TextView Does Not Integrate Well
- My experience so far with TextView has shown that it does not
integrate well with the rest of YAHOO user interface library.
I've found three ways I could attach event handling to nodes in a
TreeView, and none of them work properly. All my current problems stem
from having to run the refresh() function as I add/remove nodes from
the dynamic tree.
1) addListener via the YAHOO.util.Event system does not work because
on refresh() of the tree, event handling added to the treeview nodes
are overwritten. This is made worse in that I want to attach a context
menu to each node, and these bindings appear to be lost after refresh.
2) The recommended method is to modify the href property of the node.
That way when refresh is called, your event handler is included. But,
to work with this system you have to write strings instead of simply
attaching first class function objects and so you lose the power of
Plus, I'm not sure how I would add my context menu listeners this way,
but I know that I shouldn't have to know either :)
3) Alternatively it's possible to hook in to the expanded and
collapsed events that are distributed by the TextView. But I need the
'click' event and these events are too high a higher level. For
example, I need to trigger the context menu which has nothing to do
with expansion/contraction of the treeview nodes.
