Q3Shape_GetType

You can use the Q3Shape_GetType function to get the type of a shape.

TQ3ObjectType Q3Shape_GetType (TQ3ShapeObject shape);

shape

A shape object.

DESCRIPTION

The Q3Shape_GetType function returns, as its function result, the type of the shape specified by the shape parameter. The types of shapes currently supported by QuickDraw 3D are defined by these constants:

kQ3ShapeTypeCamera
kQ3ShapeTypeGeometry
kQ3ShapeTypeGroup
kQ3ShapeTypeLight
kQ3ShapeTypeShader
kQ3ShapeTypeStyle
kQ3ShapeTypeTransform
kQ3ShapeTypeUnknown

If the type of the shape cannot be determined or is invalid, Q3Shape_GetType returns the value kQ3ObjectTypeInvalid.
