OnGraphValueClick picture event

Declaration

Global handler:

 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.
