JTree question
Hi All,
I would like some help with the following question.
I need to remove a node from my JTree that has children. Can you use the JTree like a linked list - that is add the new node, point the children to it ad then delete the old parent node?
When I delete a node that has children, the children get deleted also.
How do you usually deal with the problem? I don't really want to have to requery the database to build part of the tree.
Thanks,
Jackie.
There are methods on the Tree Nodes that allow you to traverse the list of children. You should be able to traverse that list, remove the children, and add them to the new node. Once that's done, then you would remove the parent node. The trick is, once this is done you need to notify the TreeModel that the tree structure has changed so that the TreeView can display all the changes to the user.
It's late and I don't know the calls off the top of my head, but what you are asking is possible.
