this screencast. I’ll add another video where you can see the performance improvement.
Do You Want to Donate N900 or/and a Laptop?
Sunday, February 14th, 2010You might have noticed that I don’t have any sponsors for my blog and I’d like to keep it that way. No adds and other commercial stuff can be found from my blog. IMHO is that adds are damn annoying. The exception can be that if I notice that some companies have done something interesting, I can promote it. Like I did with Uiemo video which is provided by Tieto. So this was just for your information that this blog is my personal blog and it’s not sponsored by any companies.
I like to test Qt related technologies on N900. It usually gives a good picture of the performance, but now I have a problem. There is only couple months left and then I need to send my borrowed N900 back to Nokia. Yes, I was also one of the lucky ones who had a chance to borrow the device for 6 months. I don’t want to pay almost 600 euros by myself and therefore I’m asking if someone wants to sponsor this blog and my work here by donating a N900.
Other thing that I would really need is a new laptop. I’d prefer to have MacBook Pro, but basically any laptop with enough processing power (dual core, 4G memory, NVidia Graphics card) would go. These two things would really help me to continue to with this blog.
So if you will donate N900 or a laptop, what will you get? I will write an article of the donations and mention you or your company name there. That’s it:) If you want to do a donation, please contact me first via email: marko.a.mattila(at)gmail.com. Thanks for reading my blog.
Qt/3D Running on N900
Friday, January 29th, 2010Qt Labs is the place where you can follow the direction of the Qt development. Of course it’s worth to follow the Qt Roadmap also. If you are interested in about what’s happening in Qt world, it is definitely worth to follow the Labs (in my opinion).
One of the most interesting projects at the moment is Qt/3D. As you might have noticed Qt doesn’t support 3D in painting when using QPainter, but now there is ongoing project called Qt/3D which brings this to Qt world. Instead of QPainter you can use QGLPainter for 3D drawing. There has been been possibility to use OpenGL before, but what Qt/3D brings is a Qt way to do that. Which is nice.
There are good blog posts about Qt/3D in Qt Labs blog section. So it doesn’t make sense for me to write more about this subject. You can check out the blog posts:
I decided to take a look at if it is possible to run Qt/3D applications on N900 and yes, it is possible. Below is a video where I run several Qt/3D demos on N900. The following demos are ran on the video:
- cubeaccel – A simple cube demo that reacts on device accelenometer values
- pageflip – A demo which models how to switch a newspaper page
- teapot – The classic 3D “Utah Teapot”
- planets – A demo which demonstrates the animation done with QSphericalAnimation
