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.
Thanks in advance,
Mike

Just use AlignmentMorph.
I don't understand any of the comments about it being deprecated. AlignmentMorph is still used throughout the image and works well enough.

TableLayout is your friend here. The class comment gives some hints. A week or so ago there was a discussion about Morphic table layouts, there you can find hints where to get grid layouts.
In general you can send a Morph layoutPolicy: TableLayout new
I suggest you create a Morph, add a TableLayout like above, bring up the halo, the red button offers layout.
There you can experiment and see the options you have.
If you don't look into the thread in Squeak dev, beware TableLayout is no real table layout but a row or column layout.

Building a Calculator was done as tutorial.....
Check http://wiki.squeak.org/squeak/5791
Sorry I don't have time to complete the "bad english" version, bud some pictures in original work sure was enough for smart newbies.
And AligmentMorph is long, long , long time obsolete and no project using it should born in XXI century.
