Rectangle packing

There is a new layout for packing rectangle nodes.

Gofer new
   smalltalkhubUser: '' project: 'RoassalAlgorithm';
   package: 'Roassal-New';
   load

---------------------------------------------------------------------------------------------------

"Source code: ROMondrianExample>>miniMapOn:"
"Preambule. It includes the initialization. "
| view rawView |
rawView := ROView new.
view := ROMondrianViewBuilder view: rawView.
"-------------"
"-------------"

   view shape rectangle
       width: [ :cls | cls numberOfVariables * 5 ];
       height: #numberOfMethods;
       color: (Color r: 0 g: 1 b: 1 ).

   view nodes: Collection withAllSubclasses.

   "1 to: view nodes size by: 2 do: [ :ea ||i e| e := view nodes at: ea.
                                                       i := e width.
                                                       e width: e height.
                                                       e height: i.
                                                       e extent: e width @ e height ] ."

   view layout:(( RORectanglePacking new)ratioWidth: 2 height: 1; padding: 3).

"-------------"
"-------------"
"Below is the initiation of the menu and opening the visualization"
ROEaselMorphic new populateMenuOn: view.

Re: Rectangle packing

In reply to this post by MathieuDehouck

I guess the correct incantation to load the code is

Gofer it
smalltalkhubUser: 'MathieuDehouck' project: 'RoassalAlgorithm';
package: 'Roassal-New';
load.

A screenshot:

Can you comments the methods?

#ratioWidth:height:

#padding:

This is a very compact layout. Excellent!

Cheers,

Alexandre

Yes :)
What would be good is to be able to say that the largest nodes can be
computed using log: so that we can control that we are not completely dependent
of the large node.
