Package org.eclipse.gef4.layout.listeners

This package contains interfaces for various listeners which can be registered on an ILayoutContext, as well as a support class which can handle the listener (un-)registration and firing of events.

See: Description

Interface Summary

Interface	Description
IContextListener	An IContextListener is notified about changes to context attributes such as the LayoutProperties.BOUNDS_PROPERTY which limits the area where nodes can be placed by layout algorithms, the LayoutProperties.PRUNING_ENABLED_PROPERTY which defines whether nodes can be pruned, and the LayoutProperties.DYNAMIC_LAYOUT_ENABLED_PROPERTY which defines whether layout algorithms are allowed to perform a layout pass in reaction to layout context events.
IGraphStructureListener	An IGraphStructureListener is notified about structural changes, i.e.
ILayoutListener
IPruningListener	An IPruningListener is notified about pruning changes, i.e. adding INodeLayouts to an ISubgraphLayout (pruning), or removing INodeLayouts from an ISubgraphLayout (unpruning).

Class Summary

Class	Description
IContextListener.Stub	A stub implementation of the IContextListener which contains empty implementations of the specified methods.
IGraphStructureListener.Stub	A stub implementation of the IGraphStructureListener which contains empty implementations of the specified methods.
LayoutListenerSupport	The LayoutListenerSupport can handle the (un-)registration of layout event listeners (IContextListener, IGraphStructureListener, ILayoutListener, and IPruningListener) and firing of events.
