easy and fast JTree Cell Editor

Question

I have a JTree with a custom TreeModel and a custom TreeRenderer. The Tree Model contains a bunch of objects of different types. One of these types is displayed differently

Answer 1

A custom editor is required. MyTreeCellEditor, illustrated here, shows one approach. It updates an arbitrary attribute of a userObject, which is named Resource and held in a DefaultMutableTreeNode. As the attribute is text, it also uses the DefaultTreeCellRenderer. Your custom TreeModel probably manages a similar userObject that is the parent of your "objects of different types."
