How to programmatically draw in Flex 3?

I was surprised by the lack of documentation( and working example) for this simple task.

Here's what I've got so far:

  • Flex doesn't like "Shape" objects? replace them with "UIcomponent"
  • a "UI component" must be attached to a container (like a canvas, a panel,...)
  • the shape will be visible when it is added has a child of the container: myCanvas.addChild(myCircle)
Here's an example with 3 buttons (1 to create a rectangle, 1 to create a circle, 1 to move them appart):

Run (right click at runtime then "view source" to see the code):
