Thanks Colin, but I already visited that link before and although it explains some of the pieces involved, I don't see a coherent picture of how these things fit together -- it lacks context and a step-by-step approach.
It seems to me that this should be similar to the way Silverlight works, with the front-end XAML calling a client-side code-behind C# library. I'd imagine that the QML is the same as XAML and that it is coupled with some shared library where I'd write my C++. However, in the .NET environment I found the IDE made this pretty straightforward and I could also reference plenty of examples and tutorials. Sometimes you just need that one "noob" example to get something working end-eto-end and then you can easily tackle a really complicated case. Searching through the QML examples and demos that come with the source-build I see that under the "declarative" folder there's something called "minehunt" that looks very close to the mechanics of what I need to do. I guess I'll have to do some trial and error to see if I can mimic that, but I wish there was a guide for how to build something like that from scratch. QML looks very interesting and, like Silverlight/XAML, it's positioned well to do some very nice UI.

I'm pretty sure you'd need to call C++ code, unless Javascript has a way. Look here for calling C++ code in QML: http://qt.nokia.com/doc/4.7-snapshot/qtbinding.html#calling-c-+ methods-from-qml Colin --------------------------------------------------------------------------- This email and any files transmitted with it are confidential & proprietary to Systems and Software Enterprises, Inc.
