Its clear :-)
Using the List is perfect. This is how I would do it:
1. sub-class the List and define the event "delete" and "edit"
2. create the list item class with the buttons
3. add a 'parentList' property to the list item
4. add "execute" listeners to the buttons and dispatch "delete" and
"edit" events on the "parentList". Use a data event and pass the clicked
list item as argument:
delButton.addListener("execute, function(e) {
var parent = this.getParentList();
if (parent) {
parent.dispatchDataEvent("delete", this);
}
}, this);
5. override the list's "add" and "remove" methods. Set the "parentList"
property of the incoming list item:
add: function(item) {
this.base(arguments, item);
item.setParentList(this);
}
6. Now you can listen on the List's "delete" and "edit" events.
I hope this helps,
