This class serves as a base from which to implement individual display drivers. A GPEobject represents a single display device.

The following code example shows the methods that a GPE-based driver must implement.

// Configuration methods virtual SCODE
GetModeInfo( GPEMode *pMode, int modeNo )=0; virtual int
NumModes()=0; virtual SCODE SetMode( int modeId )=0; // Blit
methods virtual SCODE BltPrepare( GPEBltParms *pBltParms )=0;
virtual SCODE BltComplete( GPEBltParms *pBltParms )=0; // Line
method virtual SCODE Line( GPELineParms *pLineParms, EGPEPhase
phase = gpeSingle )=0; // Surface creation method virtual SCODE
AllocSurface( GPESurf **ppSurf, int width, int height, EGPEFormat
format, int surfaceFlags )=0; // Cursor methods virtual SCODE
SetPointerShape( GPESurf *pMask, GPESurf *pColorSurf, int xHot, int
yHot, int cx, int cy )=0; virtual SCODE MovePointer( int x, int y
)=0; // Palette methods virtual SCODE SetPalette( RGBQUAD *src,
unsigned short firstEntry, unsigned short numEntries )=0; virtual
SCODE SetPalette( PALETTEENTRY *src, unsigned short firstEntry,
unsigned short numEntries )=0; // Timing method virtual int
