extend
public void extend(AbstractListing<T> grid)Description copied from class:
AbstractListing.AbstractListingExtensionAdds this extension to the given parent listing.
Overrides:
extendin classAbstractListing.AbstractListingExtension<T>Parameters:
grid- the parent component to add to
-
addComponentToGrid
protected void addComponentToGrid(Component c)Adds given component to the connector hierarchy of Grid.
Parameters:
c- the component to add
-
removeComponentFromGrid
protected void removeComponentFromGrid(Component c)Removes given component from the connector hierarchy of Grid.
Parameters:
c- the component to remove
-
getParent
public Grid<T> getParent()Description copied from interface:
ConnectorGets the parent connector of this connector, or
nullif the connector is not attached to any parent.Specified by:
getParentin interfaceClientConnectorSpecified by:
getParentin interfaceConnectorOverrides:
getParentin classAbstractListing.AbstractListingExtension<T>Returns:
the parent connector, or
nullif there is no parent.
-
getState
protected AbstractGridExtensionState getState()Description copied from class:
AbstractClientConnectorReturns the shared state for this connector. The shared state object is shared between the server connector and the client connector. Changes are only communicated from the server to the client and not in the other direction.
As a side effect, marks the connector dirty so any changes done to the state will be sent to the client. Use
getState(false)to avoid marking the connector as dirty.Overrides:
getStatein classAbstractListing.AbstractListingExtension<T>Returns:
The shared state for this connector. Never null.
-
getState
protected AbstractGridExtensionState getState(boolean markAsDirty)Description copied from class:
AbstractClientConnectorReturns the shared state for this connector.
Overrides:
getStatein classAbstractListing.AbstractListingExtension<T>Parameters:
markAsDirty- true if the connector should automatically be marked dirty, false otherwiseReturns:
The shared state for this connector. Never null.
