public class UndoablePropertySheetEntry extends PropertySheetEntry
UndoablePropertySheetEntry provides undo support for changes made to
IPropertySources by the PropertySheetViewer. Clients can construct a
PropertySheetPage
and use this class
as the root entry. All changes made to property sources displayed on that
page will be done using the provided IOperationHistory
.
NOTE: If you intend to use an IPropertySourceProvider for a PropertySheetPage whose root entry is an instance of of UndoablePropertySheetEntry, you should set the IPropertySourceProvider on that root entry, rather than the PropertySheetPage.
