Most obviously so, I think. Isn't that the whole idea of the og system?
In fact, I find it so convenient to not have to drag data and other
information around these days that I have given up on State structures
in the ad-hoc widget programs. The entire /NO_COPY business becomes
unnecessary once you make your State an object, since it is persistent
in the heap memory and fairly static.
I definitely agree that object widgets is the way to go but I write
little new code these days, and some small improvements like State
objects do simplify the classic widget development.
We are inevidably coming back to the same old question of objects'
self-awareness, in other words, being able to pass information on an
object to other objects, preferably without having to explicitly specify
their IDs as parameters in routine calls.
Cheers,
Pavel
