Do you remember QML Book? It started as a project between me and Jürgen Bocklage-Ryannel where we tried to fix the problem that there is no QML book out there.
Back in the Qt 5.2 days, we spent wrote about a year. Unfortunately, the project has mainly been sitting idle since then. I’ve poked at issues every now and then, and Jürgen has done various fixes as well.
Thanks to The Qt Company, this is changing. This autumn, it sponsors me to work on the project. The current plan is to add a chapter to Qt Quick Controls 2, and to update the entire contents to Qt 5.12 and Qt Creator 4.8. By doing so, many of the remaining bug reports will be resolved.
Other things in the backlog are getting the CI system back into shape and having a native speaker edit the language. All in all, this will result in an up-to-date book on QML. If you want to help out, just reach out to me or send me your pull requests. All help is welcome!
