I think you got my point, namely, that in 1995 there was no such thing as Qt, GTK, Wx, and probably not Swing either - ah well, those were the days of FVWM or MWM and Motif :-)

Most computer science concepts are 30+ years old :-)

To me, it's appealing - think GRID :-) ROOT's solution is to use ACLic to do a `pseudo' `code-once, run-everywhere'. Not necessarily a bad solution.

I'm not that familiar with ObjC, but it looks sort of OK. Then again, some people - like the US DOD - swears on Ada.

Uh, they must have changed it. It used to say that, isn't that right Fons and Rene? Perhaps it's back to basics: `ROOT's the rOOt of everyThing' :-) I'm sure some people will hate that one :-)
