source: vbox/trunk/src/VBox/Main/include/DisplayImpl.h@ 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.
