How to create a JTree from DefaultTableModel?
Dear friends:
I have a DefaultTableModel in following code, I can create a JTable from this DefaultTableModel , But I hope to create a JTree from this DefaultTableModel also, How can I do it?
I tried a lot of way to use
myTree= new JTree(model.addRow(rowData));
etc to create a JTree, but fails, what is wrong?
Any suggestion?
Thanks
sunny
