- We can listen to lots of things besides a JButton. In
this example we listen to mouse movements (such as dragging). When
the mouse is dragged, a "Hello World" is dragged with with.
Unfortunately, it becomes smeared.
- Now the applet implements MouseMotionListener, we invoke
addMouseMotionListener(this) to init, and we
implement mouseDragged and mouseMoved as required by
MouseMotionListener. We do not use mouseMoved so it
has an empty body. But mouseDragged invokes paint
which draws the "Hello World" string to the screen at the mouse
coordinates. The font is set large.
