Attaching Custom Data

This group contains functions for associating arbitrary application data with graphical objects. More...

Detailed Description

This group contains functions for associating arbitrary application data with graphical objects.

This is different from Custom Data that can be attached to objects in the GLG Graphics Builder: Custom Data are stored only as GLG D, S or G data objects, while these functions may be used to attach data of an arbitrary type, such as a pointer to a structure.

The attached data are persistent only at run time and are not saved with the object when the drawing is saved.
