Method Detail

addSelectionChangedHandler

com.google.gwt.event.shared.HandlerRegistration addSelectionChangedHandler(SelectionChangedHandler handler)

Called when (row-based) selection changes within this grid. Note this method fires for each record for which selection is modified - so when a user clicks inside a grid this method will typically fire twice (once for the old record being deselected, and once for the new record being selected).

NOTE: For updating other components based on selections or triggering selection-oriented events within an application, see the selectionUpdated() event which is likely more suitable. Calls to getSelection() from within this event may not return a valid set of selected records if the event has been triggered by a call to selectAllRecords() or deselectAllRecords() - in this case use the selectionUpdated() event instead.

Parameters:

handler - the selectionChanged handler

Returns:

HandlerRegistration used to remove this handler
