[Moose-dev] Re: [Roassal 2] updating CompositeShape

Hi Jan, Composite shapes could be a nasty beast. This is a part of Roassal for which I am not even sure of which semantics if should have. So, we may end-up in some corner, as you have explained. However, we are luck here: this is a easy problem to solve. The modification you wish to have, which is changing the label has to be done directly on the trachel shape and _not_ the roassal shape. Consider this slightly modified version of the script: -=-=-=-=-=-=-=-=-=-=-=-= compo := RTCompositeShape new. compo add: (RTEllipse new size: [ :tupple | tupple third ]; color: Color lightBlue). compo add: (RTEllipse new size: [ :tupple | tupple second ]; color: Color blue). compo add: (RTLabel new text: [ :tupple | tupple first ]; color: Color red). "ADDED LINE to demonstrate it does not keep this layout: " compo vertical. v := RTView new. data := {{ 'hello' . 30 . 50 } . { 'World' . 20 . 70} }. v addAll: (compo elementsOn: data). RTHorizontalLineLayout new alignCenter; on: v elements. v elements @ RTDraggable. "ADDED LINE where I change labels text:" v elements do: [ :elem | |label| label := elem trachelShape shapes third. label text: 'LABEL'. ]. v -=-=-=-=-=-=-=-=-=-=-=-= And just to make my email more entertaining, here is the screenshot: Alexandre
