[Gnumed-devel] re uml for programmers

[s j tan]

It had a good example (not working though) where you defined the
interface ( bodiless method signatures) of a user interface, and then
the interface 
of a model class. Then the person who writes the model knows how he's
going to get called and how to get data from the user interface, and the
user interface can attach the mutator methods to its widgets' ( python
speaks) set methods , and can call the models list accessor or validator
methods.
If the the interface is sufficient , a new ui can be written later with
a different look but the same interface, and same with the model /
domain linking class.
