<hr><a name="_details"></a><h2>Detailed Description</h2>
A single node in a file tree table.
<p>
The node manages the details about one file, and if the file is a directory, populates a subtree with nodes for every directory item.<p>
The tree node reimplements <a class="elRef" doxygen="wt.tags:../../reference/html/" href="../../reference/html/classWt_1_1WTreeNode.html#9ab70c6020dbd9ea3204c625029a7a1b">Wt::WTreeTableNode::populate()</a> to populate a directory node only when the node is expanded. In this way, only directories that are actually browsed are loaded from disk.
