Thank you for your answer. Actually we would like to implement a selection behaviour for our SlideBar. We get rid of the scroll problem by using the child control mecanism you talk about. But now we are considering implementing the selection behaviour on our own on the SlideBar. That is to say having a "selectionChange" event triggered when one click on an item (a custom qooxdoo container) that returns the clicked item. So we checked in the List source code for directions but we found anything relevant (we go up the hierarchy to the qx.ui.core.selection.Abstract class, but we don't get when the link between events are made). Have you any idea of what we can do ?
