[Qt-qml] QML without GUI?

[Jason H]

Exactly. And I am studying Wt now...
I still think they could use a QML version.

Qt already has this capability :) I would agree with Alan though, the 
Right Way to do this is via a component set adapted to that particular 
domain. It's only wrong if you go for the HTML syntax renderer *only*. 
As I toyed with this idea myself, I can say that I see the real 
work/benefit coming from making the session handling transparent and if 
your component set supports the get/post/ajax interaction model. What 
you get that way is that HTML really becomes just a UI layer and you can 
keep your logic and data models on the C++ side. Of course, to make it 
usable your application itself has to be made concurrent-multiuser 
(which is not the case for most classic QML/desktop applications), but 
that's a different story (see Wt). Doing the UI in a HTML-oriented 
component set is IMHO a *lot* better than what the already mentioned Wt 
does with its WWidgets.
