source: vbox/trunk/src/VBox/Frontends/VBoxSDL/Framebuffer.h@ 13305

Last change on this file since 13305 was 12449, checked in by vboxsync, 16 years ago

+changed IFramebuffer interface to report id of associated window if there's one
+changed sdl/qt3/qt4 frontends's interface implementations to report this id
+added VBoxSharedCrOpenGL hgcm service
(VBoxManage.exe setextradata lvm_winxp_sp2 VBoxInternal/Devices/VMMDev/0/LUN#0/Config/crOpenGLEnabled 1)
+changed crserver to be launched from vmmdev by guest request
+added hgcm call to supply desired window id to render spu
+changed guest icd driver to initialize hgcm and cause tcpip listener startup on host
+fixed spu finalization
+fixed q3 startup, again :)
