|
|
*
|
|
* 18 8/25/98 6:27p Rvande
|
|
* Removed 4.2ism from MW build
|
|
*
|
|
* 17 8/25/98 11:50a Rvande
|
|
* removed redundant class scope in class definition
|
|
*
|
|
* 16 8/22/98 6:40p Pkeet
|
|
* Removed the 4.2 specific externs for 'pdd' and 'pdd4.' Added the 'ReleaseAll' member
|
|
* function to the 'CInitDD' object. Made a single global instance of the 'CInitDD' object.
|
|
*
|
|
* 15 7/24/98 11:45a Shernd
|
|
* Added IsCertified and Hardware checks for DirectDraw Init
|
|
*
|
|
* 14 7/20/98 10:32p Pkeet
|
|
* Upgraded to Direct3D 4's interface.
|
|
*
|
|
* 13 7/05/98 8:08p Pkeet
|
|
* Added a comment.
|
|
*
|
|
* 12 10/28/97 1:01p Shernd
|
|
* Changed the DirectDraw Video abstraction to load on an explicit location. This location is
|
|
* now in GUIApp.cpp. This change allows the ability to display error dialogs if DirectX
|
|
* cannot be initialized.
|
|
*
|
|
* 11 10/08/96 9:15p Agrant
|
|
* bool is now a typedef,
|
|
* pragma the bool warning off after DirectX turns it on.
|
|
*
|
|
* 10 96/08/09 10:58 Speter
|
|
* Changed for new CCom functionality.
|
|
*
|
|
* 9 96/08/05 12:14 Speter
|
|
* Now use new IDirectDraw2 pointer, has minor improvements over IDirectDraw.
|
|
*
|
|
* 8 96/06/12 20:38 Speter
|
|
* Code review changes:
|
|
* Now includes <DirectX/DDraw.h> in header file, with #undef bool for bug fix.
|
|
* Lists prefix for IDirectDraw.
|
|
* Changed struct CSize to class CDDSize.
|
|
*
|
|
* 7 96/06/07 18:32 Speter
|
|
* Made DirectDraw::CError::operator= call TerminalError.
|
|
* Moved error strings into resource file.
|
|
*
|
|
* 6 96/06/07 9:57 Speter
|
|
* Moved video mode stuff to new Video module.
|
|
*
|
|
* 5 96/05/29 17:10 Speter
|
|
* Changed init classes to have a per-file static instance rather than use inheritance to
|
|
* enforce order.
|
|
*
|
|
* 4 5/08/96 11:21a Pkeet
|
|
* Upped 'iMAX_MODES' to 32. Suddenly there are more modes... bitchin'.
|
|
*
|
|
* 3 96/05/01 17:54 Speter
|
|
* Changed CScreenMode to SScreenMode. Changed location of DDraw.h include
|
|
*
|
|
* 2 96/04/19 17:55 Speter
|
|
* Moved CSize<> template from .cpp to .hpp, because clients need it.
|
|
*
|
|
* 1 96/04/18 18:56 Speter
|
|
* First version
