[Moose-dev] Roassal - idea for compound shapes

I think the following would be the start of a good example of how Roassal works... | view rawView el1 el2 edge line | rawView := ROView new. el1 := ROElement new. el1 extent: 50@50. el1 + ROBox red + ROCircle yellow + ROLabel @ RODraggable. rawView add: el1. rawView open ...except that it would be nice if the ROLabel could be centred. In addition, being able to place the ROLabel in various "offset" locations, I think that would satisfy a lot of my composition requirements - for example building a transformer compound symbol with two overlapping circles and two labels for "equipment tag" and "power size". To that effect it would be great if ROLabel or similar could have a callback mechanism to get different attributes from the model. Alternatively I guess I could make a new subclass of ROShape that draws such that directly. cheers -ben
