Detailed Description

A single node in a file tree table.

The node manages the details about one file, and if the file is a directory, populates a subtree with nodes for every directory item.

The tree node reimplements Wt::WTreeTableNode::populate() to populate a directory node only when the node is expanded. In this way, only directories that are actually browsed are loaded from disk.
