Use this event to update Items property for the particular function. Function is defined by the list of names in FuncNames parameter where 0 index is the last name. 

For example, in function: 

StcControls.StcController(scLeft).PutItem(.... 

FuncNames[0] = "PutItem" 

FuncNames[1] = "StcController" 

FuncNames[2] = "StcControls" 

OnGetParamsEx is called only when defined FuncNameRule and FuncPathRule properties. These properties define how to get names of sequential functions.
