OnSpin picture event

Declaration

Global handler:

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

Special handler:

 ENTRY XXX_OnSpin
 ; script actions
 END XXX_OnSpin

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 clicks on the Windows control of Spin button type.

Example

Special picture event handler:

; picture event handler: Clicking the spin button
 ; with reference _Spin assigned

ENTRY Spin_OnSpin

  ; script actions
 END Spin_OnSpin

Global picture event handler:

; picture events handler: Clicking a spin button

; with no special handler defined

ENTRY OnSpin(IN INT _refId)

; _refId - value of reference local variable assigned to graphic object
   IF _refId = _Spin THEN  ; test that determines the spin button
                           ; the user clicked on
    ; script actions

  ENDIF
 END  OnSpin

Note

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