Hey,
you can either use closures [1] or function bind [2] to bring variables to
listeners. Other than that, you can also use the parent chain [3] of the
widgets to walk through the data. As I don't know the exact scope of your
request, I can't give you a better suggestion than these three.
Regards,
Martin

Hi,
I am using a tree widget and have multiple nested listeners so when a user
clicks on a folder it gets dynamically populated.
The problem I am having is a way of accessing variables outside of the
listeners scope. For example:
leaf.addListener("click",
function(e) {
alert(arguments[2]);
var label = new qx.ui.basic.Label(
WANT TO ACCESS VALUES OF ARTICLES[j]);
label.setRich(true);
container2.add(label);
WANT ACCESS TO THE CONTAINER HERE TOO
}, this, articles[j]);
I don't want to add everything to this.__ and make them global as I have a
lot of data and I have multiple variables so can't push them through
'this'.
Is there a cleaner way to do what I want ?
Thanks.
