Re: red/yellow/blue buttons an anachronism?
by Ivan Tomek 01 Oct '99

01 Oct '99

I always tell my students to remember the 'word' RYB (red/yellow/blue) even though it doesn't mean anything, and it seems to work. I think that the current naming is acceptable and changing it might be confusing, but the proposed selectionButton, operateButton, windowButton would make sense - again assuming that the user is familiar with the use of the buttons.

AW: Java inside Smalltalk
by Torsten.Bergmann＠phaidros.com 01 Oct '99

01 Oct '99

The Smalltalk/X system from Claus Gittinger has a Smalltalk/Java integration. The system uses a dual interpreter to use Java The class hierarchy looks like the following: Object Behavior ClassDescription Class JavaClass java.lang.Object class Object JavaObject java.lang.Object ...(more Java classes) At this time he supports JDK1.1.x. With this integration he can debug, browse, inspect java objects in his Smalltalk tools and run Java applets in Smalltalk Windows, ... Native java calls are delegated to a special JavaVM class implementing the functionality in Smalltalk. To get more informations look at: http://www.exept.de/en/stja97.html Smalltalk/X also provides a STC (Smalltalk to C compiler). -Torsten

Java inside Smalltalk
by Martin Luptak 01 Oct '99

All discussions about Java and Smalltalk integration deal with running Smalltalk programs on Java VM, or translating ST programs into Java. What about idea putting Java into Smalltalk. Either Java VM running in Smalltalk, or encapsulation Java object into Smalltalk (they could live in one space - image, integrating their object models), or some other kinds of emulation/integration Java in ST environment. Doesn't someone know about projects concerning this?

red/yellow/blue buttons an anachronism?
by Robert M. Fuhrer 01 Oct '99

01 Oct '99

Hi All, This may sound silly, but... Is anyone else bothered by the apparently arbitrary use of "red/yellow/blue" to identify the mouse buttons in the source? I never remember which is which. Maybe it's because I go from Squeak on Mac to Linux to WinNT, or because I've never had an opportunity to work heads-down with the Smalltalk UI code to get it into my medulla, but it just doesn't work for me. So, is this an anachronism we can live without? I'd guess that cross-platform issues are part of the reason it hasn't been changed already (e.g. Macs use single mouse button + modifier key), so perhaps a set of more symbolic labels would work better, like (off the top of my head (or maybe that's the wrong end of the beast :^|)) "select"/"context"/"global". Or, perhaps the buttons should be relabeled pink/blue/black, to signify incremental improvement, paradigm shift, and no improvement whatsoever :-). -------------------------------- Robert M.

An image is a lonely place
by Tom Morgan 01 Oct '99

01 Oct '99

I've been noticing how lonesome it is inside an image. There are lots of strong place based/community elements which surround Squeak. These are currently formed by the basic networked apps of email, the discussion Swiki, the mail archives, and so on. There is now lots of machinery which is available which would allow basic collaborative support right inside a running image (and there are some spacey ones imagineable using the 3D stuff that feel like 'Snowcrash') The kinds of things that I have in mind revolve around establishing a sense of 'place', which is shared, 'embodiment' of you the user explicitly some how in the interface and some amount of 'awareness' of the presence of others in the shared place, all done with a light enough touch that we don't end up with avatar fashion shows. In this picture, an Morphic book wouldn't be found by reaching out across the network and loading it; instead, there'd be a more or less far away part of your image (maybe dressed up as an Alice world) that would let you wander around and find the book you wanted. Perahaps the author would hand it to you, if he happened to be around. While working, instead of the discussion Swiki, there'd be small knots of others, gathered around places of interest to them. You could glance around and see if anyone was nearby, possibly interested in what you were up to. Over the course of a few years, I have seen naive users comfortably navigate incredibly complex graph structures, when they are presented with a place based metaphor. I am not sure how universally appealing these interface metaphors are, but they seem to be captivating for at least some portion of the population. I remember one posting about trying to incorporate the ICQ protocols into Squeak. Are there others padding around this collaborative territory? ...Tom M
