Videos convince me very easily!
I think we need a bit of discussion about the architecture for this approach,
especially to define a widget abstraction (maybe C++, maybe nasal) so dialog
authors can't break widget functionality unintentionally, but aside from that I
can't see many potential problems; Nasal can already process the GUI files
since they're property lists.
(I'm imagining a C++ factory function that takes a property node and builds a
widget - this would be exposed via a Nasal API - and even if it called back to
a Nasal definition for each widget type, would still allow us to build custom
widgets using the C++ canvas API if required)
The map-widget, route-manager waypoint list and airport-list widgets would need
some porting, but that's all pretty valuable anyway - especially for the
map-widget. As you say once it's done it would be re-usable for in-cockpit
displays which is all good. Since I created the Map-widget I've added a whole
bunch of Nasal APIs to query the navDB so that part of the map-widget is doable
without C++ now too.
Oh, and we need the option to keep the native menu-bar on Mac of course ;)
