4D v11 SQL allows developers to fill List Boxes with data from a Named Selection or the Current Selection.

Note that a new property has been added for the List Box object. The "Highlight Set" property is used to specify the name of the set that 4D will use to manage the selected rows of the List Box. You must specify a value for this property if you want the List Box rows to be selectable. If this object property is not filled in, and the List Box data comes from a selection, then the List Box rows will not be selectable.
