Hungry for grid docs - Ext JS

I have a hard time figuring out how to use undocumented classes, and grid requires many classes- few of them with any formal documentation. OK it's alpha and it's to be expected!

Specifically, my data is in an array, has the first column as a numeric ID which should be hidden. I'm reading the source and have figured out that in this portion:

new Ext.data.ArrayReader({id: 0}, [  {name: 'my_id', type: ...},

the "{id: 0}" says that the row id is in column 0. The second part has one object per column with its attributes.

My real question --> What are the choices for "type"? What are the other config options? <--

The ID should stay hidden. I figure that's a config option in Ext.grid.ColumnModel called "hidden", found it in the source. Semi-rhetorical question: why are the grid source files divided into two directories, source/grid and source/widgets/grid?

I suppose none of this is all that important, I'll slog though it now, and later the docs will be done and it won't be an issue.

To answer my own q (more or less): the "types" of a field are defined in source/data/DataField.js not specifying a type will set it to auto and uses the field as-is valid values for type are: string int float bool (or boolean) date (if given, can also specify dateFormat) Some other config options are: defaultValue mapping sortType sortDir (defaults to ASC) I haven't investigated the source further, now that I have the info I'm looking for.

Next grid-related question, does RowSelectionModel have a config option to specify only one row selected at a time, disabling shift-click/drag/etc? My quick look through the source tells me "no".

My quick look through the source tells me "no". var grid = new Ext.grid.Grid('grid', { ds : ds, cm : cm, selModel : new Ext.grid.RowSelectionModel({ singleSelect : true}) }
