Q3Pick_GetType

You can use the Q3Pick_GetType function to get the type of a pick object.

TQ3ObjectType Q3Pick_GetType (TQ3PickObject pick);

pick

A pick object.

DESCRIPTION

The Q3Pick_GetType function returns, as its function result, the type of the pick object specified by the pick parameter. The types of pick objects currently supported by QuickDraw 3D are defined by these constants:

kQ3PickTypeWindowPoint
kQ3PickTypeWindowRect

If the specified pick object is invalid or is not one of these types, Q3Pick_GetType returns the value kQ3ObjectTypeInvalid.
