Windows Device and Clip Structures

QuickDraw 3D RAVE supports two types of devices and one type of clipping on Windows 32 systems. The available devices and clipping are defined by unions of type TQAPlatformDevice and TQAPlatformClip .

typedef union TQAPlatformDevice {
    TQADeviceMemory                     memoryDevice;
    HDC                                 hdc;
    struct {
        LPDIRECTDRAW                    lpDirectDraw;
        LPDIRECTDRAWSURFACE             lpDirectDrawSurface;
    };
} TQAPlatformDevice;


memoryDevice

A memory device data structure.

hdc

A handle to a draw context.

lpDirectDraw

 

lpDirectDrawSurface

 

typedef union TQAPlatformClip {
    HRGN                                clipRgn;
} TQAPlatformClip


clipRgn

A handle to a clipping region.
