That way there are only two actors, the morph and its owner, and a morph knows (based on two messages, whether it should maintain its relative place and size within its owner. Although I have got a bit of the hang of layoutMorphs, I’m exploring whether positioning and repositioning a lot of elements in my UI may be easier with this approach.

Hari,

I think we all need to get more experience building things to see what works and is as simple as we can make it.

Please continue to build things and share them!

Here is the example using aLayoutMorpk and a LayoutSpec.

"
    self example2.
"	| f g |
	g := LayoutMorph initializedInstance openInWorld.
	g padding: 0.5. "center"
	f := RectangleLikeMorph new.
	g morphExtent:400 at 400; color: Color orange.
	g addMorph: f layoutSpec: (LayoutSpec proportionalWidth: 0.25 proportionalHeight: 0.25).
 	f morphPosition:150 at 150; color: Color blue.
	g morphPosition:70 at 70.
