Comments

The LVectorBase::EnumVertices function calls your callback function as it gets the handle of each vector vertex.

To use this function, you must do the following:

  1. Derive a class from LVectorBase.

  2. Override the L_INT LVectorBase::EnumVerticesCallBack. Function in your class.

  3. Before calling LVectorBase::EnumVertices, you must call the member function LBase::EnableCallBack(TRUE).
