Change History (most recent first):
|
|
|
|
<10> 11/5/93 IH Sync with Excelsior.
|
|
<SM9> 10/10/93 IH Sync with Excelsior.
|
|
<8> 8/26/93 IH #1108969 <KON>: Move Display Manager apple event constants to
|
|
this file.
|
|
<7> 8/16/93 IH #1099391 <KON>: Sync w/Reality. Get rid of a bunch of
|
|
preliminary data structures that are not used in DM 1.0.
|
|
<6> 8/4/93 IH #1101633,1098397,1101795,1101636,1102280 <KON>: Move Display
|
|
Manager gestalt definitions to gestalt headers. Changed
|
|
prototypes to use display state handles.
|
|
<5> 6/25/93 IH Clean up header and fix DMAddDisplay to include new parameters.
|
|
Added a couple new calls to handle smart monitor components.
|
|
<4> 6/1/93 IH
|
|
<3> 5/28/93 IH #1081805,1086363: Add activeOnly booleans for
|
|
DMGetFirstScreenDevice and DMGetNextScreenDevice. Synch
|
|
w/Reality. Change gestaltDisplayManagerAttr so that old versions
|
|
of bungee would ignore display manager w/different parameters.
|
|
Rearrange the selectors to make Finder calls private.
|
|
<2> 4/8/93 IH Add support for mode switching.
|
|
<1> 3/25/93 IH first checked in
|
|
<5> 3/24/93 IH Add DMSetMainDisplay trap call.
|
|
<4> 3/17/93 IH Move private calls to DisplaysPriv.h
|
|
<3> 3/5/93 IH Move more stuff to DisplaysPriv.h
|
|
<2> 2/25/93 IH Add new for desktop stuff and cleaned up header (removed unused
|
|
data structures). Made it work with ThinkC environment.
|
|
<1> 2/23/93 IH first checked in
