In other words:
lightweight components are platform-dependently implemented to interact with
the local window manager.
heavyweight components use the lightweight components to implement
SWING. In fact SWING could have been written by you.
Note: it is dangerous to mix AWT (light) components with their SWING (heavy)
counterparts in ONE application: things might lock up.
