The 'QmitkDataStorageSimpleTreeModel' is a basic tree model, derived from the 'QmitkAbstractDataStorageModel'. It provides functions to accept a data storage and a node predicate in order to customize the model data nodes. Furthermore it overrides the functions of 'QAbstractItemModel' to create a simple qt list model.* This model can be used in conjunction with a 'QmitkDataStorageSelectionConnector'. This model is a "light" version of the classic QmitkDataStorgageTreeModel. The differences between both are the following: More...

Detailed Description

The 'QmitkDataStorageSimpleTreeModel' is a basic tree model, derived from the 'QmitkAbstractDataStorageModel'. It provides functions to accept a data storage and a node predicate in order to customize the model data nodes. Furthermore it overrides the functions of 'QAbstractItemModel' to create a simple qt list model.* This model can be used in conjunction with a 'QmitkDataStorageSelectionConnector'. This model is a "light" version of the classic QmitkDataStorgageTreeModel. The differences between both are the following:

This class currently does not support DragNDrop.
This class does not have the ability to change hirarchy or changes the layer property of nodes. This was skipped on purpose, because that is not the job of the storage model.
If a tree item A is removed this class does not attach children of A to the parent of A. Instead the complete tree representation is updated. This was changed on purpose because otherwise the internal representation of the model would not reflect the data storage graph anymore.
