Java Forum / GUI / July 2005Need to change single node in JTree when JCheckbox selected
Hi, I need to change the icon of just a single, particular node in a JTree when a JCheckbox is selected. I understand I will need to extend DefaultTreeCellRenderer to just change the icon of a single node in the tree. I've also extended DefaultMutableTreeNode to give it more functionality. But, I'm not sure how to connect a checkbox to a particular tree node, and then have the Renderer update the tree, based on the change? Any help appreciated, Thanks, Gil I think I figured it out. I need to keep the Nodes in the JTree global so they can be accessed by ItemStateChanged or another listener attached to the checkbox. Then a field is changed in the node, which I have extended, and then JTree.updateUI() is called to update the renderer. This works okay so far. > I need to keep the Nodes in the JTree global so they can be accessed by > ItemStateChanged or another listener attached to the checkbox.
