Netbeans JTree Linestyle

I'm having difficulty removing lineStyle strings in JTrees using Netbeans. In a standalone program, I can do this:

JTree myJTree = new JTree(); myJTree.putClientProperty("JTree.lineStyle", "None"); JScrollPanel myScrollPanel = new JScrollPanel(); myScrollPanel.setViewportView(myJTree);

But when I try to add this code to my created Netbeans GUI, I get what linuxyle seems to be by default Windows. Any ideas on what I'm doing wrong?

NetBeans installs its own system-wide interface.

You can fix this by overriding the setUI or updateUI methods on your JTree, where in addition to calling the super-execution method, you must configure your client.

Calling the following removes rows from JTrees worldwide in Swing

 UIManager.put("Tree.paintLines", Boolean.FALSE);

(Not sure how this interacts with NetBeans, though, sorry.)
