Direct Known Subclasses:

Enclosing class:

TerraTreeViewSkin

protected static class TerraTreeViewSkin.NodeInfo
extends Object

An internal data structure that keeps track of skin-related metadata for a tree node. The justification for the existence of this class lies in the visibleNodes data structure, which is a flat list of nodes that are visible at any given time. In this context, visible means that their parent hierarchy is expanded, not that they are being painted. This list, combined with getNodeHeight(), enables us to quickly determine which nodes to paint given a graphics clip rect. It also enables us to quickly traverse the tree view when handling key events.

NOTE: some of this data is managed by TreeView and cached here to provide further optimizations during painting and user input.
