Hi Derrell,

yes you are right. The list items are created by list item renderer. From 
there, i dont think you are able to walk up a line of layout parents.

What about listening to changeSelection event on list?

There you get the evt, and you are able to determine the target.
Just have a look on playground example.

You get the target by: 
evt.getTarget();

Betreff: [qooxdoo-devel] mobile: layout parent is null

I am trying to respond to touchstart and touchmove events on a container. When 
I receive a touchstart or touchmove event, I start with widget=e.getTarget() 
and walk up the the layout parent chain with widget=widget.getLayoutParent() 
until I find a container on which I which I can operate.

I'm finding, however, that if I add a qx.ui.mobile.list.List() to one of my 
containers, I get a parent of null during that walk, because e.getTarget() 
returns a qx.ui.mobile.container.Composite whose parent is a 
qx.ui.mobile.list.renderer.Default, which has a parent of null. This Default 
renderer is not properly in the layout chain!

If the touchstart begins on a list item, how can I figure out which container 
the list is in?

Thanks,

Derrell
