Geometry Gridding
The setGrid attribute affects interactive resizing of the window containing the listbox. By default, a window can be resized to any size. If gridding is turned on, the size is restricted so that a whole number of lines and a whole number of average-width characters is displayed. Gridding affects the user feedback during an interactive resize. Without gridding the size is reported in pixel dimensions. When gridding is turned on, then the size is reported in grided units.
