OnColumnClick picture event


Declaration
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
_refIdParameter of the INT type (required for global handler).
XXXName 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.
