[nebula-dev] Checked Tree Items ?

[Charlie Kelly <Eclipse@xxxxxxxxxxxxxxxx>]

I'd like to create a tree column in a Grid with checked items that is
similar to the one displayed to the Grid home page 
(http://www.eclipse.org/nebula/widgets/grid/grid.php).

I can't find the source code for this display.

How do I create items that are checked (as opposed to a column with a 
check box) ?

How do I set and retrieve the value of the check(s) ?

Thank you

Charlie
