OnClick picture event

Declaration
Global handler: 
 ENTRY OnClick(IN INT _refId)
 ; script actions
 END OnClick

Special handler: 
 ENTRY XXX_OnClick
  ;   script actions
 END XXX_OnClick

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 by left-clicking the graphic object (for Windows control of Tab control type, the picture event is being generated when switching between tabs. The picture event is also generated when given tab was removed (made invisible) using the function HI_SetVisible (actually, the user selected another tab) - there is generated the picture vent for the first visible tab from the left.

Windows controls of List box and Spin button types do not generate the picture event and therefore the special handler is not allowed for them.
Example
Special picture event handler:
 
; picture event handler: Clicking the graphic object
 ; with reference variable_BtnOK assigned
ENTRY BtnOK_OnClick
   %HI_ClosePicture() ; closing picture
 END BtnOK_OnClick

 
Global picture event handler:
 
; picture events handler: Clicking on graphic objects
 ; that has no special handler defined
ENTRY OnClick(IN  INT _refId)
; _refId - value of reference local variable assigned to graphic object
   IF _refId = _BtnOK THEN ; test, that determines the graphic object
                           ; the user clicked on
     %HI_ClosePicture()    ; closing picture
   ENDIF
 END OnClick

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