Last change on this file since 4246 was 4131, checked in by vboxsync, 17 years ago

Main/Frontends: Added missing IConsoleCallback notifications (onDVDDriveChange, onFloppyDriveChange, onNetworkAdapterChange, onSerialPortChange, onParallelPortChange, onVRDPServerChange, onUSBControllerChange, onSharedFolderChange) to track third party configuration requests in frontends.
