Updating a node that has a parent, even changing it from a TreeNode to
a BranchNode is trivial via det node.getParent().update() method. But
when a node is at the root of the hierarchy, I don't have a parent to
call update on. I guess I need to invoke some listener on the TreeView
itselv, but how? :)
I did get it working:
// Get index of current node
int idx = getTreeData().indexOf(node);
// Remove old node, add new node
getTreeData().remove(idx, 1);
getTreeData().insert(newNode, idx);
// Traverse all NodeListeners and tell them I updated index
pos at root (empty Path)
Sequence.Tree.Path path = new Sequence.Tree.Path();
for (TreeViewNodeListener l : getTreeViewNodeListeners())
l.nodeUpdated(this, path, idx);
.. but maybe there is a simpler/cleaner way? Maybe TreeView itself
should have a rootNodeUpdated method, in line with the functionality on
a TreeBranch? :)
