QT5.5 Demo - Simple Tree Modek Example

Qt's model/view architecture provides a standard way for views to manipulate information in a data source, using an abstract model of the data to simplify and standardize the way it is accessed. Simple models represent data as a table of items, and allow views to access this data via an index-based system. More generally, models can be used to represent data in the form of a tree structure by allowing each item to act as a parent to a table of child items.
