We haven't blogged here for some time, in part because many of the folks at ICS have been very busy planning and preparing for the annual Qt Developer Days conferences in Berlin, Germany and Santa Clara, California. We had some coverage of the Raspberry Pi and Qt at the recent... Continue reading

I thought it would be a good time to step back and review where we are on the Cordova Qt project, as it may not be obvious just from glancing at the Wiki. Software The source code is maintained in the Apache git repository at git-wip-us.apache.org as well as a... Continue reading

You do need to be familiar enough with Qt and C++ to build the Cordova for Qt code and build packages to submit to an app store, if applicable for your platform. Right now that is probably too much to expect from a JavaScript developer. We're planning to do some work soon to better integrate with the Qt Creator IDE so this should be much easier for a non Qt/C++ programmer to use, i.e. you would run a new project wizard and should only need to add your html and Javascript code.

We've recently been running the Cordova tests and making some fixes to get them to run better. We've documented on the Wiki how to run the Cordova tests. See the section "Running Cordova Tests" at this wiki page. We hope to have a demo video up soon showing the tests... Continue reading

Thanks for trying it out and reporting these issues. We'll definitely take a look and address them and/or document them if they are problems we can't currently resolve.

Work has been slowing down somewhat as Qt 5 has been firming up for release. The Qt 5 alpha came out on April 3rd and we tested our code with it. Work is moving ahead for a Qt 5 beta release and then the 5.0.0 final this summer. Qt 4.8.1... Continue reading

There is now a short video up showing it running with a Nokia N9 with Qt 4: http://www.youtube.com/watch?v=U_ay0U5FIts I'll collect some info how to get started with PhoneGap for Qt and put that in a future blog posting and on the Wiki.

Throughout this project one thing that has been constantly changing has been the source code repositories, both due to several project names changes and with the move to being run as an Apache project. This last week the old repository at http://github.com/cordova/cordova-qt was removed and replaced by the read-only repository... Continue reading

Since 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... Continue reading
