Re: How to lock a tree node so that it won't ever collapse

I have a DefaultMutableTreeNode that sometimes collapses on certain
hardware (like a trackball) when the mouse hovers over a child node
in
my JTree.
How can I lock this one single node from collapsing? It's a root
node
that's hidden so that all the second level child nodes appear,
making
them look like multiple root nodes.
You could attach a listener to your tree, and prevent any collapse
events for the root node.
The following link has a good example on how to use this feature.
