Ohh! It is a fundamental problem for ROOT (and OO) to be solved! You
can realize that one CAN NOT SEE and "EDIT" the current value of any
current data-member (text and numerical) and change it via menu. Via
our popup menu one can see the class member-functions (no DATA) and
call it. The edit boxes of all menus are built from the list of the
parameters of those. Apparently "List of the parameters" is not
aware about the current state of the class data-members and present
it and let the user to change it too.
In fact it is not problem of ROOT (try "TObject::Inspect()"
function for instance) but the direct access to the class
data-member breaks the OO idea and can not be allowed.

No way to retrieve the current state of the TPaveText (and any
other object) and bring it into the menu.
Of course we are making the exceptions (see our FitPanel, DrawPanel
and so on). But ROOT Panels are the special things. it can not be
built "by automatic" from the user's include file so far. May be
we'll need the TextPanel too.

Ok, but this user's point of view must be DESCRIBED/defined
somehow. I think one of the way to solve is to build some sort of
View_of_Object ROOT C++ classes to reflect the particular point of
view of some user or group of users. It is assumed to be several
different views of one and the same "base" class. But it is just a
dream only at the moment.

Why not? And which WWW browser did you mean ? NetScape v.2.0 or
4.0, with Java or with no Java. May be you meant MS Internet Explorer
But again with ActiveX controls and a "pure" v.2.0.
If Java interpreter (virtual Java machine) can be a part of the WWW
client why C++ interpreter can not ?

*possibility* ? I know no thing one CAN NOT implement "in theory"
in his dream.
Yes sure the *possibility* does exist. The only question whether it
will be released, when and by whom?
