How to render a Tree with a preselected node?

["Emmanouil Batsis (Manos)" <ma...@abiss.gr>]

Looking around the APIs and all, but haven't figured out how to have a 
LabelTree rendered with the tree expanded properly to point to a 
preselected node.

To answer my own email, it's all about

// select the apropriate node, in my case a
// DefaultMutableTreeNode
tree.getTreeState().selectNode(selectedNode, true);

// call a recursive method to
// expand accordingly
expandToNode(selectedNode);

// the method can be something like
private void expandToNode(DefaultMutableTreeNode node) {
	tree.getTreeState().expandNode(node);
	if(!node.isRoot()){
		expandToNode((DefaultMutableTreeNode) node.getParent());
	}
}


I still need to figure out how to scroll into-view though, I've wrapped 
the trees into fixed-height divs.
