Basic pageThe Qt Contributors Summit occurred June 10-11 in Berlin. Here is a quick summary of my impressions: 1) Unifying Qt Qt Project is highly interested in unifying Qt Commercial offerings with Qt Open Source. This was a major point made by Lars Knoll in his keynote speech and there were two…
BlogOne of the standard architectures of software systems is to have an application that talks to a server in some form. For example, a Qt application that talks to an Apache-based server with a REST interface. We see this with many of the applications we write for customers. The code in this blog…
BlogIntroduction When I first started using Qt in 2005, one of the classes that I found the most interesting was QDataStream. It was similar to something I had written many years earlier for standard C++ that performed a similar function but with iostreams. I wanted to cover enough aspects of this…

BlogThis week was a little slow as some people were away for the holidays. The new callback-qtimplementation by Viras got committed to github and we are now working with that version. Much of the week has been spent building Qt5. The source code for Qt5 is huge - several gigabytes. It takes…
BlogThis week was another slow week as many people were off part of the week due to New Year's or extended holidays. PhoneGap, recently renamed to Apache Callback, is now being renamed as Apache Cordova. There is discussion on the mailing list about where the code repositories will reside. It may…
BlogThis week we did some marketing to promote the project. I made a posting to the callback developer mailing list and we put a link to this blog from the ICS web site. Quim Gil of Nokia kindly made a posting to the Nokia Qt blog. I also recorded a podcast with Mark Hatch…
BlogThere was no blog posting last week because I was away for some vacation in a warm place. This week work continued implementing the APIs for Accelerometer and Notification and using the Qt Simulator for testing. We also started looking at the new APIs needed to use WebKit2 from Qt 5. With Qt 5…
BlogThis week we finished implementing some Cordova APIs (at least for the Qt 4 version). Compass and Accelerometer are done and some of Events was implemented. Notification is done as is most of File support and we are starting work on Contacts and Camera.Note that I am going to start consistently…

BlogSince the last posting we properly set up deployment of Cordova Qt for MeeGo Harmattan (e.g. the Nokia N9 phone). We also got Qt 5 packages including WebKit built for MeeGo Harmattan and tested it on a Nokia N9. Incidently, a big PR1.2 software update rolled out this week for MeeGo Harmattan phones…
