Detailed Description

template<typename T>
struct ui::util::TreeNodeModel< T >

auxiliary class to generate tree-like structures as a helper when creating QAbstractItemModel-like types

Usage:

• define struct with data memebers that will be hold on each node: struct MyData { int a, b, c; };
• and then use TreeNodeModel<MyData>::Node as base for your tree structure

Example of usage could be seen in: ui/network/bowman_model.h
