Thinking about what you have said. Host windows. Mmm... I don't disagree
with you about the immersive environment of squeak managing the windows.
I am thinking that TruffleSqueak would make a good window manager. I
think you could use Java Swing to build your host windows. Is it so?
Good for production apps. Get the tree lists right and you should be
good to go.
I would rather see Professional Spec widgets, that look & feel like host
widgets, but managed inside Squeak. A step back from the dynamism of
Morphic. With all the animation and graphics work and sound/speech, I
don't see why host look & feel could not be hosted within Squeak. Of
course, all OS styles should be configurable, so on Windows you could
switch to Mac windows or Ubuntu look&feel. The issue is time. I wholly
Is that how a squeak display is used? I am unfamiliar. But that sounds
like a window manager to me! Multiple Displays. Now this proposal of
yours to use a Project for each Display, seems to interleave with my
proposed ERights Vat and event loop. I was thinking whether each window
event loop could feed the Vat event loop. The Vat's event loop already
comes in as priority 40 or 30, so very background. Like a bubbling
spring, I like to think. A Project sounds like a good boundary, to me.
I believe each Project can establish its own naming environment. Is it so?
I am very interested in forming a Secure DNS, with hierarchical naming
and local caching. I want to use it as an interface registry, as well,
such that the ASN1 structure definitions are so shared. ASN1Modules are
kinda hierarchical, but not completely. For example, I do not think I
implemented any way to search up and down the tree, for a definition. I
have further thoughts on auto deploying consumers for the various event
structures, that may appear unexpectedly, so the engine would dyno-load
the consumer package registered for that event type.
Closer to my heart, at this point are my questions and request for help
in splitting off a pruned stack for an exception, to unblock the event
loop yet still allow introspection of an error, or a halt. Here is what
I wrote. Tim, might you be able to advise me here? *lost*

I've been having to use VW a bit recently (see recent email whining about the awful font stuff) and I really, really, don't like having separate host windows. I think part of the problem is that I tend to have a *lot* of windows open and it turns out that none of the current main OS (yes, I've been using Windows, Mac & various unix) handle lots of windows at all well. It's much easier to have my Squeak world nicely tied together.

Instead of trying to make every host window a separate Squeak window, make each a Display and then it you want to spread a couple across several physical display, go for it. Maybe hanging it all off the idea of Projects would be a good start? A Project window already gathers groups of windows after all.
