getChildComponents
public List<ComponentConnector> getChildComponents()Description copied from interface:
HasComponentsConnectorReturns the child components for this connector.
The children for this connector are defined as all
HasComponentss whose parent is thisHasComponentsConnector.Note that the method
ServerConnector.getChildren()can return a larger list of children including both the child components and any extensions registered for the connector.Specified by:
getChildComponentsin interfaceHasComponentsConnectorReturns:
A collection of child components for this connector. An empty collection if there are no children. Never returns null.
-
setChildComponents
public void setChildComponents(List<ComponentConnector> childComponents)Description copied from interface:
HasComponentsConnectorSets the children for this connector. This method should only be called by the framework to ensure that the connector hierarchy on the client side and the server side are in sync.
Note that calling this method does not call
ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler.onConnectorHierarchyChange(ConnectorHierarchyChangeEvent). The event method is called only when the hierarchy has been updated for all connectors.Note that this method is separate from
ServerConnector.setChildren(List)and contains only child components. Both methods are called separately by the framework if the connector implementsHasComponentsConnector.Specified by:
setChildComponentsin interfaceHasComponentsConnectorParameters:
childComponents- The new child connectors (components only)
-

public com.google.gwt.event.shared.HandlerRegistration addConnectorHierarchyChangeHandler(ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler handler)Description copied from interface:
