Can anyone help me learn the 'modern' way of laying out morphs? I'm trying to create a stack-based ('RPN') calculate in Squeak (more as a way of learning the language and environment than because the world needs another calculator). I've been digging through 'Squeak: Open Personal Computing and Multimedia", which is a bit dated. The section on Morphic recommends using 'AlignmentMorph', but the comments for this class (in Squeak 3.10) suggest it is no longer needed.

 

So, what is the best way to layout a set of morphs? At least for now, all I need is a grid of buttons, that will look sensible when the parent calculator morph is resized.
