RSE
Release 3.0

org.eclipse.rse.ui.filters
Class SystemChangeFilterPane

java.lang.Object
  extended by 

org.eclipse.rse.ui.SystemBaseForm
      extended by 
org.eclipse.rse.ui.filters.SystemChangeFilterPane
All Implemented Interfaces:
EventListener, IMenuListener, ISystemFilterStringEditPaneListener, ISystemConnectionWizardErrorUpdater, SelectionListener, org.eclipse.swt.internal.SWTEventListener, Listener

public class SystemChangeFilterPane
extends SystemBaseForm
implements SelectionListener, ISystemFilterStringEditPaneListener, IMenuListener

Since we have decided to allow the same editing in both the Change Filter dialog and the Properties page, we have to abstract the meat of the change filter dialog into a re-usable composite. That is what this is, and it is used by both the dialog and the property page.
