void lookupItemByItemTypeGroup(FormStringControl   lookupCtrl,
                                 ItemGroupId   ItemGroupId,ItemType _ItemTYpe=ItemType::BOM)
{
    SysTableLookup          sysTableLookup = SysTableLookup::newParameters(tableNum(InventTable), lookupCtrl);
    Query                   query = new Query();
    QueryBuildDataSource    queryBuildDataSource = query.addDataSource(tableNum(InventTable));
    QueryBuildRange         queryBuildRange = queryBuildDataSource.addRange(fieldNum(InventTable, ItemGroupId));
    QueryBuildRange         queryBuildRange1 = queryBuildDataSource.addRange(fieldNum(InventTable, ItemType));
     ;
    QueryBuildRange.value(ItemGroupId);
    QueryBuildRange1.value(enum2str(_ItemTYpe));

sysTableLookup.addLookupfield(fieldNum(InventTable, ItemId));
sysTableLookup.addLookupfield(fieldNum(InventTable, ItemName));

sysTableLookup.parmQuery(query);
sysTableLookup.performFormLookup();
}

edt lookup方法中调用

element.lookupItemByItemTypeGroup(this,'Lamps',ItemType::BOM);

--------------------------------

第二种方法

调用（调用方edt lookup）：

public void lookup()
{
    Args args = new Args();
    FormRun formRun;
    ;

    args = new Args(FormStr('Lookup_LookupForm'));
    formRun = classFactory.formRunClass(args);
    formRun.init() ;
    this.performFormLookup(formRun);

super();
}

lookup窗体只需覆盖closeSelect：（form属性Frame=Border）

public void closeSelect(str _selectString)
{
super(unit.unitid);
}
