Description
This class is used for notification of selection set operations. Classes derived from this class can receive enhanced notification about ongoing selection set operations in AutoCAD and can modify the current selection set by adding entries to it and removing entries from it.
Modification of the current selection set is supported by the AcEdSelectionSetService class.
Creation or modification of the PICKFIRST set normally triggers an AcEdSSGetFilter::ssgetAddFilter() or AcEdSSGetFilter::ssgetRemoveFilter() notification.
It does not typically trigger an AcEdSSGetFilter::endSSGet()notification, except in the following circumstances: * If the user cancels the creation of a PICKFIRST set by pressing ESC, an AcEdSSGetFilter::endSSGet() notification is sent with a PromptStatus of eCancel.
* If an application calls the acedSSGet() or acedSSGetFirst() global function without starting a command or a LISP expression, an AcEdSSGetFilter::endSSGet() notification is sent with a PromptStatus of eNormal right before the AcEdSSGetFilter::ssgetAddFilter() notification is sent.
