That's how I got started coding as well. :-)   One BIG thing to note is Qt does the heavy lifting for you between JS and C++: If you use properties and signals/slots, it becomes trivial. In your C++ class declare a Q_PROPERTY and use the getters setters.  Q_PROPERTY( name ... ) In your QML clas

Re: [Interest] Can QML model specify a range including negative numbers? For example -180 to +180 ?

If it's a sequential model you can: 1. Add the interval number as the model, and subtract the number you want. model: 360 *Then:* model -= 180 2. Create a javascript function to fill it: function makeList(model){ for (var x=-180; x <= 180; x++) { model.append({"value":x}); }}

Re: [Interest] Can QML model specify a range including negative numbers? For example -180 to +180 ?

You'd better provide your implementation of TumblerColumn component. Despite that fact, and assuming you somehow manage to know what value was chosen, I'd suggest (as a quick attempt) to set model: 361, and the shift values by -181. On Wed, Nov 4, 2015 at 5:53 PM, Edward Sutton wrote: > Is ther
