FileTreeModel Multiple Roots

Question

I use this code here to create a file tree model. I want it to browse files. How can I add multiple roots? E.g. list C:/, D:/, E:/.

Answer 1

A TreeModel can only have one root node, but you can use JTree.setRootVisible() to hide the root node when displaying the tree. Modify your model to have a virtual root node that contains each filesystem root (C:\, D:\, E:\, etc.), and call JTree.setRootVisible(false) on your JTree.
