Is there a way to place custom icons in a JTree to replace the standard folders and pages?
Thanks,
Jeremy

I know how to change the Leaf Icon.
myDefaultTreeCellRenderer.setLeafIcon(new ImageIcon("somefile.gif"));
Probably similar for the nodes and root.

Happy Coding,

Ok, to set the Open Folder Icon you do the same except, setOpenIcon(new ImageIcon());
and the setClosedIcon(new ImageIcon()) sets the closed folder Icon.

I'm setting everything as a DefaultMutableTreeNode. I execute a SQL statement and step through the ResultSet to add each element as a node. Then I create a tree model passing that node to the constructor. Is there a way to change the icon of a node so that I don't have to recode the tree using leafs?

You can implement a TreeRenderer and use the getTreeCellRendererComponent to specify the icon of each node.
