File: DisplaysPriv.h
Contains: Private Headers for the Display Manager
Written by: Ian Hendry
Copyright: © 1993 by Apple Computer, Inc., all rights reserved.
Change History (most recent first):
<14> 11/5/93 IH Sync with Excelsior.
<SM13> 10/10/93 IH Sync with Excelsior for ROM build.
<12> 9/10/93 IH Fix cursor bug in horror ROMs and SuperMario.
<11> 8/26/93 IH #1108969 <KON>: Added some more debug defines. Added room for
res-independent QD info into state record.
<10> 8/16/93 IH #1099391 <KON>: Sync w/Reality. Fix apple event notification to
procs ptrs. Update DisplayMgr globals struct to match
DisplaysPriv.h
<SM9> 08-06-93 jmp Updated the timing constants used by the Display Manager for
non-intelligent displays.
<8> 8/4/93 IH #1101633,1098397,1101795,1101636,1102280 <KON>: Fix 1102280.
Propagate DisplayState handles through more calls. Add trap for
getting the decl rom info so it is easy to patch. Add Trap for
animation. Make GetROMMultiModeTable a trap so I can patch it.
<7> 6/25/93 IH Fix DM_AddDisplay to include new parameters. Changed macros to
use "_DisplayDispatch"
<6> 6/22/93 IH Fix multimode tables to have unsigned shorts.
<5> 6/1/93 IH Add private trap selector to get timing mode table.
<4> 5/28/93 IH #1081805,1086363: Reordered call selectors to make Finder calls
private.
<3> 4/8/93 IH Add support for mode switching. Added some prototypes for
DisplayMgrUtils.c
<2> 3/31/93 IH Clean up for SuperMario.
<1> 3/25/93 IH first checked in
<5> 3/24/93 IH Add Prototype for RecalcMenuBar. I may have added
DMSetMainDisplay here too. If so I will move it to Displays.h
next time I check these files in (are not modal checkin windows
great??).
<4> 3/17/93 IH Move private calls from Displays.h
<3> 3/5/93 IH Added more stuff.
<2> 2/25/93 IH Add new for desktop stuff
<1> 2/23/93 IH first checked in
