C++
virtual ACDBCORE2D_PORT void modifyUndone( const AcDbObject* dbObj );
Description
This is one of the persistent reactor notification functions that can be overridden in a custom class derived from AcDbObject. The default implementation for this function is a return, so unless it is overridden it does nothing.
This particular function is called whenever the object sending notification is in the middle of an Undo operation which is undoing modifications made previously.
When this function is called, dbObj points to the object sending the notification. The sending object is open in a read-only state.
Parameters
| Parameters | Description |
|---|---|
| dbObj | Passed in pointer to object that has an Undo in progress |
