You can do that, but only indirectly. You cannot make a template class 
that direcly inherits and extends QObject. However, you can make a 
template class that inherits a class that inherits and extends QObject. 
Basicaly the only thing you cannot do with that construction is have 
signals and slots depend on your template parameter. Note that you can 
also make the class the template inherits from a template argument 
itself, so you really have quite a few options to work with. Still, 
_sometimes_ it would be _nice_ if it would just work directly. However, 
you probably shouldn't need it much, and it is not that hard to work
