If this attribute is omitted and no child items are specified then the control is empty. If both this attribute and child items are specified then the child items are ignored.
getItemLabel : An ST_Delegate attribute that specifies the name of a callback function which is called to determine the labels of dynamically created selection items in this control. If this attribute is omitted, dynamically created selection items do not display labels.
getItemScreentip : An ST_Delegate attribute that specifies the name of a callback function which is called to determine the tooltips of dynamically created selection items in this control. If this attribute is omitted, dynamically created selection items do not display tooltips.
getItemSupertip : An ST_Delegate attribute that specifies the name of a callback function which is called to determine the Enhanced ScreenTips of dynamically created selection items in this control. If this attribute is omitted, dynamically created selection items do not display Enhanced ScreenTips.
