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?
If you override the populateTreeItem() method, you can add an
AbstractBehaviour to the item and override the onComponentTag method.
From there you can do tag.put("class", "yourValue").
2. How can I specify custom icons for some nodes?
Override the getNodeIcon() method of the tree.
3. How can i change the name, that will be shown in the tree, without
changing the name of the userObject?
I guess the simple solution would be to provide a toString() method on
your userObject that returns the desired value :)
Alternatively you could override the renderNode method of the Tree,
which by default does:
protected String renderNode(TreeNode node)
{
return node.toString();
}
Just get your userObject from the node and return the string you want
from there :)
