这个属性的设置如果不为零，那么你就不用通过拖动垂直滚动条去查看每个item了（但是你可能要用水平滚动条了，呵呵）详细 请看DELPHI的“官方说明书”----- help：Use Columns to specify the number of columns, in a multi-column list box, that are visible without having to use the horizontal scrollbar.Multi-column list boxes have a horizontal scrollbar that allows users to view multiple columns as they wrap. The default value for Columns is 0, meaning that the list box is not multi-column. That is, users can scroll only vertically and the list of items will not wrap.For Columns values greater than 0, multiple columns accommodate the items as they wrap beyond the bottom of the list box. The Columns property specifies the number of columns that are visible without having to horizontally scroll the list box.The width of each column depends upon both the Width property and the number of Columns.
