创建一个List获取数据的lookup

第一步，在类：syslookup中新建方法

public static client void lookupList(FormStringControl _formStringControl, List _valueList, str _columnLabel = '')
{
Args    args;
FormRun formRun;
;

if (_formStringControl && _valueList && _valueList.typeId() == Types::String)
{
    args = new Args(formstr(ScanWorkX_Lookup));
    args.parmObject(_valueList);
    args.parm(_columnLabel);
    formRun = classFactory.formRunClass(args);
    _formStringControl.performFormLookup(formRun);
}
}

 

第二步

public void lookup()
{
List    valueList = new List(Types::String);
;

...build your valueList here...

MyClass::lookupList(this, valueList, "List Title");

super();
}
