Hi Stef,
I think the example that Alex provided is less advisable and it is misleading
:). It’s 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
