OnItemSelect picture event

Declaration

Global handler:

 ENTRY OnItemSelect(IN INT _refId)
 ; script actions
 END OnItemSelect

Special handler:

 ENTRY XXX_OnItemSelect
 ; script actions
 END XXX_OnItemSelect

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 when the user changes currently selected line of Windows control of List box type or displayer of Browser type.

Example

Special picture event handler:

; picture event handler: Change of selected line in the list
 ; with reference variable_List assigned

ENTRY List_OnItemSelect

  ; script actions
 END List_OnItemSelect

Global picture event handler:

; picture events handler: Change of selected line in all lists and

; displayers of Browser type that have no special handler defined

ENTRY OnItemSelect(IN INT _refId)

; _refId - value of Reference local variable assigned to graphic object
   IF _refId = _List THEN ; test that determines where selected line was changed
    ; script actions

  ENDIF
 END OnItemSelect

Note

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