never tried to implement this... you would probably have to : use On Mouse down, and on mouse up, to get the coords of the dragged over area. then estimate/calculate how many lines were to be selected based on row height. Then use the listbox command to highlight those rows.
I might note that for any interface I have used where you can drag select, the software allows the drag 'drawing' of a selection 'square', which 4D list boxes do not natively support. I have not used it so I od not know how much work [probably a LOT] would be involved, but maybe rather then a list box, you might want to try SVG if you *must* implement a drag select interface.
