Qt has basic support for compressing and uncompressing data with its qCompress and qUncompress methods. Although those methods use the same compression algorithms that are used in zip files, they do not produce proper archives. Those methods can be useful if you want to exchange some date between two Qt applications, or maybe store some compressed data that will be read only by Qt applications. In all other situations, you have to look for some library that can handle proper zip files.

In case you are working on an application targeted for Symbian phones, one of the easiest ways to work with zip files is to simply use existing APIs available on Symbian OS. This is a short blog post that will show you how to use those APIs from your Qt application. Read more

This post is actually about a bug that I ran into while developing a mobile application using Qt 4.6.3. The bug can cause a Qt widget to take up a size that is larger than the screen area available for the application, which means that a part of the application is rendered outside of the screen. I spent a lot of time searching for a workaround for this bug, but was unable to find anything useful. In the end, I decided to try to devise a workaround by myself.

To spare you the time, there is no way to integrate Facebook in a WRT widget at the moment and I don’t see it becoming possible at all. Now, let me share with you some obstacles which we stumbled upon and what solutions we have come up with while trying to add Facebook functionality to a WRT widget.

As you probably know, Nokia WRT environment is targeted at web developers familiar with HTML/CSS/Javascript set of technologies who should be able to utilize that knowledge in creating mobile apps. Very neat idea, not so well implemented though, but that might be a topic of another post.

Ovi, the Finnish word for door, is one of the simplest words in the Nokias home country language. It expresses Nokia’s vision to become the consumers door to the Web. The general goal for Ovi is to offer a single location where users can manage content, services and people they encounter as they’re surfing the Web. That’s definetly a bold goal considering the heavy competition such as Google, Microsoft and Apple they are inevitably encountering in this area.

Ovi Store is the Ovi segment intended to provide users with all kinds of downloadable content such as games, application, music, ringtones etc. Publishing to the store is open to everyone and costs the developer a one-time entry price of 50€ which is about 65$. To compare, entry price for Apple’s App Store is 99$/year and for Google’s Android Market its one-time 25$.
