When you have a container with a number of child components, how can the container detect if the focus that was on one of the child components moved to a component outside the container. The container does not have to know which of the components inside the container lost the focus and which component outside the container got the focus, allthough it would be nice. The important thing is that the container knows about the focus shift from inside to outside. We would like to do this without every single component outside and inside the container sending messages to the container.
