How to set Icons in the JTree

[William Flores]

Hi guys!

I have a problem here. I'm implementing a JTree, but now I need set icons in each node.
I have searched about this, but I don't undestand very well how to do this.
Can someone help me? Please!

All you need is a TreeCellRender.

I have posted a very simple example for you here

There's no need to override DefaultTreeCellRenderer. It has its own methods to set the icons for opened nodes, closed nodes and leaf nodes. Just create an instance, set the right icons, and set that instance as the renderer.
