How do I access a list item?

How do I access a list item in this event?

self.myList.addListener("changeSelection", function(e) {

var selection = e.getData();

console.log(self.myList.getSelection()[selection]);

}, this);

Re: How do I access a list item?

The variable "selection" in your example is an array with all selected list items, i.e. selection[0] gives you the first selected item.

Norbert

Re: How do I access a list item?

No, that doesn't seem to be the case. When I print the selection variable I get a single integer which corresponds to the iterator of the list.

When I try to run this code the function isn't defined:

self.myList.addListener("changeSelection", function(e) {

var selection = e.getData();

selection.addCssClass('item-selected'); // error

}, this);

Re: How do I access a list item?

Hi Tomas

e.getData() will return an instance of qx.data.Array, which is the selection; what you want to do is access selection.getItem(0) to get an instance of qx.ui.form.ListItem.

If you still have problems, please can you create an example in the playground? It’s much easier to help out if we can all share the same working example

Regards

John

Re: How do I access a list item?

Ah, you're on qx.mobile, I assumed qx.desktop (qx.ui.form.list). Can't help you there, I'm entirely immobile.

Re: How do I access a list item?

In reply to this post by Tomás Antunes

Aha, yes me too – I assumed you were on desktop too.

I’ve had a look at the code for mobile and AFAICT the item is not made available; the preferred method is to change the underlying model and ask the list to redraw itself. Here’s an example: http://tinyurl.com/hy2xzmh
