DisplayImpl.cpp@ 78784

Last change on this file since 78784 was 78784, checked in by vboxsync, 6 years ago
API: add getVideoModeHint. bugref:9472: API: let the GUI notice video mode hints from other sources. This Display object API method lets a caller retrieve information about the virtual monitor attached to a virtual display output, including the preferred mode (was: last mode hint). The name is legacy and will be changed to getMonitorInfo in 7.0.
