Questions about QML for new developer

[kyleplattner]

We are looking into using QML to develop a UI for a linux embedded display unit and I had a few related questions.

1. Are there any books or other resources that I can get my hands on that lay out QML well?
2. How can I create my own QML widgets?
3. How would one begin to approach GPS mapping?

Thanks,

Kyle

I don't know any book yet about Qt 4.7. Let's see if any other colleague can help on this. A starting point is the "official documentation":http://doc.trolltech.com/4.7/qtquick.html, not ideal yet IMO but enough to begin.

There is this "topic":http://doc.trolltech.com/4.7/custom-types.html in the docs about creating custom QML elements. For more complext widgets, probably you'll need to write parts of it in C++, then check "this tutorial":http://doc.trolltech.com/4.7/qml-extending-tutorial-index.html.

Take a look at Qt-Mobility Location API, "docs here":http://doc.qt.nokia.com/qtmobility-1.1.0-beta2/location-overview.html.

I hope these answers help you somehow. I don't know how familiar you are with Qt and its docs, so maybe I wrote a lot of 'already known' stuff.

KDAB is offering two trainings about "Qt Quick for C++ Developers" in the near future, assuming you have some C++ skills already, this may be what you need. The dates are January 25-26, 2011, in Berlin, Germany, and February 08-09 in Houston, Texas, USA. Please see the "full schedule":http://kdab.com/index.php?option=com_content&view=article&id=65&Itemid=78. We can also run this training (even customized to your needs) onsite for your team at pretty much any time.

There was a great presentation on mixing C++ and QML at the "DevDays":http://qt.nokia.com/qtdevdays2010/. Maybe you can still make it to the San Francisco event?

The presentations were recorded, I have no idea when those videos will become available though.
