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.
