Re: [Pharo-users] Migrate code from Dolphin Smalltalk

by Esteban A. Maringolo

I solved it adding a few mock classes/methods, plus a bunch of regular expressions to convert Dolphin chunk to Pharo chunk. Dolphin uses methodsFor! and sets method category as a "do-it", while Pharo defines the category and the stamp in methodsFor:stamp:! It isn't super pretty, but got the job done. (I was able to file-in a lot of code I did years ago saving me from reinventing the wheel). Regards! Esteban A.

á§ And then, as if by magic, the problem vanished! I think the problem must have been something I was doing wrong at the Google end. Everything now works. Thanks Sven

Re: [Pharo-users] Roassal2 orthogonal lines, attach points and self-lines.

by Peter UhnÃ¡k

Hi Alex, I've refactored it a bit and created a RPControllable as a descendant of RTInteraction. You can see it in http://smalltalkhub.com/#!/~peteruhnak/RoassalPrototypes/ I also moved the >>resetShape method to Roassal's RTEdge as an extension package. But the way I reset the line remains quite daft. There's a simple usage example in RPControllable class side and a comment. Also there may be problems with the fact that I am basically hiding both shapes of the controlling elements and RTMultiLine. This could be solved with accessors, but my question is more conceptual - should the interaction be even responsible for creating those shapes - especially RTMultiLine? But than again RTLabelled creates Label itself too. Anyway... off to play with the grid now.
