event.id is the ID of the widget that sent the event, event.handler
is the widget to which the event handling function belongs. E.g.,
when you have a base widget with a lot of button widgets as childs,
you can associate an event function with the base widget only. When
a button is pressed, the base widget receives an event where event.ID
is the button that was pressed and event.handler is the ID of the base
widget. You'll need that in more complicated situations such as compound
widgets.
