node name not complete

In my JTree, sometime when I create the tree, some nodes name aren't complete. They are wrote with point at after the two first characters of the name (Ex. B1....). What can i do to be sure that the nodes name are completly writen?

Do you mean the text content ends with an ellipsis (three little dots)? If so, make theJTree a bit wider.

Yes, it's what I mean. The JTree is enough width because the previous node, which is longer, is correctly writen.Example :B1LONDON CorrectB2... Not correct (B2PARIS)

When you change the contents of the node, you'll want to call the appropriate method in your tree model to notify the JTree to redraw it. That's the nodeChanged() method if you are using a DefaultTreeModel.
