Dear Rene

I am sorry, but I cannot resist to make a comment, too:
When I was searching for a framework for my own project in 1999,
I was considering KDE/QT before I discovered ROOT which fitted
my intentions perfectly and which in general I consider to
be the best C++ framework for many reasons.

I was also very delighted to see that ROOT offers its own
architecture-independent GUI classes. Only after already
extensive use of the TGClasses I realized that these classes
suffer from the 32k limit which e.g. prevents the creation of
large tables. This is really sad but I understand that the
GUI development has a lower priority within ROOT development.

I am still reluctant to switch to QT for many reasons, one
reason being that I prefer to work with only one framework,
and I hope that this limitation will be eliminated soon.
Since ROOT was created to deal with very large data sets
it would be great if there would also be a possibility to
display/select large amounts of data within the GUI.

Is there a timeframe within which the 32k problem will be

Best regards
C.h.r.i.s.t.i.a.n. .S.t.r.a.t.o.w.a
V.i.e.n.n.a.         .A.u.s.t.r.i.a
