Hi Stef, I think the example that Alex provided is less advisable and it is misleading :). Itâs indeed interesting that you can do what he shows, but I do not think this is the example that people should see first. I got my hands on an image. Here is an example that is composing two elements: element := BlElement new layoutStrategy: BlBasicLayoutStrategy new; shape: (BlShape new path: BlRectanglePath new; strokePaint: (BlStrokePaint new paint: Color blue; width: 4)); extent: 500@500; position: 0@0; addChild: (BlElement new shape: (BlShape new path: BlCirclePath new; fillPaint: Color red); extent: 450@450; position: 25@25). element openInWorld. Is this what you had in mind? Cheers, Doru

How to make square element with filled circle inside:
1) Subclass BlElement -> BlCell 2) Override drawOnSpartaCanvas: aCanvas super drawOnSpartaCanvas: aCanvas. aCanvas setShape: self localBounds; setStrokePaint: Color blue; stroke
3) Override initialize to have circle shape: initialize super initialize. self shapeDo: [ :aShape | aShape path: BlCirclePath new; fillPaint: Color red ]. 4) Open cell in word
Easy :)
Except that I do not understand it. I do not understand why I should do setShape: self localBounds;
and why I should do shapeDo: in the initialize
This is totally unclear to me. So this means that I cannot program anything I want with it. Imagine I could not find anything simpler than a box with a circle drawn on it and even with the solution I cannot understand it.
You see in Morphic this is simple: you have a drawOn: aCanvas method and you know how to draw: aCanvas I do not get the interaction between the draw and the initialize. This is totally unclear.
Now I tried and this code did not work in the build 26 so I tried with drawOnAthensCanvas: and it crashed. So I stop. No need to reply to this email and thread.
