Interface GridEventManager

All Superinterfaces:

com.google.gwt.event.dom.client.BlurHandler, com.google.gwt.event.dom.client.ClickHandler, com.google.gwt.user.client.Event.NativePreviewHandler, com.google.gwt.event.shared.EventHandler, com.google.gwt.event.dom.client.FocusHandler

All Known Implementing Classes:

DefaultGridEventManager, HierarchicalGridEventManager

public interface GridEventManager
extends com.google.gwt.event.dom.client.FocusHandler, com.google.gwt.event.dom.client.BlurHandler, com.google.gwt.event.dom.client.ClickHandler, com.google.gwt.user.client.Event.NativePreviewHandler

This is an interface of grid event managers.

All classes which handle events produced by the grid must implement it.
Usually you won't have to implement this interface directly. Extend DefaultGridEventManager or HierarchicalGridEventManager instead.

Since:

1.3.0
