这是场景:我正在使用需要分组的列表网格,并且还需要在每个组中对其记录进行排序。我已经使用了ListGrid.sort()
和ListGrid.sort(String, SortDirection)
方法,但它们都不能正常工作。
当网格未分组时,此问题不会出现(它使排序完美);当通过单击列标题进行排序(将listgrid分组)时,工作正常,但我需要通过代码对其进行排序(无需用户交互),因为需要禁用标题排序选项(以及上下文菜单)。
我正在使用 SmartGWT 4.0
这是我正在使用的课程:
public class Access extends ListGrid {
public Access() {
super();
setWidth("30%");
setHeight100();
// setShowHeaderContextMenu(false);
setCanResizeFields(false);
// setCanSort(false);
setAutoFitWidthApproach(AutoFitWidthApproach.BOTH);
setWrapCells(true);
setFixedRecordHeights(false);
setShowRecordComponents(true);
setShowRecordComponentsByCell(true);
ListGridField id = new ListGridField("id", "ID");
ListGridField user = new ListGridField("user", "User");
ListGridField access = new ListGridField("access", "Access");
id.setHidden(true);
user.setWidth("60%");
access.setWidth("40%");
access.setType(ListGridFieldType.BOOLEAN);
access.setCanEdit(true);
setFields(id, user, access);
groupBy("access");
access.setGroupTitleRenderer(new GroupTitleRenderer() {
public String getGroupTitle(Object groupValue, GroupNode groupNode, ListGridField field, String fieldName,
ListGrid grid) {
return (String) groupValue + " - " + groupNode.getGroupMembers().length;
}
});
getField("access").setGroupValueFunction(new GroupValueFunction() {
public Object getGroupValue(Object value, ListGridRecord record, ListGridField field, String fieldName,
ListGrid grid) {
Boolean access = (Boolean) value;
if (access)
return "With access";
else
return "Without access";
}
});
ListGridRecord lgr1 = new ListGridRecord();
lgr1.setAttribute("id", 1);
lgr1.setAttribute("user", "ewgzx");
lgr1.setAttribute("access", true);

setRecords(new ListGridRecord[] { lgr1, lgr2, lgr3, lgr4, lgr5, lgr6, lgr7, lgr8, lgr9, lgr10 });
