Can you please add more Documentation to your API?
E.g. the class TreeExpansionBroadcaster is maybe usefull for me, as I am working on an own TreeTable.
Currently I try to understand the advantages/disadvantages of the AbstractTreeTableModel-classes vs TreeTableNode.
I want to write a treetable where the nodes are created on demand. For a custom file browser implementation.
So I don't want to load the complete filesystem into the treetable but only the part the user travers via the treetable.
For now I look for the best place to start the insertion mechanism when the user expand some node...
