I'll try to explain it better: By default, event listeners are attached
to the bubbling phase, where an event is dispatched on its target and
then propagates along the parent chain until it reaches the document's
root node. But the container intercepts the event and stops the event
propagation, so it will never reach the application root where the
listener is attached.
Instead, by adding the "true" option to addListener, we attach the
listener to the capturing phase, where the event travels down the DOM
tree starting from the root node, so it reaches the qooxdoo application
root node (and triggers the listener) before reaching the container.
Hope this clears things up.
Regards,
Daniel
