How do I assocaite a tree node object in java with an image?

Question

I have a Tree node. I want an image to be displayed beside the node name when the tree is viewed. How do I go about?

Answer 1

1. create an ImageIcon from your image

   ImageIcon icon = ....; (there are a number of ways to do this)

2. create an instance of DefaultTreeCellRenderer

   DefaultTreeCellRenderer renderer = new DefaultTreeCellRenderer();

3. set the leaf icon field of the renderer

   renderer.setLeafIcon(icon);

4. set the tree's renderer

   tree.setCellRenderer(renderer);
