GPE

This class serves as a base from which to implement individual display drivers. A GPE object 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    InVBlank()=0;
