Just posted for fellow M206 sufferers a short HOWTO do M206 diagrams in Squeak. "It's CRC, Jim, but not as we know it".

It's at

http://www.penguin-home.telinco.co.uk/M206_diagrams

Of course, if you want to do do drawings with things connected with lines, you could do worse than to get my Connectors stuff and use it.

It already has UML diagram elements, and will work with any Morph you want to make. And there's even a button for saving images! It does arbitrary line endpoints, as well, which is nice for your filled circles.

I did a quickie ButtonBar with your diagram elements in less than 5 minutes, and saved it as a project.

You can get the Connectors stuff from Bob's Super Swiki, and then load the project from: http://nedkonz.dhs.org:8080/Ned/12

and you'll have a customized editor.

Ned, thank you so much! This stuff is excellent, even by your standards. I'll re-do my page right away!

Cheers

I can read in the connectors project from BSS, but when I try to load http://nedkonz.dhs.org:8080/Ned/uploads/12/M206.pr

I get a message asking me how to convert ncButtonBar (from memory) to a "modern class".

Here's the method it asks me to fill in nCButtonBarbosfcebb0

I'm at 3.2alpha #4599

By the way, what is M206? Some school class, or is it something more august?

P.S. Thanks for the tip on EventRecorder; it saved putting a lot of work into something that wouldn't work.

Ned probably answered the first part of the question off list (from memory, it's important to use a late version of the connectors stuff, but Ned's answer should be regarded as far more likely to be correct than mine!).

M206 is an undergrad course run by the Open University (UK based, but available pretty much anywhere) which uses Learning Works (a "teaching" Smalltalk based, IIRC on an early (3.1 ish?) Visual Works) to teach OO programming. I don't think I'm entirely alone in thinking that they should use Squeak instead and adopt Mark Guzdial's book as the main text.

Cheers
