Question

I have a JDialog with a JTree which includes a DefaultMutableTreeNode and its childs. I would like to have one of the nodes of tree focused when the JDialog is displayed. Just use the

tree.requestFocus();

doesn’t seem to work…any ideas?

Answer 1

1) If you know the row no. you can write tree.setSelectionRow(rownumber)
2) If you know the node, then tree.setSelectionPath( new TreePath(node.getPath()) );
