DXGetPartClass

Function

Returns by index only those parts belonging to the specified class.

Syntax

#include <dx/dx.h>

Object DXGetPartClass(Object o, int n, Class class)

Functional Details

Performs a depth-first traversal of the Object o and returns a reference to the nth (n>= 0) occurrence of a subObject with the requested class. The parts of a group may be enumerated by calling DXGetPartClass with successive values of n starting at 0 until NULL is returned.

For applying a function to every Field in a Group, DXProcessParts is a more efficient interface.

Return Value Returns the nth subObject of the requested class or returns NULL.
