Hyperlinks in Dojo Tree
There is an example tree in the dojo campus with hyperlinks. They are not clickable. Does anyone have a dojo implementation with clickable links? Have you been able to determine which node/link was clicked? I am looking for sample code that does this.
Here is the sample code from dojo campus. How do I make these links clickable and how do I implement node selection from click of image?
Thanks.

You can do a connect to the onClick event on the Tree. When creating your Tree, add an extra onClick parameter to your constructor, pointing to a function with the following signature:
function myOnClickHandler(item, tree, evt){
//item is the node's DataStore item
//I forgot if tree is the whole tree or just the currtent node
//evt is the usual event object, with things like mouse position, etc...
console.log('clicked a tree');
}
var treeControl = new dijit.Tree({
model: treeModel,
showRoot: false,
_createTreeNode: function( /*Object*/ args) {
var tnode = new dijit._TreeNode(args);
tnode.labelNode.innerHTML = args.label;
return tnode;
},
onClick: myOnclickHandler // THIS LINE //
},
"treeOne");
