Detailed Description

The QLNode class is an internal class for the QList template collection.

QLNode is a doubly linked list node; it has three pointers:

1. Pointer to the previous node.
2. Pointer to the next node.
3. Pointer to the actual data.

Sometimes it might be practical to have direct access to the list nodes in a QList, but it is seldom required.

Warning

Be very careful if you want to access the list nodes. The heap can easily get corrupted if you make a mistake.
