Nesting Builders in Roassal

by Evan Donahue

Hello, I am working with Roassal and trying to write a cell-layout builder that uses RTPieBuilders internally as its nested objects. The nesting docs cover nesting RT elements, but not builders. The composition docs cover composing builders, but not nesting them. I have a partial solution, but it is getting increasingly hacky, to the point where it may be easier to just duplicate the piebuilder code in my builder. Before I go down that road, I wanted to check if there was a more natural way to nest builders. Below is a mashup of the Roassal Examples Nesting and Pie Chart builders that gives the basic flavor of what I am trying to accomplish. Notice that I am creating new PieBuilders every time, running them, and extracting their createdElements for my layout. This works well enough, but if I then want to normalize global properties so that all pie slices with the same property get the same color, I have no way to coordinate the newly generated PieBuilders, as each possesses its own normalizer. Likewise, if I have a global PieBuilder, its internal state gets trampled with each iteration. I figured there was likely an easy way to compose builders that I didn't know about, so I thought I would ask. | v es b | v := RTView new. es := RTEllipse elementsOn: RTShape withAllSubclasses. v addAll: es. RTNest new for: es add: [ :group :model | b := RTPieBuilder new. b objects: RTShape withAllSubclasses. b slice: #numberOfMethods. b normalizer distinctColor. b view: v. b build. group addAll: b createdElements. ]. RTCellLayout new lineItemsCount: 8; on: es. v Thanks, Evan

Thanks Norbert for sharing the image. Ok, it seems I solved it: https://github.com/marianopeck/OSSubprocess/issues/17 Until I release a new version (and make gitfiletree use it), you will need to grab "master" (via the #baseline:) now instead of the stable release: Metacello new * baseline: 'OSSubprocess';* repository: 'github://marianopeck/OSSubprocess:master/repository'; load.

Mariano, I have the same thing in a freshly installed image. I couldn't say I can reproduce it at will but now it happened in two different images. Anything special I should look up?
