Hi,

How can I change the color of the node icons in a JTree?

I looked at DefaultTreeCellRenderer, but it only has methods for
changing the foreground and background colors of the text or outlining
the text. I couldn't find any methods that allow you to change the
color of the icons for the nodes. Is there such a thing? The only
other alternative I can think of is to actually change the icons.

Hi,

You may want to make your own sublass of Icon (this is nothing though)

Regards,

Arnaud

You cannot change color of icon, but you can change icon itself.

Easiest way to put replace icon:
UIManager.put("Tree.leafIcon", yourNewIcon);

"Tree.closeIcon"
"Tree.collapsedIcon"
"Tree.expendedIcon"
"Tree.openIcon"

SwingUtilities.updateComponentTreeUI(yourTree);
