# qlnode(3qt)

Internal class for the #include \<qglist.h\>

## NAME

QLNode - Internal class for the\

`#include <qglist.h>`

### Public Members

**QCollection::Item getData ()** \

## 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.

See also QList::currentNode(), QList::removeNode() and QList::takeNode().

## MEMBER FUNCTION DOCUMENTATION

## QCollection::Item QLNode::getData()

Returns a pointer (`void*)` to the actual data in the list node.
