Class QueueTableModelInterceptor

java.lang.Object
  com.cosylab.gui.components.table.QueueTableModelInterceptor

All Implemented Interfaces:

java.lang.Runnable, java.util.EventListener, javax.swing.event.TableModelListener, javax.swing.table.TableModel

public class QueueTableModelInterceptor
extends java.lang.Object
implements javax.swing.table.TableModel, javax.swing.event.TableModelListener, java.lang.Runnable

QueueTableModelInterceptor wraps around TableModel and intercepts update events. All events are queued and dispatched in AWT thread. Similar events are integrated into one event. This makes updates from delegate GUI thread safe and prevents table to be updated unnecessary.

Tu use interceptor, create your model, create interceptor and pass your model as parameter, then add to the table interceptor as model. Listen to model events directly on your model and not on interceptor or on model, which is rerturned from the table (except if QueueTable becouse it completly hides the interceptor).
