To do drag&drop IndentingListItemMorph asks some 'complexContents' in its #mouseDown: method for #canBeDragged:; but in my Image only two classes implement this message and only ListItemWrapper answers true. But ListItemWrapper isn't used anywhere in my image, therefore my question: Do you use this d&d functionality? Do you know of any other use of this d&d functionality? Would be nice to have something to play with... BTW: Have you taken a look at my ExtEventHandler? Regards, Stephan

One of the best collection of pointers for this stuff is the 'Non-Linear Magnification Homepage' at http://www.cs.indiana.edu/~tkeahey/research/nlm/nlm.html It coveres a lot of useful stuff about many different aspects (including fisheye techniques). Incidentally, it's hard to believe that hyperbolic trees are patented per se - the math has been there before and even the projections (AFAIK). And there are plenty of approaches that have similar properties (just check out the refs from above) so that it should be easy to come up with a sufficiently distinctive technique that's not covered by patents. - Andreas PS. Here's one idea - how about using Quaternion space?! Has a couple of cute properties... (there are probably more reasonable approaches but why bother?! ;-) > -----Original Message----- > From: Henrik Gedenryd [mailto:Henrik.Gedenryd@lucs.lu.se] > Sent: Tuesday, March 28, 2000 10:44 PM > To: squeak(a)cs.uiuc.edu > Cc: recipient list not shown > Subject: Re: zoomable morph? > > > Torsten.Bergmann(a)phaidros.com wrote: > > > An interesting representation for trees is Hyperbolic Tree > > http://www3.inxight.com/htdbdemo/htdocs/index.html > > > > It's patented :( > > > > Torsten > > > > There are also Fisheye views, original reference in > Proceedings of CHI 86-87 > something (George Furnas wrote it I believe).

If someone is willing to dive into the VisualWorks code and port it to squeak we could surely find it on some backup ;-) michael -- "To improve is to change, to be perfect is to change often."

[BUG][FIX?] PluggableTextMorph>>accept
by Stephan Rudlof 29 Mar '00

29 Mar '00

Nasty bug! Difficult to find for me... :( "Change Set: Fix_PluggableTextMorph>>accept Date: 29 March 2000 Author: Stephan Rudlof Dan changed the line [self setText: textToAccept shallowCopy. to [self setText: self getText. ; probably to save time. It this was his goal, reverting to the previous version given here should be correct. If he had another intention there is needed more thinking...
