Re: [Pharo-users] Roassal2 Composite Shape

As far as contribution goes, I'd be happy to contribute but I'm still quite new to both Pharo and Smalltalk so I'm quite skeptical about the code quality. I've actually already made both shapes for rounded box but it will need some testing first; so I'll keep you posted. Peter Alexandre was always receptive of my rough contributions, and I learnt a lot about improving code quality from him. So I'd encourage you to give it a go. cheers -ben On Mon, Jul 14, 2014 at 10:47 PM, Alexandre Bergel <alexandre.ber...@me.com> wrote: Indeed, Roassal does not have a rectangle with rounded corner. Having it in Roassal means you need a new TRShape and a new RTShape. I could easily do the RTShape. But we need the TRShape first. Do you feel like doing it? This will be a valuable addition to Roassal.

However as I've mentioned in previous post I'm not sure about the rest of the shapes posted in the attachment. E.g. I haven't seen any notion of "box with rounded corners". I could compose it from four RTArc nad four RTLine but it seems to me overly complex compared to creating new Trachert/Roassal classes. The same would go for the other shapes. What are your thoughts/recommendations on that? Peter On Sun, Jul 13, 2014 at 3:25 PM, Alexandre Bergel <alexandre.ber...@me.com> wrote: Sorry, the version was not properly saved in SmalltalkHub. If you update Roassal2 and Trachel, you should be able to execute the code snippet I’ve sent you. Maybe you want to add “v open” at the end. If you are using GTInspector, this is not necessary. As far as I understand your description of the problem, you do not need to create your own shape. Let me know how it goes.

According to Monticello I have latest Roassal2 and yet I don't see RTMultiCompositeShape, but I would assume it should be what I was looking for originally. In the meantime I chose to do it manually - creating a custom shape in both Roassal and Trachert: I've done it in a single path because it seems that having multiple separate paths just creates more trouble. ======== computePath      canvas ifNil: [ ^ self ].      path := self athensCanvas              createPath: [ :builder |                      builder absolute.                      self ccwCirclePath: builder radius: 0.5. "building circular path with specified radius"                      self cwCirclePath: builder radius: 0.48.                      self ccwCirclePath: builder radius: 0.4 ] ======== But even if I could manage to do this with MultiCompositeShape I'm not sure about the rest of the shapes (see attachment).

I've tried using RTCompositeShape but that just expands the size of the smaller shape. Is there something else I'm missing (like fixing dimensions so they won't get updated) or should I subclass RTAbstractCompositeShape and try to make something on my own?
