Hi Robert, 

Unfortunately, there is really no way around matching complicated data to
UI, unless you add a modelling layer.   That would give you other benefits
like saving and restoring data, but it takes at least as much code anyway.  

In our case we had 70 different exam questions, each with different data and
each requiring 2 dialogs.  We used separate classes for each with a
registration system and virtual methods to create, load, show, scrape and
save each dialog. 

We also used a designer plugin to add composite widgets for common data
groups across the question types.   This makes designing the UI much easier.


Hope that helps, 

Tony
