Modification of a SWING tree node label

[MARTIN Herve \(EXT\)]

Hi,
I want to modify the label of a DefaultMutableTreeNode.
So I change the value returned by the method toString() of the node's user
object, and make the tree be repainted.

However if the label becomes longer that the original value,
the new label is displayed truncated, ended with '...'.

How can I get the complete label display?
Note: I don't want to create a new node with the new label, to replace the
existing node.

Hervé.

Hello Martin,

I went and looked at some code I did where I put long leafs of text on a
jtree. I didn't enoucnter the problem you speak of here, BUT, I DID put the
JTree on a ScrollPane. -Ike

I don't see this problem. One question though: are you just repainting,
or are you firing an appropriate TreeModelEvent. If the former, then
forget repainting and fire a TreeNodeEvent instead, dispatching it to
treeNodesChanged in the listeners. If you're using DefaultTreeModel,
then use the nodeChanged(TreeNode) method to do this.

ok, thanks Chris,
a call to nodeChanged() fixes my display problem

Hi,

Talking about long leaves of text, did you create leaves with a text on
several lines or just a very long one-line text?
