Combobox change events

Combobox change events

Postby DonDrew » Fri Mar 25, 2011 3:17 pm

I'm having a problem controlling the behavior of a combobox change event response.

Every time I update the array of list items, oClaim_Num:SetItems( aClaims ), the change event response is triggered. Is there any way I can restrict the change response to user input only?

Code: Select all  Expand view
bChange:=oDbCombo:bChange
oDbCombo:bChange:=NIL
oDbCombo:SetItems(aMyNewArray)
oDbCombo:bChange:=bChange

Regretably that didn't change anything.

Thanks for your help.

Don,

If you do this do you hear a beep?

oCombo:bChange:=msgbeep()
oCombo:SetItems(aMyNewArray)
oCombo:bChange:=nil

It should be

Code: Select all  Expand view
oCombo:bChange:={ || msgbeep() }

Hello... you can try this change in the class

Code: Select all  Expand view

   METHOD Reset( lChanged ) INLINE Eval( ::bSetGet,;                                                    
                         If( ValType( Eval( ::bSetGet ) ) == "N", 0, "" ) ),;                            
                         ::nAt := 0, ::SendMsg( CB_RESETCONTENT ),;                                      
                         if( ( lChanged != NIL .and. lChanged ) .or. ( lChanged == NIL ), ::Change(), )  


   METHOD SetItems( aItems, lChanged ) INLINE ::Reset( lChanged ), ::aItems := aItems,;
                                    ::Default(),;
                                    if( ( lChanged != NIL .and. lChanged ) .or. ( lChanged == NIL ), ::Change(), )

 


use oClaim_Num:SetItems( aClaims, .F. )
