ConsoleVRDPServer.cpp@ 79361

Last change on this file since 79361 was 78995, checked in by vboxsync, 5 years ago
PDM, Devices, FE, Main: allow size hints without notification for initial hints. bugref:9482: FE/Qt and Additions/WINNT: move away from -adjust size if...- This change allows size hints/monitor information to be set in a machine without generating an IRQ notification, for the purpose of setting the initial monitor information. It also uses the function for that purpose.
