I am looking on how I would go about extending TreeNode to include new config options. I currently have a TreePanel that uses a TreeLoader to generate TreeNodes. I am confused how I would accomplish this because TreeLoader calls TreeNode directly and I do not.
AbstractDocument.AbstractElement::
Adds a set of attributes to the element. abstract Enumeration < TreeNode. children Gets the attributes for the element. TreeNode. getChildAt (int childIndex)

This is currently how the TreeNode is generated...
TEXT
and I need to add extra attributes to the anchor that is created by TreeNode to make it look like so...
TEXT
I have looked at the Ext.etend tuts but I am still a little confused since I do not call TreeNode directly.
is there a way to add tootip options besides text for treenodes ::
[Archive] is there a way to add tootip options besides text for treenodes? working when not initialized using the qtip config attribute of the treenode.

Any help would be appreciated.
Thanks,

Ext.override(Ext.tree.TreeNodeUI, {
renderElements: function(n, a, targetNode, bulkRender){
//modified code
}
});
I was able to override the renderElements function instead as I was already passing the new attribute in the JSON array.
Thanks. This helped a lot. :D

Perfect! To override render was only my first thought... I'm glad it works.
You would probably had better to override method render of TreeNodeUI. The rough sequence would be:
Ext.override(Ext.tree.TreeNodeUI, {
render: function(bulkRender) {
// put original code of render here
}
});
Then you can add your functionality by altering and/or adding to the above render function.
On the road of development you may find that you need to override more methods. But the philosophy is same.
