According to the celua.txt file in the install directory

Treeview Class : (Inheritance: CustomControl->WinControl->Control->Component->Object)
createTreeView(owner)

properties
Items: TreeNodes - The Treenodes object of the treeview (ReadOnly)
Selected: TreeNode - The currently selected treenode


Treeview has a Selected property which tells you which node is currently selected.

TreeNodes have
TreeNode class : (Inheritance: TObject)
properties
Text: string - The text of the treenode
Parent: Treenode - The treenode this object is a child of. (can be nil) (ReadOnly)
Level: Integer - The level this node is at
HasChildren: boolean - Set to true if it has children, or you wish it to have an expand sign
...
Index: Integer - The index based on the parent
AbsoluteIndex: Integer - The index based on the TreeView's Treenodes object (Items)
Selected: Boolean - Set to true if currently selected
MultiSelected: Boolean - Set to true if selected as well, but not the main selected object

You can see the supported events in the form editor
