Template Class and QML

St.Stanislav

Hello all!
I did some steps in my investigations, but have faces with several problems (some of them I solved, some moved me to another way). But I have decided to wonder, about possibility of my idea. Can I create template class that can be used in QML?

What I have tried:

I inherited from QPair<T, P> and create my own

structure Range<T>: public QPair<T, T> {}

I have defined constructors, inner logic and so on. I have also registered my type with qRegisterMetaType for some specific template class, e.g. Range<quint32>. Everything looked like OK, but in QML all methods of Range were inaccessible (returned undefined value, e.g.). So I have tried to register it additionally with qmlRegisterType and found that staticMetaObject is not Range<quint32> member. As far I understand that's because of my Range type is not QObject (correct my if I wrong).

Obviously, my second attempt was creating my Range as QObject derived class, but I faced big problem much more earlier: QObject does not support template.

So my question is: can I create my own template class that can be used in QML? For my example above I wanted to use my own methods

T lower() const {return QPair<T, T>::first;}
T upper() const {return QPart<T, T>::second;}
