"""
This example illustrates how to register to keyboard or mouse events.

There are two families of interfaces for this, called Listeners and Handlers.
In many cases the Handlers are easier to use and provide more flexibility. But
sometimes it's necessary to use the Listeners, as being shown below.

The Listeners usually need to be added exactly to the correct widget. So this
example adds them recursively them to all widgets below the given one.
