Re: Change style of TreeNode
Thanks a lot, Edvin.
I will try your answers to 2. and 3..
But I think, that overwriting the populateTreeItem method wouldn't help,
because i want to modify nodes of an existing tree, for example mark them
red if I click on them.
Any suggestions?

Change style of TreeNode
Hi everybody, I have some question regarding my existing wicket tree: 1. How can I change the style or css class of one or more TreeNodes? 2. How can I specify custom icons for some nodes? 3. How can i change the name, that will be shown in the tree, without changing the name of the userObject? Has somebody any ideas? Kai
Re: How to add nodes to a tree using Ajax
Hello,
2. Thanks, but your file contains only an empty class.
3. If the tree has ever 2000 nodes, it lasts maybe a little bit to long to
get all data at once from the database.

Re: How to add nodes to a tree using Ajax
HI everybody
I solved the first problem by my own by adding the following method to the
tree:
public DefaultMutableTreeNode getSelectedNode() {
Object selected = null;
try {
selected = this.getTreeState().getSelectedNodes().iterator().next();
} catch (NoSuchElementException nseEx) { }
return (selected instanceof DefaultMutableTreeNode)?
(DefaultMutableTreeNode)selected : null;
}
That worked for me without problems. Or is there an easier way?

Re: How to add nodes to a tree using Ajax
Hi,
thanks to both of you! Matejs code worked very fine, so i didn't tried gekes
version.
But now i have the next three problems/questions:
1. If i want to add a new node to the selected node, then i have to get the
selected node first. How can i do that?
2. Can i change the shown icons to custom ones?
3. Is it possible to load the root element only and reload the next level,
when you click the plus-image?

How to add nodes to a tree using Ajax
Hi,
how can I add nodes to a wicket tree using a AjaxLink?
I tried to add a node to the SimpleTree of this example:
http://www.wicket-library.com/wicket-examples/ajax/tree/simple.1
with this code:
add(new AjaxLink("addNode")
{
public void onClick(AjaxRequestTarget target)
{
List list = new ArrayList();
list.add("new node");
BaseTreePage.this.add(rootNode,list);
getTree().updateTree(target);
}
});
But the tree will not update itself.
Thanks in advance,
Kai
How to insert childs to a tree with Ajax
Hi,
I'm using an extendet wicket tree with an own tree model. I want to insert
child into the tree and want to update the tree with Ajax, but nothing
worked for me. I tried invalidateAll() and updateTree(). What can i do to
insert the childs with Ajax?
