Global handler:
?
ENTRY   OnColumnClick(IN INT _refId, IN INT _column)
; script actions
END    OnColumnClick

Special handler:
?
ENTRY XXX_OnColumnClick(IN INT _column)
; script actions
END XXX_OnColumnClick

Parameters
_refId Parameter of INT type (required for global handler).
XXX Name of Reference variable connected to graphic object (without the character "_").

Description
The picture event is being generated if the user left-clicks the column header in displayer of Browser type. The parameter _column is the serial number of the columns.
Example
Special picture event handler:

 
?
; picture event handler: Left-clicking the column header
?
; in displayer of Bowser type with reference variable _List assigned
?
ENTRY List_OnColumnClick
?
; script actions
END List_OnColumnClick

 

Global picture event handler:


 
?
; picture events handler: Left-clicking the column header
?
; in the displayers of Browser type that has no
?
; special picture event handler defined
?
ENTRY OnColumnClick(IN  INT _refId, IN  INT _column)
?
; _refId - value of reference local variable assigned to graphic object
   IF _refId = _List THEN ; test that determines the Browser, the picture event occurred
?
; script actions
?
ENDIF
END OncolumnClick

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