I use the class MyJTree with one MyDefaultMutableTreeNode (as a root) in its MyDefaultTreeModel.

MyJTree extends JTree
MyDefaultMutableTreeNode extends DefaultMutableTreeNode
MyDefaultTreeModel extends DefaultTreeModel

When I add a child node, it only seen if I double-click the root.
I want it to be seen automatically.
How do I do this easily?

Add a tree model listener to your model that expands a node when it is added to the tree.
