The getFontMetrics call will only return a FontMetrics object once the
component has been "realized", i.e. has been made visible on the screen.

Your applet class really should not have a constructor. You should do
all your constructing in the init() method instead.

There are lots of examples of applets (with source) in the JDK release.
