Last change on this file since 25881 was 25860, checked in by vboxsync, 15 years ago

Main: cleanup: get rid of VirtualBoxBaseProto, move AutoCaller*/*Span* classes out of VirtualBoxBaseProto class scope and into separate header; move CombinedProgress into separate header (it's only used by Console any more)
  • Property svn:eol-style set to native
