entReferences(obj);

// Get the number of children:
int child_count = node->subjectCount();

// Get the references to all children:
QList<QObject*> children = node->subjectReferences();

\endcode

A limitation of this flexibility is that recursive tree structures are not allowed and this is automatically checked each time a new child is attached to a node. The Qtilities::CoreGui::TreeNode class provides many other useful functions to use. See the class documentation for more information.
