Where are they saying this, and about what language? Is it Self itself? Very interested in your reply, Jerry Archibald systemObjectivesIncorporated

Ian probably knows more about the contents of Mario's Ph.D. thesis than I do; from memory, it was a formal description of several O-O languages, of which Smalltalk was completely specified.

RE: [ENH] improved drop
by Pennell, David 04 Nov '99

Thanks!!! You just made my "To Do" list shorter. Now if we can get it to carry the morph relative to the cursor point at original button down time... It sometimes takes FreeCell a little while to decide if a card (or stack of cards) can be dragged. The cursor and the dragged card(s) can get pretty far apart. -david > -----Original Message----- > From: Sean McGrath [mailto:sean@rosewood.his.ucsf.EDU] > Sent: Wednesday, November 03, 1999 6:17 PM > To: squeak(a)cs.uiuc.edu > Subject: [ENH] improved drop > > > Here is a change (to HandMorph dropTargetFor:event:) that > uses the center > of the dragged morph instead of the cursor position to find > the target of > a drop.

RE: [ENH] Desktop Menu

Or is there a third option? I find both styles appropriate. If my morph encapsulates an independent application (like FreeCell), I prefer to run it in a SystemWindow. You can quickly collapse it when you want to look busy :>) If I want to embed it in another Morph (e.g. BookMorph), I leave it bare. I think some may be working with bare morphs because of the "Add a new morph" menu. I remember my first trip into Morphic Land and it took a little digging to find the right protocol for opening one directly. I recently added "openInWindow" and its relatives to Morph to make it easier to open any single Morph in a SystemWindow. -david

Faith of Correspondents? (was re: GUSI 2 Released (info for Squeak Sockets))

Eh, just a question on the rim of the subject - what is the status of Correspondents in regard to inclusion in official Squeak? I have just looked briefly on this framework but it sounds very interesting and I might also be interested to base a project on it. But a few questions arise: 1. As it seems you have implemented a new Streaming framework which is simply "better" than the existing stuff - has SC said anything about incorporating it in Squeak? 2. The exceptionstuff, if I am not mistaken, got rejected in favour of a framework from 4th Estate (correct?) - is this a problem? Do you regard your framework to be "better" in some respects and if so, could that stuff be merged into the 4th Estate framework? Can Correspondents easily be adapted to the official exception framework? 3. Is there, in your own opinion, any arguments for NOT including Correspondents in official Squeak? These questions may be infested with factual mistakes - if so, correct me. :-) regards, Gran ===== Gran Hultgren, gohu(a)rocketmail.com, icq#:6136722 GSM: +46 709 472152, http://195.22.65.4 "First they ignore you.

--551687059-25946-941671027=:252 Content-Type: TEXT/PLAIN; charset=US-ASCII Here is a change (to HandMorph dropTargetFor:event:) that uses the center of the dragged morph instead of the cursor position to find the target of a drop. When dropping large morphs, like playing cards, it works much better because system behaviour matches visual expectation when the cursor is near the edge of the morph you are dropping.

[BUG][Fix] CustomMenu class documentation
by Mark Guzdial 03 Nov '99

03 Nov '99

There's a pretty severe class documentation error for CustomMenu. It's the only menu class that documents the pieces of building menus, but it says to use invoke/invoke: to open the menu, instead of the correct startUp/startUp:.

ssh/linux/X windows -- a slow combo
by Lyn A Headley 03 Nov '99

03 Nov '99

I've got squeak 2.6 running on redhat linux 6.0. I would like to connect to the linux machine from another Unix box via ssh, run squeak on the linux box and use X Windows to display it locally. This works fine, but I'm finding the graphics far too slow. Does anyone know any tips for speeding up X in combination with squeak and ssh? -Lyn
