source: vbox/trunk/src/VBox/Main/src-client/GuestProcessImpl.cpp@ 77863

Last change on this file since 77863 was 77587, checked in by vboxsync, 6 years ago

Guest Control/Main: Implemented virtual guest object methods for session status changes to allow guest objects set their internal state accordingly. The guest session's object map now also keeps a (weak) pointer to the guest objects for handling the callbacks.
