      • registerDomHandler

        public <H extends com.google.gwt.event.shared.EventHandler> com.google.gwt.event.shared.HandlerRegistration registerDomHandler​(H handler,
                                                                                                                               com.google.gwt.event.dom.client.DomEvent.Type<H> type)
        Adds a new event handler to the widget.

        This method is used because we want the select box to register some event handlers on this widget, but we can't use Widget.addDomHandler(H, com.google.gwt.event.dom.client.DomEvent.Type<H>) directly, since it's both protected and final.

        Type Parameters:
        H - the event type
        Parameters:
        handler - the new event handler
        type - the event type object
        Returns:
        the HandlerRegistration for removing the event handler
