ENTRY OnGraphBtnClick(IN INT _refId, IN INT _LineNr)
; script actions
END OnGraphBtnClick
Special handler:
ENTRY XXX_OnGraphBtnClick(IN INT _LineNr)
; script actions
END XXX_OnGraphBtnClick
Parameters
_refId
Required input parameter of INT type for global handler.
XXX
Name of the reference variable assigned to graphic object (without the character "_").
_LineNr
Serial number of the graphic flow, the button of which was pressed.
Description
The picture event is being generated when clicking given user button placed in the graph area.
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.
