That's what the recommendation has been: develop one desktop UI and one mobile 
UI. The two have very different UX needs, including mouse/touch differences but 
also the ability to follow the native look-and-feel of the target platform.

The QtWidgets library we've been using for desktop was designed in the 
mid-1990s and does not fit the model for mobile UIs (it can't do animations 
very well, for example). It has not been and will not be updated to work on 
mobile UIs.

So if we want a mobile UI, the recommended way by the Qt Project is to use Qt 
Quick Components.

That's not to say a complete reimplementation. For one thing, there is a way 
to insert some of the existing QPainter-based widgets, like the graph in the 
dive profile. For another, the long-term recommendation by the Qt Project is to 
design our desktop UI with Qt Quick Components too, which is not something 
we're ready to do just yet.
