ENTRY OnGraphValueClick(IN INT _refId, IN INT _LineNr, IN FLOAT _value, IN INT _mouseBtn)
; script action
END OnGraphValueClick
Special handler:
ENTRY XXX_OnGraphValueClick(IN INT _LineNr, IN FLOAT _value, IN INT _mouseBtn)
; script action
END XXX_OnGraphValueClick
Parameters
_refId
Required input parameter of INT type for global event 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.
_value
Value which user click on.
_mouseBtn
Number of mouse button.
Description
The picture event is generated by clicking on value of
graphic flow placed in the graph area and only when the graphic flow is
configured as interactive and the Pointer is disabled.
Example
Special picture event handler:
; picture event handler: clicking on value of graphic flow
; of Graph type, to which the reference variable _GRAPH is assigned
ENTRY GRAPH_OnGraphValueClick(IN INT _LineNr,IN FLOAT _value, IN INT _mouseBtn)
; script action
END GRAPH_OnGraphValueClick
Global picture event handler:
; picture event handler: clicking on value of graphic flow in displayer of Graph type, that has no special picture event handler defined
ENTRY OnGraphValueClick(IN INT _refId, IN INT _LineNr, IN FLOAT _value, IN INT _mouseBtn)
; _refId - value of reference local variable of picture,
; that is assigned to graphic object
IF _refId = _GRAPH THEN ; test that checks the displayer where the picture event occurred
; script actions
ENDIF
END OnGraphValueClick
Note
If both, special and global handlers, are defined in script,
the global one will never be called because the special handler is already
defined.
