The FormsBuilder is an algorithm for computing the position of a
matrix with several constraints on the columns and rows. As such you
can use it both to arrange the shapes in a complex shape, or to layout
the nodes in a graph.
In particular, the MOFormsBuilder>>asLayout can be used when the nodes
do not have the same height and width. Of course, if the nodes have
the same size, you can just layout them using regular layouts like
grid, vertical, horizontal.

a bit mysterious.
A table can be created using two different ways. Open an MOEasel and
doit:
This uses FormsBuilder.

or a more elaborated version:

view shape rectangle withoutBorder.
view nodes: (1 to: 5) forEach: [:each|
view shape rectangle withoutBorder.
view interaction forwarder.
view nodes: (1 to: 3) forEach: [:each2 |
view shape label.
view interaction forwarder.
view nodes: #('hello' 'world').
view horizontalLineLayout gapSize: 0.
].
view verticalLineLayout gapSize: 0.
]

A similar version with asLayout could be:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
| builder |
builder := MOFormsBuilder new.
builder column; column; row; row; row.
builder x: 1 y: 1 add: (view node: #notUsed forIt: [view shape
label. view node: 'hello']).
builder x: 2 y: 1 add: (view node: #notUsed forIt: [view shape
label. view node: 'hello']).
builder x: 1 y: 2 add: (view node: #notUsed forIt: [view shape
label. view node: 'hello']).
builder x: 2 y: 2 add: (view node: #notUsed forIt: [view shape
label. view node: 'hello']).
builder x: 1 y: 3 add: (view node: #notUsed forIt: [view shape
label. view node: 'hello']).
builder x: 2 y: 3 add: (view node: #notUsed forIt: [view shape
label. view node: 'hello']).
view layout: builder asLayout.

Note that these pieces of code are meant to be run in PhaMondrian

Tu pourrais m'expliquer succinctement le
principe du MOFormsBuilder
asLayout
J'essaie de construire une table avec mais je tatonne a partir des
exemples, c'est chiant.
