 ; 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.
