How to make addValueChangeHandler act just like addChangeHandler
- by Konoplianko
Hi. I have a problem.
I made a wrap widget that implements interface HasChangeHandlers
But i just can't fit events to each other.
public HandlerRegistration addChangeHandler( final ChangeHandler handler ) {
HandlerRegistration registration1 = dateFrom.addValueChangeHandler( handler );// Compile error
HandlerRegistration registration2 = dateTo.addValueChangeHandler( new ValueChangeHandler<Date>() {
@Override
public void onValueChange( ValueChangeEvent<Date> dateValueChangeEvent ) {
//have to fire handler ??
}
} );
return null; // what i should return here?
}
Thanks in advance !
