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;

Field Description

memoryDevice

A memory device data structure.

hdc

A handle to a draw context.

typedef union TQAPlatformClip {
   HRGN                       clipRgn;
} TQAPlatformClip

Field Description
