Method Detail

addDataArrivedHandler

com.google.gwt.event.shared.HandlerRegistration addDataArrivedHandler(DataArrivedHandler handler)

Notification method fired whenever this TreeGrid receives new data nodes from the dataSource. Only applies to databound TreeGrids where data is a ResultTree - either explicitly created and applied via setData() or automatically generated via a fetchData() call.

Note that dataArrived(), unlike TreeGrid.dataChanged(), only fires in limited circumstances - when data for a ResultTree arrives from the server due to a fetch or cache invalidation, or as a result of filtering. If you want to catch all data changes, you should instead react to TreeGrid.dataChanged().

Parameters:

handler - the dataArrived handler

Returns:

HandlerRegistration used to remove this handler
