A TreeList node's structure.
You can access nodes using the getRootNode() method and within some event handlers, for example, onNodesInitialized.
Contains all child nodes.
The node's data object.
Indicates whether the node has child nodes.
The node's key.
For plain data, the value of the key depends on the keyExpr option. For hierarchical data, the key can be generated automatically or set in the underlying Store of the data source.
The node's hierarchical level.
The level of the root node is -1. This node is not visualized and is used to access the full hierarchy of nodes. The root node's children have level 0, the children's children have level 1, and so forth.
The parent node.
Indicates whether the node is visualized as a row.
