- Description

| Methods' Details |
treeNodesChanged
- Description
- Invoked after a node (or a set of siblings) has changed in some way.
The node(s) have not changed locations in the tree or altered their
children arrays, but other attributes have changed and may affect
presentation.
Example: the name of a file has changed, but it is in the same location in the file system.
To indicate the root has changed, TreeDataModelEvent::Nodes will contain
the root node and TreeDataModelEvent::ParentNode will be empty.

treeNodesRemoved
- Description
- Invoked after nodes have been removed from the tree.
Note that if a subtree is removed from the tree,
this method may only be invoked once for the root of the removed subtree,
not once for each individual set of siblings removed.
Use TreeDataModelEvent::ParentNode to get the former parent of the deleted node(s).
TreeDataModelEvent::Nodes contains the removed node(s).
