Example

Special picture event handler:

; picture event handler: clicking the user button in

; the displayer of Graph type with reference variable GRAPH assigned

ENTRY GRAPH_OnGraphBtnClick(IN INT _LineNr)

  ; actions
 END GRAPH_OnGraphBtnClick

Global picture event handler:

; picture events handler: Clicking the user button in displayers of Graph type

; that have no special picture event handler defined

ENTRY OnGraphBtnClick (IN INT _refId, IN INT _LineNr)

; _refId - value of reference variable that assigned graphic object
   IF _refId = _GRAPH THEN ; test that checks the displayer, where the picture event occurred

; actions

  ENDIF
 END OnGraphBtnClick

Note

If both the handlers are defined in picture script, global handler will never be called for _refId=_List, because the special handler is already defined.
