Hi Everyone,
I need help here , I'm trying to check if the node is scrolled off or
not by doing this , but the State always come back focus and selectable.
The node in my case is HTML List Box
nsCOMPtr<nsIAccessibleRetrieval> cpAccRetrieval=
do_GetService("@mozilla.org/accessibleRetrieval;1");
if( nsnull != cpAccRetrieval )
{
nsCOMPtr<nsIAccessible> cpNodeAccessible = nsnull;
cpAccRetrieval->GetAccessibleFor( cpDomNode ,
getter_AddRefs(
cpNodeAccessible ) );
if ( nsnull != cpNodeAccessible)
{
PRUint32 state =
nsIAccessibleStates::STATE_UNAVAILABLE;
PRUint32 Extstate =
nsIAccessibleStates::STATE_UNAVAILABLE;
cpNodeAccessible->GetFinalState(
&state,&Extstate );
if ( (nsIAccessibleStates::STATE_OFFSCREEN &
state ) )
{
ZEROCLASS( pRect );
hr = S_FALSE;
}
}
}
