Adding drag and drop support to Jtree

Question

i want to add drag and drop support to my JTree application

i hav a created a custom DefaultMutableTreeNode subclass

hav a default TreeCellRenderer

what all things do i need to add and where?

Answer 1

The easiest way is to
1. Call tree.setDragEnabled(true)
2. set tree.transferHandler

There's a tutorial at: http://java.sun.com/docs/books/tutorial/uiswing/dnd/intro.html

You create a subclass of TransferHandler where you implement

canImport(JComponent comp, DataFlavor[] transferFlavors)

and

importData(JComponent comp, Transferable t)

Answer 2

Thanks

I tried making a custom TreeTransferHandler by extending TransferHandler

But couldn't make good in the direction I wanted

My objective is to be able to transfer TreePath.class instances within a JTree

a code snippet to show the working and application of the TransferHandler should help me

And again thanks for responding to my query
