IDirectDraw
Applications use the methods of the IDirectDraw interface to create DirectDraw objects and work with system-level variables. For a conceptual overview, see DirectDraw in the Graphics and Multimedia guide.
The methods of the IDirectDraw interface are organized into the following groups:
| PPC | SP | ||
|---|---|---|---|
| Cooperative levels | X | X | SetCooperativeLevel |
| X | X | TestCooperativeLevel | |
| Creating objects | X | X | CreateClipper |
| X | X | CreateSurface | |
| Device capabilities | X | X | GetCaps |
| X | X | GetDeviceIdentifier | |
| Display modes | X | X | EnumDisplayModes |
| X | X | GetDisplayMode | |
| X | X | GetMonitorFrequency | |
| X | X | RestoreDisplayMode | |
| X | X | SetDisplayMode | |
| X | X | WaitForVerticalBlank | |
| Display status | X | X | GetScanLine |
| X | X | GetVerticalBlankStatus | |
| Miscellaneous | X | X | GetAvailableVidMem |
| X | X | GetFourCCCodes | |
| Surface management | X | X | EnumSurfaces |
| X | X | FlipToGDISurface | |
| X | X | GetGDISurface | |
| X | X | GetSurfaceFromDC | |
| X | X | RestoreAllSurfaces |
The IDirectDraw interface, like all COM interfaces, inherits the IUnknown interface methods.
The IUnknown interface supports the following three methods:
| PPC | SP | ||
|---|---|---|---|
| IUnknown | X | X | AddRef |
| X | X | QueryInterface | |
| X | X | Release |
The IDirectDraw::Initialize method is not supported in Windows CE.
You can use the LPDIRECTDRAW to declare a variable that contains a pointer to an IDirectDraw interface. The Ddraw.h header file declares this data type with the following code.
typedef struct IDirectDraw *LPDIRECTDRAW;
Requirements
Pocket PC: Windows Mobile 5.0 and later
Smartphone: Windows Mobile 5.0 and later
OS Versions: Windows CE 5.01 and later
Header: Ddraw.h.
Library: Ddraw.lib.
