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.

Personally, I also find MOFormsBuilder>>asLayout a bit mysterious. A table can be created using two different ways. Open an MOEasel and doit:

This uses FormsBuilder.

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= view nodes: (1 to: 5) forEach: [:each| view nodes: (1 to: 3) forEach: [:each2 | view shape label. view nodes: #('hello' 'world'). view horizontalLineLayout. ]. view verticalLineLayout. ] -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

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.
