EAS BOS 用代码设置query实现界面的排序

/** * query排序 */protected void beforeExcutQuery(EntityViewInfo arg0) {SorterItemCollection sorterItems = arg0.getSorter();SorterItemInfo sorterItem = null;if (sorterItems != null && sorterItems.size() == 0) {sorterItem = new SorterItemInfo(tblMain.getColumn("PurchaseOrg.name").getFieldName());sorterItem.setSortType(SortType.ASCEND);sorterItems.add(sorterItem);sorterItem = new SorterItemInfo(tblMain.getColumn("FixCenter.name").getFieldName());sorterItem.setSortType(SortType.ASCEND);sorterItems.add(sorterItem);sorterItem = new SorterItemInfo(tblMain.getColumn("number").getFieldName());sorterItem.setSortType(SortType.DESCEND);sorterItems.add(sorterItem);}super.beforeExcutQuery(arg0);}
