Ah, now I see the confusion. Part of the reason my messages get so
long is I try to clarify things as much as I can to avoid confusion,
but here I see I didn't explain what I meant by "programming
I meant what I'm doing now, dropping components onto a form to build
the view of an application. When no component exists that does what I
want, I subclass something as close as I can find, add the behaviors
it needs then move back to the designer and drop the new component
onto the form. Of course the view only generates events or method
calls, one has to write code to actually do something with it.
And I think this is how most what I have been calling "graphical
developing systems" have worked (including Squeak-Morphic, even if it
has proven the most difficult to get started in), but what has been
missing in all the systems I had previously looked at was this ability
for these components to be extendable and first class. Creating a
semi-complex layout for a form, then "inheriting" that form to create
other forms and factor the common behavior into the base forms. I.e.,
OO programming but in the graphical designer as well as the

Ah ok. In that case I would agree. As Paul Graham said "a lot of the
best ones were languages designed for their own authors to use, and a
lot of the worst ones were designed for other people to use." .
And this idea holds for designing systems as well no doubt. My point
was just that one also must balance this with practicality. Make it
for yourself, but make it so *you* can do real world common things
with it as well as anything your mind can imagine.

"killer feature". Can't believe I typoed that. :)

Well, my presumption here was that the piano and the chart were
already created as separate components (as appears to be the case in
Morphic). If so, it would indeed be trivial to add them to a form and
slap together those menus. Of course you have to write the code that
wires it together, and C# isn't a concise language, but I would expect
it to be none-the-less straight forward once one has those two complex

Simple: Smalltalk is a superior language and superior environment.
It is only this one aspect that is currently more intuitive in C# and
that is fixable. What I'm trying to understand is how big is the gap.

I suspect I will port certain features of it, though Smalltalk being a
truly live environment removes the need for some of C#s more

But the chart-like morph is a stand alone morph that views on an
envelope using a variation of the standard MVC, no? In this case, I
would expect it to behave exactly the same, though it will obviously
be more lines of code in C#. But the hard part is in defining the
Envelope viewer, not in putting it on the form or wiring it up.

I don't actually have much hope on "visual programming" as in "build
everything graphically and write no code what so ever".
A picture is worth a thousand words, but the book is always better
then the movie. I see programming more like a book/movie then a
static picture. But I also am a strong believer in DSLs, and for me a
graphical designer is the DSL if you will for low level uninteresting
details about how components are laid out on a display. So I want to
do with my "graphical" DSL what I can do with my "textual" DSL:
extend it to be more powerful and factor common patterns into the DSL.

Now that I know what you mean, I agree. :)
