I have two JTree in two panels in a JFrame. I want to change the style(color and font) of nodes on drag and drop from one tree to the other.Please provide me a way to change the color of a JTree node permanently.
To start, you will need to have a data object that can handle style and color. You could subclass DefaultMutableTreeNode and add these data items with getts and setters
Then you’d need to create a custom TreeCellRenderer. I recommend extending DefaultTreeCellRenderer, and in the overridden handler, checking for your custom class, and modifying the JLabel output to use the Font and Color if these values are set
