If you open up a Squeak image, select Open.. SqueakMap Catalog, you should see in the list Classbox and ClassboxBrowser. The code appears to date back to 2005/2004, but should be available to load and try out.<div><br></div>
<div>Note that I haven't done this - you may (or may not) need an older version of Squeak to get this code working.</div><div><br></div><div>Thanks,</div><div>-Chris</div><div class="gmail_extra"><br><br><div class="gmail_quote">

For a project on university I've read the paper "Classboxes: Controlling<br>
Visibility of Class<br>
Extensions" by Alexandre Bergel, Stéphane Ducasse, Oscar Nierstrasz and Roel<br>
Wuyts (<a href="http://scg.unibe.ch/research/classboxes" target="_blank">http://scg.unibe.ch/research/classboxes</a>). Now I would like to test<br>
some examples with classboxes in Squeak. Therefore I was looking for the<br>
implementation, but I could not find a download link (only some dead links<br>
like <a href="http://www.iam.unibe.ch/~scg/Research/Classboxes/classbox.zip" target="_blank">http://www.iam.unibe.ch/~scg/Research/Classboxes/classbox.zip</a>). Is<br>
there a possibilty to get the code or a squeak image with included code for<br>
classboxes?<br>
