Hi Cris, You are right. The examples you provide are a bit hacky. The standard way in Roassal is to use composite shapes. Try this: -=-=-=-=-=-=-=-=-=-=-=-= v := RTView new. boxShape := RTBox new color: Color veryLightGray. labelShape := RTLabel new text: #name. composite := RTCompositeShape new. composite add: boxShape. composite add: labelShape. composite allOfSameSizeWithPadding. elements := composite elementsOn: (Collection withAllSubclasses copyFrom: 1 to: 5). v addAll: elements. elements when: TRMouseClick do: [ :evt | evt element model: Collection withAllSubclasses atRandom. evt element update. RTGridLayout on: elements. ]. RTGridLayout on: elements. v -=-=-=-=-=-=-=-=-=-=-=-= The code I provide defines a callback that changes the label. You can see how to adapt it. Let us know how it goes.

The boxes should grow or shrink horizontally so the text doesn't go outside the box. I saw the answer at http://forum.world.st/Roassal2-Label-width- td4847887.html which led me to a solution. However, I've commented the "not robust" part below, since it's passing by "lbl" which I suspect could change. ~~~~~~~~~~~~~~~~ | b label el | b := RTView new. el := RTBox new elementOn: 'hello world'. label := RTLabeled new center. b add: el. el @ label.

Maybe there's a simpler robust way?
