Shape Attributes

Each shape object has a set of attributes. Shape attributes are a group of flags that modify the behavior of the shape object. Constants for all shape attributes are defined in the gxShapeAttributes enumeration:

enum gxShapeAttributes { 
   gxNoAttributes,                     /* no attributes set */
   gxDirectShape           = 0x0001,   /* prefer GX heap */
   gxRemoteShape           = 0x0002,   /* prefer accel. memory */
   gxCachedShape           = 0x0004,   /* optimize drawing */
   gxLockedShape           = 0x0008,   /* lock shape geometry */
   gxGroupShape            = 0x0010,   /* treat as single shape */
   gxMapTransformShape     = 0x0020,   /* alter transform */
   gxUniqueItemsShape      = 0x0040,   /* copy picture items */
   gxIgnorePlatformShape   = 0x0080,   /* use glyph codes */
   gxNoMetricsGridShape    = 0x0100,   /* don't use hinting */
   gxDiskShape             = 0x0200,   /* unload this first */
   gxMemoryShape           = 0x0400    /* unload this last */
};

typedef long gxShapeAttribute;

The individual shape attributes are described further in Table 2-4 on page 2-16.
